Windows handle from C++ question

Hi,
I am showing a frame/panel/ (non canvas) Java component from a C++ application.
I have been looking for information about this but I found no information about obtaining the window handle and/or hdc of the opened window...
I need to embed this frame/panel in a "Windows window" :-)
Is it possible?
Thanks,
Katarn

Hi,
I need to do exactly the same as you mentioned and am not sure of how to go about it.Would it be possible to send me a small demo code of how to embed JavaWindows in Native(C++)windows.
It really would be a great help
Thanx in advance,
mickoo

How to Use AccessibleObjectFromWindow API in VBA to Get Excel Application Object from Excel Instance Window Handle

I need to get the Excel.application object from a window handle using AccessibleObjectFromWindow. I can't seem to make the code work. First, I successfully search for the XLMAIN windows. Then, when I get a handle, I execute the AccessibleObjectFromWindow
function. It seems to return a value of -2147467262 in all cases. Therefore, I believe that it is returning an error value. I can't figure out how to determine the meaning of this value.
If it is an error value, I believe that one or more arguments are in error. My best guess at present is that the GUID argument is incorrect. I have tried two GUID values: {00020400-0000-0000-C000-000000000046} and {90140000-0016-0409-0000-0000000FF1CE}.
I have seen both used in conjunction with OBJID_NATIVEOM. Neither one seems to work. I really would prefer not to use the second one as it has an Excel major and minor version number. I would hate to have to change this code, if a new minor version appeared.
The attached code has been commented to show which parts have been shown to work and which not. I'm at my wits end and really need help.
Thanks

I don't think you can return a reference to Excel's main window like that as you are attempting to do.
Ref:
http://msdn.microsoft.com/en-us/library/windows/desktop/dd317978(v=vs.85).aspx
It's relatively straightforward to return any workbook's window in any given instance, and in turn it's parent Excel app. Try the following and adapt as required (and include error handling) -

Note as written if an instance does not have any loaded workbooks a reference will not be returned (though a workbook can be added using DDE, but convoluted!)
FWIW there are two other very different approaches to grab all running Excel instances though something along the lines of the above is simplest.

Why i'm getting exception InvalidOperationException: Invoke or BeginInvoke cannot be called on a control until the window handle has been created ?

I have a backgroundworker1 dowork event and inside:
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
BackgroundWorker bgw = (BackgroundWorker)sender;
if (bgw.CancellationPending == true)
return;
else
this.BeginInvoke(new MethodInvoker(delegate
timer1.Stop();
Button1Code();
timer1.Start();
trackBar2.Enabled = false;
trackBar1.Enabled = false;
while (true)
bitmaps = ImagesComparison.get_images_with_clouds(b1);
for (int i = 0; i < bitmaps.Length; i++)
ConvertTo1or8Bit.BitmapToGIF(bitmaps[i], @"c:\convertedgifs\" + i.ToString("D6") + ".gif");
break;
The exception is on the BeginInvoke part.
In the last few days i was running the program many times and i didn't have this exception even once.
And now every times i'm running it i'm getting the exception.
System.InvalidOperationException was unhandled by user code

Window inheritance problem, implementation question

Hi!
I have a window inheritance and implementation question. I'm using
Forte 3.0.J.1.
I have a super (base) window with a PushButton on it. I want to
handle the Click event of the button in this super window therefore
I create an event handler.
<MyBtn> : PushButton
I create a sub window inheriting from the previous super window.
I put some data widgets on it and group all of them (the inherited
button as well) into a GridField. When I set the mapped type of the grid
the name of the inherited PushButton widget changes:
<MainGrid.MyBtn> : PushButton
When I run the application I get a SystemException with the
message:
Attempt to register an event on a NIL object (qqds_C_FieldWidget, 10).
Traceback:
SuperWindow.EH at line 0
SubWindow.Display at line 5
C++ Method(s)
UserApp.Run at offset 105
It is quite understandable that in runtime there is no widget called
<MyBtn>
and the event handler of the super class fails.
But what I don't know : after specifing a mapped type of a GridField why
changes
the name of those widgets that haven't got mapped type e.g.: PushButton,
PictureButton etc.
How to solve this situation?
I made a sall example which i send in attachment.
Thanks for any help and advice in advance...

Management of window handles across sessions

Hi All,
I have a single menu navigation html(image icon per module) for my application modules. Can this navigation menu be used across the new browser sessions created. i.e, the menu need to be having the window handles of all the sessions created on a client m/c.
Can I acess the window handle in javascript of one session from another session?
Its ok even if it is IE specific.
Thanks
Venu.

I think the question from me is not clear. For an Application instance, I have the window handles available in the application. What if I open 2 application instances and I need to communicate one window handle of one application instance to another window handle of another application instance...This clearly communicates that these 2 applications are 2 separate session instances. Is it knowing the window names on the client m/c helps...can I get window handle in this case?
Thanks

Is there a way to reinstall windows 7 from an erased disk? HP support states there is

Hello,
I completley erased the hardrive on a Compaq Presario CQ57 that I plan to sell. I don't have the recovery discs to reinstall Windows 7 Professional 32 bit.
I phoned HP and they they told me that although the hard drive is wiped clean, there is a partition that still houses the operating system and does not require disks. However, they stated they would have to charge an out-of-warranty fee of $59.99 for the information on how to do this. Declining such, they stated someone on the forum should be able to help.
I have searched the forum but have not found a way to restore Windows 7 on the notebook without recovery disks so far. Was HP support mistaken about bein able to restore Windows without disks?
Thank you.

When requesting assistance, please provide the complete model name and/or product number of the HP computer in question. HP/Compaq makes thousands of models of computers. Without this information it may be difficult or impossible to assist you in resolving your issue.
The above requested information can be found on the bottom of your computer or inside the battery compartment. Please do not include your serial number. Please enter the model/product information into HP's Online Consumer Support page and/or post it here for our review.
If you only erased the Windows partiton and left the factory recovery partition intact, then yes you can possible recovery the computer with out the discs. If you ereased the entire disc, there is no way to recover the computer to a factory like state without the HP Recovery Disc set.
Please enter you computer information HERE and select "Drivers", then the original OS to see if an HP Recovery Disc set is available from HP. You can also see if third party vendor www.computersurgeons.com has an HP Recovery Disc set available for your computer.
Alternatively, if you can still can still read the 25-digit product key on the Microsoft COA affixed to your computer, please see "How to Install Windows 7 Without the Disc" to download Windows 7, create the Windows installation media, and install Windows. If you prefer to install Windows 7 from a USB Flash Drive, please download the Windows 7 USB/DVD download tool to create a Windows 7 SP1 USB Flash Drive. Please note that you will have to source the needed drivers from HP or directly from the chipset manufacturer's websites. This method will result in a plain Windows installation with no HP customization.
If you have any further questions, please don't hesitate to ask.

Can't remove Contains() handler from SqlFunctionCallHandler - why?

I'm trying to amend some Entity Framework functionality at runtime by using reflection.
The following code snippets I've been using to get some feeling for the Entity Framework's internal functionality. Please don't ask what I'm using this for - at this stage it's just a test anyway.
My code is supposed to remove the Contains() handler from Entity Framework, so a query like this shall fail:
foreach (T1 a in (from x in ctx.t1
where x.Name.Contains("Man")
select x).DefaultIfEmpty()) if (a != null) Console.WriteLine(a.Name);
However, I don't seem to be able to remove the Contains handler at run-time.
Can someone please enlighten me on why this doesn't work?
Here's the code I've been using (I've omitted as much as I could to make the code snippet small):
using System;
using System.Data.Entity;
using System.Data.Entity.SqlServer;
using System.Diagnostics;
using System.Linq;
using System.Reflection;
using System.Reflection.Emit;
namespace EF_Contains_Override
internal class Program
static private void removeContains()
Type type = Assembly.GetAssembly(typeof(SqlFunctions)).GetType("System.Data.Entity.SqlServer.SqlGen.SqlFunctionCallHandler");
FieldInfo fi = type.GetField("_canonicalFunctionHandlers", BindingFlags.Static | BindingFlags.NonPublic);
object functionHandlerList = fi.GetValue(null);
MethodInfo method = functionHandlerList.GetType().GetMethod("get_Item", new Type[] { typeof(string) });
object origContains = method.Invoke(functionHandlerList, new object[] { "Contains" });
method = functionHandlerList.GetType().GetMethod("Remove", new Type[] { typeof(string) });
Debug.Assert((bool)method.Invoke(functionHandlerList, new object[] { "Contains" }));
static private void Main(string[] args)
Database.SetInitializer<EFContains>(new MyInitializer());
removeContains();
using (EFContains ctx = new EFContains())
foreach (T1 a in (from x in ctx.t1
where x.Name.Contains("Man")
select x).DefaultIfEmpty()) if (a != null) Console.WriteLine(a.Name);
Console.WriteLine("Press any key to continue ...");
Console.ReadKey();
Given the following seed, the above select should throw an exception because a Contains() handler no longer exists:
using System.Data.Entity;
namespace EF_Contains_Override
public class MyInitializer : DropCreateDatabaseAlways<EFContains>
protected override void Seed(EFContains context)
context.t1.AddRange(new[] { new T1("Hey Man"), new T1("No, woman, no cry") });
context.SaveChanges();
Still people out there alive using the keyboard?
Working with SQL Server/Visual Studio/Office/Windows and their poor keyboard support they seem extinct...

Hello BetterToday,
With your provided code and the resource code of Entity Framework downloaded from
here, I created a similar query with yours:
using (DFDBEntities db = new DFDBEntities())
var result = (from o in db.TestTables
where o.TestName.Contains("1")
select o).ToList();
With the resource, the all method are called to help generate the T-SQL are:
SqlGenerator.GenerateSql, SqlGenerator. VisitExpressionEnsureSqlStatement, SqlGenerator. VisitFilterExpression,
and in the SqlGenerator.Visit, we see that it converts the Contains to the Like filer and then it called method is WriteSql, we can see that the static class System.Data.Entity.SqlServer.SqlGen.SqlFunctionCallHandler is not called, so it
would does not affect query even after removing the contains method.
After searching more, my consult is that for methods as Contains/StartWith/EndWith and some other methods could be translated to TSQL directly, this behavior are by designed.
You could try with other method as the 'TOLOWER' as:
static void Main(string[] args)
try
#region https://social.msdn.microsoft.com/Forums/en-US/82aaca54-f1cd-47d3-b97c-254ec7b3e8bf/cant-remove-contains-handler-from-sqlfunctioncallhandler-why?forum
removeContains();
using (DFDBEntities db = new DFDBEntities())
var result = (from o in db.TestTables
where o.TestName.ToLower() == "1"
select o).ToList();
#endregion
catch (Exception)
static private void removeContains()
Type type = Assembly.GetAssembly(typeof(SqlFunctions)).GetType("System.Data.Entity.SqlServer.SqlGen.SqlFunctionCallHandler");
FieldInfo fi = type.GetField("_canonicalFunctionHandlers", BindingFlags.Static | BindingFlags.NonPublic);
object functionHandlerList = fi.GetValue(null);
MethodInfo method = functionHandlerList.GetType().GetMethod("get_Item", new Type[] { typeof(string) });
object origContains = method.Invoke(functionHandlerList, new object[] { "ToLower" });
method = functionHandlerList.GetType().GetMethod("Remove", new Type[] { typeof(string) });
Debug.Assert((bool)method.Invoke(functionHandlerList, new object[] { "ToLower" }));
It would throw an which says “{"'TOLOWER' is not a recognized built-in function name."}” I think it is you except.

Use a window handler in a webutil_c_api.invoke

Hi
I need to get the window handler of the forms, but I always get 0 from get_window_property( 'my_win',WINDOW_HANDLE )
and wen I ran the function:
webutil_c_api.invoke(ps_dll,'TWAIN_AcquireToFilename',func_param_acq);
the function send me a messagebox of "invalid window handler", then the twain execute well the function and when it finish, the web browser window is closed.
Can somebody tell me what is wrong ?
Is not possible to use a C function in a dll with webutil_c_api, that needs a window handler as a parameter
Thanx in advance

Removing Windows 8 from my MacBook Pro?

Hello,
I currently have windows eight installed on my partition. I want to uninstall it so I will be able to run it with parallel desktop. Parallel currently does not support Windows 8 from Bootcamp.
My question is in order to erase windows 8 what format should I click on? As shown in the screenshot. It was originally highlighted on the last selection ( windows) however, it will not give me the option to erase.
Thanks,
Jonathan

Use Boot Camp Assistant to remove the partition, your disc will be returned to as it was before the partition was made, do not use Disk Utility.

Windows handle of the Main Window of the SAPGUI

Hi experts,
i need to have the window handle value of the window of the Main MDI window of the SAP GUI from ABAP, does anyone know a FunctionModule or something like this to retrieve this information?
I need to retrieve information about the geometry of the window (Like the coordinates of the window,..).
(For 46C)
Can anyone help me?
Many thanks and regards,
Gianpietro Dal Zio

If this is not something you hope to do programatically .. MS's SPY++ utility will be of assist. If you wish to do it programmically .. I'm a newbie and am unaware of an FM to do it, though if it is possible to call a WIN API Function from ABAP, that may be a course you could persue

Windows 8 from TechNet/MSDN to Windows 8.1 via Windows Store, Possible ?

Windows 8 from TechNet/MSDN can not be updated to Windows 8.1 via Windows Store.
It says this edition dose not support update via Store.
Considering that Win8.1 is free for Win8 users, is there a way to bypass this ?
Can MSDN Windows 8 be converted to Proper Retail Win8 ?

Windows 8.1 available from MSDN Subscriber Downloads as well Vladimir, so you can get it from there if your subscription is still active.
More information about updating to 8.1 on the Windows Store available here: http://windows.microsoft.com/en-us/windows-8/why-can-t-find-update-store.
This is more of a Windows 8 question because the windows team controls how updates work for their product. I'd post this question over in http://answers.microsoft.com in the Windows section.
Thanks,
Mike

Windows Media Player keeping Automatic Maintenance window/Windows Updates from doing auto-restart

I have a system that is connected to a domain, and it runs a video playlist in Windows Media Player for digital signage upon bootup (and auto-login). WMP is set to loop the videos over and over again, but it also is preventing automatic updates from
installing and/or auto-restarting at 3:00AM in the morning (and yes, the system power management is set to keep the computer on all the time).
How can I fix this?
I have a GPO set up to install updates and restart automatically (option 4). I tried the GPO option to use the Windows 8 maintenance window to install updates, and also tried turning that option off and just using a 3:00AM restart period. Neither
option seems to work, so it looks like Windows Media Player is preventing an auto-restart to finish the update installation. Is there any way around this, so that Windows Media Player doesn't stop Windows Updates from doing its job? I don't care
if that means the video stops playing because it just starts up again on the next bootup.
I looked at the WMP GPO's and the only option that sounds like it's related is the option to turn on or off the auto-updating of media info for WMP, but it has nothing to do with what I'm trying to accomplish. If I missed something, let me know.
If there is some other way to accomplish this, such as associating and launching the playlist file with the Xbox Videos app, I would be fine with that, but I need it to loop the playlist continually (I also use the Shuffle option
in WMP - ***see note below for another question). I still want the system to automatically install updates and reboot on a regular schedule despite the video playing in the foreground.
***Side question: is there any way to turn Repeat and Shuffle options on in WMP without having to load the GUI (for scripting a playlist)?
Just FYI: this system is actually using Windows Embedded 8.1 Industry Enterprise (from a MAPS account), but it isn't customized aside from not having the standard WinRT apps from a stock Win 8.1 install loaded - it is a stock install from the ISO.
From what I understand, it is the same as Windows 8.1 Enterprise, except that it is only licensed to be used as an "appliance" machine for a single role - which it is. So I'm assuming that there are no actual differences from a "regular"
Windows 8.1 SKU that would cause this issue. If I am completely mistaken about this, please notify me on it. The reason I'm making this statement is in case there are any differences in Embedded 8.1 Industry Enterprise that I am not aware of.
Otherwise, I welcome any assistance that would target a "regular" version of 8.1 Enterprise. NOTE: Someone said to post this into the Windows Embedded forum, but the only one that exists is the one for POSready - and this is HARDLY the
POSready version of Windows Embedded that I'm using.

Hi,
Did you use the policy Local Computer Policy\Administrative Templates\Windows Components\Windows Update\Always automatically restart at the scheduled time?
I noticed an description "restart with logged on users for scheduled automatic updates installations" policy is enabled, then this policy has no effect." it means if system installed some updates which unneeds restart computer, this policy would has no effect.
In my opinion, your problem should not caused by WMP setting. please check your installed updates whether they need restart computer.
In addition, Power Managment in Control Panel also can prevent the schedule task running.
Control Panel\System and Security\Power Options\Edit Plan Settings\Change advanced power settings\Sleep\Allow wake timers
Please make sure this option is enable.
