Disable manipulation of OLE Objects in Previewer

Hello to all,
I've developed several reports containing OLE objects stored in tables. These maybe Word Docs, Excel Sheets, images, etc. The OLE objects are displayed in the previewer / printout correctly. But when you doubleclick on an OLE object in the Previewer the OLE server app starts and you can manipulate these objects. When you return to the Previewer these changes can be printed but are not stored in the database (which is alright). Now here is my problem : as these printouts represent electronically signed documents, no change in its contents is allowed. How can i prevent the user form changing these objects ?
I hope I made my problem clear. Thanks to anyone who can help.
Regards,
Kai

Hi,
What is your Apex version?
Is your Apex instance runtime environment or can you login to INTERNAL workspace?
See this for Apex 4. Document do not say how disable demonstration app creation on runtime environment.

Print Preview of OLE object

My table has an OLE object.
In report it is arranged in tabular format (Arrage ->Table -> tabular)
so that if height of Other field(Let "Description") is grater than height of OLE object then height of that particular row will increased upto the height of Description.
In report view this works fine. But in print preview or in print size of OLE remains to original, it is not printing as it is appearing in Report view.
Please help me in this regard.

Memory problem if OLE-object references to WMF files

Hi there,
I have a report with an OLE object containing WMFs.
The graphic files are variable and their name is loaded from the database during runtime (path + filename).
Running the report leads to 185 pages, each one containing a different WMF.
If I preview the report in CR, everything looks fine.
If I print the report, the OLE object / graphic is left empty....
If I export the report to PDF (as an example) I get the error message 'memory full'. Reducing the data set to ~50, the PDF is created. But the pictures get resized (much bigger) and only parts are visible.
The machine I'm using doesn't have any memory problems.
The WM files are only 3 to 12 KB each.
If I convert the WMFs to JPG and use these within the report it works...
Problem with this: a loss of quality (it is necessary to stretch the pictures to certain size)
Thanks in advance for any ideas!

I'm using CR 2008 SP 3 on Windows 2003 Server

Format the pictures outside of CR for best results.

I would like to create a custom datagridview column containing text images and MS Word OLE objects

I am an old time LabView programmer going back to 2.0. But moved on with my career several years ago. But here I am back attempting a custom column in dataviewgrid control. .NET is hard. My goal is to read in an MS Word document and parse it out to a custom column. The column will contain regular old text, images and MS Word objects, sometimes called OLE objects.
There is scant information on creating .NET and labview when it comes to form manipulation. I have stuggled through the learning curve and now able to insert a text box column into a datagridview and add it to the form container and actually size it to the datagridview control. I've added a menu, but still figuring out the layout class. Did I say .NET is hard?
I know there must be a custom column created and even found a C# example, sorta. Trouble is the example uses easy stuff like override and private. It will take me another 3 weeks for that, darnit I'm getting lazy.
Does anybody out there have some example of a custom column in the datagridview?
If you ask to post code. I have nothing I would be proud to show.
The sorta go by: http://www.codeproject.com/Articles/31823/RichTextBox-Cell-in-a-DataGridView

This is what the progress looks like so far. I broke the tasks down in sub VIs. One to create a custom cell so I can add it to the column CellTemplate. The other to add the column to the control. My limited knowledge of .NET and the implementation in LV causes me to question the value of LV .NET.
The coding to create a TextBoxCell override with ImageCell CellTemplate. Honestly I'm guessing what to do, because the LV documentation on inheritance and overriding is poor at best.
The column coding to add the cell to the custom column.
Probe 19 always comes up with an error. The error is the standard 1172 with no clue what is causing it. The "index" will work on 0 or 1, I suspect bc the two cell types are 0 and 1 but nothing tells me that, just guessing.

OLE object error when using with Access 2003 and Adobe Reader X

I link to .pdf files in Access 2003 and since upgrading to Adobe Reader X yesterday, am unable to link to these files. I receive an error stating "A problem occurred while accessing the OLE object". It goes on to tell me to verify that the file is where I say it is and that it is accessible, which it is. I can go to that file in Adobe Reader and open it.

OLE object problem

I'm trying to make a report with OLE object in CR9 on XP Professional SP3. There is an image file "file_01.bmp". I place it in the report from "Insert"->"OLE Object" and chose "Create from file" with file path (not as icon, as image). But what I get in the report is black square with "file_01.bmp" caption below, and so in the report preview area. Double-clicking on it causes Object Packager warning.
What should I do to get an image (linked with a disk file) in report?
Thanks in advance.

I am having a simular issue as well. I finally got this to work on my laptop (where I have Crystal XI installed). I can also access the report from another computer with Crystal Runtime installed and it does update the graphic file as well, however, I cannot get this to work on my desktop computer. I have temporarily installed Crystal XI on the desktop to test this. Both Laptop and desktop have windows XP SP3 and most of the same applications installed. Here is what happens:
1) When I open the report, I get a message "Some Links could not be updated becasue thier sources are presently unavailable"
2) If I select the Links button I get a dialog that shows me the .bmp file.
3) I then select the Open Source button and I get a message "Failed to launch server application"
4) I open the report again and this time I select the Change Source and a dialog comes up asking me to select the source file.
5) I then select the source file and I get this message "Invalid Source:Do you want to correct it?"
6) I then select the Yes button, but nothing happens
The bmp file was created with Paint and Paint is registered for bmp files.
Any help on this would be appreciated.

Access 2003 Embedded OLE Object + Acrobat Reader 9.2 error on close?

This seems to be a known problem without a known solution.
We have a SQL database backend and an Access 2003 frontend. The Access client displays scanned PDF documents via an embedded OLE Object field.
Up until recently, we had been using Acrobat Reader 6.0 as the default viewer, but we switched up to 9.2 so that our staff could read external PDFs with security/encryption,etc. When an embedded PDF is viewed now through the Access client, an error is thrown when Acrobat Reader is closed, indicating that an OLE server was not registered, or needed to be re-installed. This did not happen with the Acrobat 6.0 client.
Is there any automatic behind-the-scenes file updates being performed when Acrobat Reader 9.2 shuts down? It seems like some information is trying to be written (maybe a timestamp?) and is kicking back an error when it can't update the target file.
Is there a workaround for this? I need the ability to read secured PDFs, but I also don't want my users having to needlessly deal with persistent error messages.

Programatically set ole object image path

Hi to all,
I'm using Visual Studio 2005, Asp.net 2.0-C# and CR 11 Sp2.
In my rpt file i added one ole object as bitmap i want to pass the data(image path) to this bitmap by programtically how to do this? Experts please help me

Hello, Winseelan;
If you are using Crystal Reports XI R2 (11.5) SP2 or later you can do this programatically using the 'Graphic Location' conditional formula.
To do this, perform the following steps:
1. Open the report in the Crystal Reports Designer.
2. Create a formula called "Location" that contains a temporary path string to an image file. For example, "C:\Images\Image1.jpg".
3. Right-click the image on the report and click 'Format Graphic'. The 'Format Editor' dialog box appears.
4. In the 'Picture' tab, click the 'Graphic Location' conditional formula button. The Format Formula Editor appears.
5. Call the "Location" formula from this conditional formula.
6. Save changes to the report.
7. In your application, you can now change the location of the image file at run time, by modifying the text in the "Location" formula programmatically using the following code:
myReport.DataDefinition.FormulaFields.Item("Location").Text = "C:\Images\Image2.jpg"
You can now view the image successfully when previewing your report in the application.

Report with OLE Object Problem (Crystal Report 11)

Post Author: ibertola
CA Forum: General
Hi all,I'm a new user, and I've got a problem with OLE object. I would like to have a report that show me ONLY one of many OLE (word document) in Crystal structure.I've created 3 section detail, and in each one I've insert OLE object (creating from a file, and LINK).So, if I change one document stored locally, and then refresh the report, the content doesn't change like the linked file! Actually I've got all locally Please help me.

Problem with ole objects

Hello to all,
I'm having a problem concerning the use of ole objects.
I'm using Oracle Forms 6.0.8.16.0 with Oracle Reports 6.0.8.1.7.1 on Windows 2000 with Oracle Database Server 9.2.0.4.0.
I have several forms with base tables including blob columns which are used to store ole objects. These could be MS-Word-documents or Bitmaps of signatures. When inserting these objects via "create new" and choose the object type, Word or Paintbrush opens and i can create my objects. After committing these changes to the database, these objects are printed in a report correctly. When inserting these objects via "create from file" or using a push button which is executing "initialize_container" with a file and committing to the database, i get an error while executing the report "REP-0082: Error executing SCA utility".
I want to use a push button to store my ole objects because the "create" dialogue is confusing our users because there is a huge list of all possible ole objects on the client.
Can anybody help with this ?
And to the Oracle Team, please don't suggest simply to upgrade to a higher patch level without looking at the problem. First, I tested all patch levels up to 16, with no change. Second, it's not easy to upgrade for an 24x7 application with hundreds of users in different countries with different ways of deployment.

Kai

Attention!!-don't use OLE object in Reports

If you are planning to use or is currently using OLE objects in Reports-please don't use it as the object maynot reload in future and your report may not even open in Report Builder.I got this message when opening the report containing OLE object:
REP-4004: Error occurred while restoring OLE object
and it refused to open up crashing my days of work.
The pity is I can't open my report even to remove the OLE object.

I know that is weird.I placed the object in the same directory-but in vain.Afterall, what's the logic of putting it in the same directory after embedding it?

The Picture of OLE object in the report can't be printed, and how to sovle dynamic OLE object based on path

Hi, everybody, I have a problem which the picture in the report can't be printed.I want to display some pictures in the reports and print them.So I insert the picture as OLE object, select the graph format and set graph location fomular with the path of the picture which is stored in the local machine. I run the system and generate the report, the picture is displayed correctly in the report, but when i print the report using ie's tool, the picture is gone and replaced with a little red mark. I want to use the new feature of dynamic graph location about the crystal report xi version, but I don't know where I should put the picture into on the web server and what the path is . Because my web server is installed in the another machine.I check the view source of html report and find that the system searches the picture under the crystalreportviewer11 folder on the web server.

Need to give the web server access to the folder
