How to Read the one Source Column data and Display the Results

Hi All,
I have one PR_ProjectType Column in my Mastertable,Based on that Column we need to reed the column data and Display the Results
Ex:
Pr_ProjectType
AD,AM
AD
AM
AD,AM,TS,CS.OT,TS
AD,AM
like that data will come now we need 1. Ad,AM then same we need 2. AD also same we need 3. AM also we need
4.AD,AM,TS,CS.OT,TS in this string we need AD,AM only.
this logic we need we have thousand of data in the table.Please help this is urgent issue
vasu

Hi Vasu,
Based on your description, you want to eliminate the substrings (eliminated by comma) that are not AD or AM in each value of the column. Personally, I don’t think this can be done by just using an expression in the Derived Column. To achieve your goal, here
are two approaches for your reference:
Method 1: On the query level. Replace the target substrings with different integer characters, and create a function to eliminate non-numeric characters, then replace the integer characters with the corresponding substrings. The statements
for the custom function is as follows:
CREATE FUNCTION dbo.udf_GetNumeric
(@strAlphaNumeric VARCHAR(256))
RETURNS VARCHAR(256)
AS
BEGIN
DECLARE @intAlpha INT
SET @intAlpha = PATINDEX('%[^0-9]%', @strAlphaNumeric)
BEGIN
WHILE @intAlpha > 0
BEGIN
SET @strAlphaNumeric = STUFF(@strAlphaNumeric, @intAlpha, 1, '' )
SET @intAlpha = PATINDEX('%[^0-9]%', @strAlphaNumeric )
END
END
RETURN ISNULL(@strAlphaNumeric,0)
END
GO
The SQL commands used in the OLE DB Source is like:
SELECT
ID, REPLACE(REPLACE(REPLACE(REPLACE(dbo.udf_GetNumeric(REPLACE(REPLACE(REPLACE(REPLACE([ProjectType],'AD,',1),'AM,',2),'AD',3),'AM',4)),4,'AM'),3,'AD'),2,'AM,'),1,'AD,')
FROM MyTable
Method 2: Using a Script Component. Add a Derived Column Transform to replace the target substrings as method 1, use Regex in script to remove all non-numeric characters from the string, add another Derived Column to replace the integer
characters to the corresponding substring. The script is as follows:
using System.Text.RegularExpressions;
Row.OutProjectType= Regex.Replace(Row.ProjectType, "[^.0-9]", "");

Hi Prashant,
Native SQL commands in ABAP are placed between EXEC SQL and ENDEXEC. You can place all your statements in between these EXEC SQL and ENDEXEC in a report.
EXEC SQL [PERFORMING <form>].
<Native SQL statement>
ENDEXEC.

How to execute a string formula and assign the result to a number field

How to execute a string formula and assign the result to a number field
Hi,
we have a function that returns a string like this:

After we should calculate this string and assign the value to a numeric block field
Example:
k number(16,3);
k:=fun1('(45+22)*78/23'); where fun1 execute and translate to number the string.
Does exist a function like fun1 ??
How can we do ?

Hello,
this is the code that does the job:

Remote Call to Blazeds and displaying the result set in grid

Hi,
I want to call a remote method using Flex application from Blazeds and display the values in DataGrid. Can anyone help in this ?

    </mx:Panel>
</mx:Application>

There may be other ways to do this but here's what I would do:
1) add a results method to the remote object:
src.result="onResult(event.result)";
2) add the callback method: private function onResult(event : * = null)
:void{
                                                     if(event is
ArrayCollection)
                                                            myData =
ArrayCollection(event);
3) add the variable: private var myData:ArrayCollection;
4) make the dataProvider for the grid use the my data :
dataProvider=""
You can probably avoid all this by adjusting your dataProvider. I am just
not sure what it would be without experimenting. But definitely not what
you have. Maybe just {svc.result}.

How to join two lists and display the results in datasheet view.?

hello,
i have two lists that i would like to join, i know a method that has been described in the link below
http://www.codeproject.com/Articles/194252/How-to-Link-Two-Lists-and-Create-a-Combined-Ciew-i
however, here the data view is only limited to 30 rows and my resultant list is huge. I would like to know if there is a possibility to view the resultant list in a data sheet view ?

I don't believe you can use the OOTB Datasheet view when joining lists. However, you should be able to increase your limit from 30 items to as many as you need (that doesn't trip the threshold set in Central Admin).

How to search XML data from a HTTPMultiService and display the result on the Spark List

Hello all,
I am totally new to Flash Builder and Actionscript and hope someone might be able to help me out. I basically create a mobile app with a single view. The view has a TextInput as a search box and a search button. I conntected a Data/Service using a local XML file and bind the Data to a Spark List. Innitally the List will show nothing until the user enter the search term and hit the button. The List suppose to show the XML data that match the search term.
Now is my problem. I cannot make the List to show the data that match the search text. The List just shows ALL the data.
Here are my MXML code:

Call a JSP from applet and display the results in the browser

Hello All,
I have written an applet which performs some functionality at the clinets browser. When the applets method finishes exectution, I would like to call
a jsp. The results of the JSP should be displayed like a normal page in the browser.
I tried creating a HttpURLConnection and calling the jsp but two things happened
1. The jsp call failed because the applet doesn't have a valid session id.
2. even if I disable the valid user check at the jsp, the results of the jsp are returned as a set of bytes to the applet. They are not displayed in the browser window.
Then I tried applet.getAppletContext().showDocument()... However with this api I cannot do a POST operation on the JSP with some input data because this takes only a URL as an input parameter.
Please help me in this problem and I will be very gratefull to you.
1. applet uses the same session id as the browser so that when applet makes a request to the jsp it does not get user invalid exception.
2. the results of the jsp are displayed on the browser and not given to the applet.
Thank you so much for your help.
regards,
Abhishek.

I hope this can help you

Is it possible to read and write to a file at the same time and display the results in a RichTextBox?

Hi All,
I have a purpose in winforms to have a "notepad like" editor that saves what ever i type to a file on the hard drive and reads from based.
So what i have is a tab with a richtextbox docked to fill. I would like to have that richtextbox read from a file on the hard drive, then save the changes i type when i either click off the tab or live if possible.
I wills state that i am fairly new to the c# game and if this is possible and someone could post an example that would be awesome and totally appreciated.
Thanks,
jAC

For those that are looking for the solution I went with here are the details
Reading the file:
// Wish List Section
wishListRichTextBox.ResetText();
string wlFolder = Application.StartupPath + "\\wishLists\\";
string wlPath = wlFolder + selectedProduct + ".rtf";
// Read from the text file and out put the results
try
{ // create directory if it does not exist
if (!Directory.Exists(wlFolder))
Directory.CreateDirectory(wlFolder);
} // create file if it does not exist
if (!File.Exists(wlPath))
File.Create(wlPath).Dispose();
var iStream = new FileStream(wlPath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
var sr = new System.IO.StreamReader(iStream);
var readData = sr.ReadToEnd();
wishListRichTextBox.Text = readData;
sr.Close();
// If the read fails then output the error message in the same section
catch (Exception ex)
wishListRichTextBox.Text = "Error: " + ex.Message;
Writing the file:
private void wishlistTabChanged(object sender, EventArgs e)
if(menuTabControl.SelectedTab != wishListTab){
if (productComboBox.SelectedIndex >= 0)
try
string wlFolder = Application.StartupPath + "\\wishLists\\";
string wlPath = wlFolder + productComboBox.SelectedItem + ".rtf";
var oStream = new FileStream(wlPath, FileMode.Open, FileAccess.Write, FileShare.Read);
oStream.SetLength(0);
var sw = new System.IO.StreamWriter(oStream);
sw.WriteLine(wishListRichTextBox.Text);
sw.Close();

Not certain this is what you're after, but this :
#import the contents of both csv files
$dbexcel=import-csv c:\dbexcel.csv
$liveexcel=import-csv C:\liveexcel.csv
#prepare the output csv and create the headers
$outputexcel="c:\outputexcel.csv"
$outputline="Name,Connection Status,Version,DbExcel,LiveExcel"
$outputline | out-file $outputexcel
#Loop through each record based on the number of records (assuming equal number in both files)
for ($i=0; $i -le $dbexcel.Length-1;$i++)
# Assign the yes / null values to equal the word equivalent
if ($dbexcel.isavail[$i] -eq "yes") {$dbavail="Available"} else {$dbavail="Unavailable"}
if ($liveexcel.isavail[$i] -eq "yes") {$liveavail="Available"} else {$liveavail="Unavailable"}
#create the live of csv content from the two input csv files
$outputline=$dbexcel.name[$i] + "," + $liveexcel.'connection status'[$i] + "," + $dbexcel.version[$i] + "," + $dbavail + "," + $liveavail
#output that line to the csv file
$outputline | out-file $outputexcel -Append
should do what you're looking for, or give you enough to edit it to your exact need.
I've assumed that the dbexcel.csv and liveexcel.csv files live in the root of c:\ for this, that they include the header information, and that the outputexcel.csv file will be saved to the same place (including headers).

How can I connect multiple devices to Mac mini display port? I need to connect a Canon 5D to my Mac and display the result on a VGA video projector. I am using mini hdmi to mini display for the camera. Can I connect the VGA to any other port?

Hi there I am connecting a Canon 5D to my laptop trying to use it as a webcam trough camtwist.
At the same time I need to output the streaming to a videoprojector.
The cam is connected to the mini display port do there is no port available for the VGA cable anymore.
Do I need to use a different port for the projector? Should I buy a video card?
Can't connect the camera via USB as that is too slow and it will freeze.
Many thanks for all your help

I would like to read a file and display the results in a table containing both strings and numbers?

Hi,
I just need a simple way of doing this as at the moment, i read one line at the time containing strings and numbers, whenever i convert this line to an array i loose the strings, if i want to display it, it displays as a group of lines while i would like to display it as a table with column headers. The file is an .xls worksheet.
Any suggestions?
Thanks

Hi,
Look at attach vi.
If this is not what you need please clarify.
With ActiveX you can Open Excel, interact with it (read and write values to cells...
But if you can read it this way, I think it's easier.
Hope this helps,

Running Interactive commands in java and displaying the output.

Hi All,
I'm running a sample code to execute a user defined command (cmd1) and display the results. The output of the command when executed in command prompt is
(1) Executing the command cmd1
(2) Do you want to continue(Y/N)_ <waits for user input>
(3) Based on user input
(Y) Displays the results
(N) Interrupted
But i'm facing problem when i execute the below code. When the results are being displayed instead of displaying line(1) and (2) and then waiting for the input- the code waits for the input and then only displays the results.
O/p
inside output
inside input
y (------ gets the input and then only displays the results).
Executing the command cmd1
Do you want to continue(Y/N)
results
Please help out how to resolve this issue.
Thanks.

Console input is line buffered. This means you only get the first character a line after the newline has been inputed.
The same thing happen if you just type on the console.
I am not aware of any simple way around this.
IDEs get around this by changing the application run so that the input/output is captured as it happens and sent over a socket connection.

How to communicate between Flex and JSP and show the result in an Iframe

Hi all
I am trying to send some data from flex to one HTTPService and trying to show the same response jsp in an Iframe. But unfortunately i am unable to get the responce Jsp's url to set as a source for iframe.
let me explain you clearly...I have a mxml where i am having a text box and a button in the left panel and in the right panel i am having an Iframe to display jsp. So once user enters some value in the text box and clicks button then HTTPservice's send method will be called with text box's content as an arguement. So i can fetch that value from request object in jsp and display the value in jsp. So the problem here is i want display that result jsp in my Iframe. I know that , we need that result jsp URL to display in Iframe . But as i am sending POST request to HTTPservice, i am not able to get the result jsp's URL in flex side.
So i need help desperately from great minds.So anyone of you can give me some suggestions!!!!
Regards

Hi all can some one please give a solution ...Any suggestions would be greatly appreciated
