Okay, now that I have mastered my single table report, I thought I would plunge into the multi-table report.
But I do have a couple of questions regarding the DataSet design. Do I just drag the tables onto the designer form and that's it? Do I have to worry about the relationships between the tables? Also, I do not require all the fields from all the tables. Can I eliminate some of the fields so the dataset fields more closely match the query? Does it matter one way or the other?
Thus far I just dragged the tables onto the designer and didn't do anything else and surprise surprise my report runs but it is blank. So, besides the above, is there anything else I need to worry about to get this report to run?
Again, any help is much appreciated
Thanks.

You can use Windows' Task Scheduler service to do this (see How To Use the AT Command to Schedule Tasks[^]).
is Windows Services a good way or is there another way around ?
I'd say creating a service is a good idea if you want to run something unattended and without desktop interaction. However keep in mind that if you create a service on your own you'll also be responsible for the scheduler logic. You'll have to decide which solution is most suitable for your requirements.
Best regards

Hey,
I am using a PDF printer.
I am setting the "HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows" Device key to my PDF printer to set it as the default printer so that it is automatically selected when a application prints.
But some applications succesfully recognise the newly set key as the new default printer and others do not, and only see the previous default printer.
Is there another value that i need to check or set for all applications to use the newly set default printer?
Thanks for your help

I'm using code I found on Internet (www.TheScarms.com) to populate/update Excel data from VB.net project. When debugging I'm getting the following error:
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in PRCoverSheet.exe
Additional information: Invalid index.
The code of the part that gives the error is:
'Open the XLS file and activate the worksheet to populate:
Dim strWorkSheetName As String = "MyData"
Dim sbExcelData As System.Text.StringBuilder
Dim aWorkbook As Excel.Workbook
Dim aWorkSheet As Excel.WorksheetClass
aWorkbook = myExcel.Workbooks.Open(strExcelFile)
aWorkSheet = CType(aWorkbook.Sheets(strWorkSheetName), Excel.Worksheet)
' CType(myExcel, Excel._Application).Quit()
aWorkSheet.Activate()
The debugger highlights the following statement:
aWorkSheet = CType(aWorkbook.Sheets(strWorkSheetName), Excel.Worksheet)
What could it possibly be and how can i fix it?
Thank you all in advance

Hello everybody!
I have a trouble with Outlook. The following VB code
set objOLApp = CreateObject("Outlook.Application")
objOLApp.Session.AddStore("c:\temp\test.pst")
perfectly adds new store but how can I get the root folder corresponding to this newly added store? If I were sure that this file is not yet added then I could collect EntryIDs before and after operation and find the difference. But I'm not sure because of statement of work. Is there a way to establis correspondence between root folder and store file name? As far as I know Outlook GUI allows this.
Thanks in advance.

Can I consume a Webservice coded using ASP.NET & C# in a VisualBasic 6.0
application?
I read it can be done using Soap toolkit..but I a dont want to use it as it will be required to be installed on all the machines using that application.
How to do it without using toolKit.
Thanx

Save yourself the aggravation of re-writing the SOAP toolkit yourself and just use it.

Is it possible to change the color of only certin lines in a text box? I am trying to write a cheap game for my senior project and I thought it would be cool to be able to change color of the text if I was getting hit by something to red, and have me hitting the enemy in white. If anyone has any helpful thoughts please email them to me or post them.
Thanks so much
Tommy

You know 'txtSample.ForeColor = vbColorRed' can change your text's color, but all lines. It's impossible to change colors of only certain lines in textbox. I have 2 ways to solve this problem (I often do):
1)I think textbox is not for displaying, it's for inputing. So you should use 2 labels: 1 for you and 1 for the enemy. When you are getting hit  , your label red, enemy's label white , contrary...
2)You can use a RichTextBox:
rtbSample.SelText.ForeColor = vbColorRed
but it's not my favourite because the RichTextBox control is very complex .
I post this reply on a computer without Visual Basic installed, so that I can't test the code. If you don't like my answer or don't understand , reply me, I will find another way (I pay attention to this problem too!)

Does anyone know how to format a date to October 02, 2004 when the incoming data is 10/02/2004? (Using Basic Syntax not Crystal Syntax)
The following code works in vb.net but I can't figure out what the correct syntax would be in the formula editor.
Dim dteSDate As Date = csvDataRow.Item("SDATE")
Dim strFormatSDate As String = Format(dteSDate, "MMMM dd, yyyy")")
All help is greatly appreciated!
