How to work on multiple columns in a listbox? Let say, I want two columns, Name and Roll should be displayed two columns in the listbox, values are stored in the database "student".
|
|
|
|
|
Apparently, I read recently that .NET does not support multiple columns in a listbox.  I was trying to accomplish the same thing when I read about the this.
|
|
|
|
|
But there is a property Multicolumn with Listbox.
What is this ??
|

|
|
Sorry, my mistake. I was thinking of the combobox.

Hello all,
I need to render multiple Reporting Services reports into a single PDF for output. Each report will retain its own headers and footers.
Current: (3 PDFs)
---------------------------------
Cover Sheet (1 page)
Sales Report (2 pages)
Accounting Report (2 pages)
Needed: (one PDF)
---------------------------------
Cover Sheet - Page 1
Sales Report - Pages 2 and 3
Accounting Report - Pages 4 and 5
Currently, I am using SOAP to render each individual report to PDF. My application allows users to choose which RS reports they want to output. Obviously, since there is no way of knowing which they will choose, I cannot solve this using RS.
3rd Party tools that require purchase ($) are totally out of the question for me, due to budget constraints. Anything free is good.
Please help!
Thanks very much.

I am making my own browser using Mozilla's ActiveX controls and I am having some trouble figuring out how to let someone set a homepage. i don't know how to work with writing to files and reading from them. someone please help me.(i'm using VB.NET)
OH! I would also appreciate any help on the URL textbox. Here is a situation:
While using my browser, i type in "www.google.com" and hit "go". I click on "news". i would like the address in the textbox to change automatically to "http://news.google.com/nwshp?hl=en&gl=us" instead of staying "www.google.com" how the heck do i do this?
Thanks

I have a loop for a datagrid that shows all the amount rows added together in the caption.text of the datagrid. now i am going to change the loop because i dont need to add the rows, i need to subtract them. i know how to do that, but my question is that i have a textbox(textbox6) for which the user will need to enter a balance to show in the caption.text before the loop can subtract anything. any tips will be greatly appreciated.
this is what i have.
<br />
Dim t6 As Object<br />
<br />
t6 = TextBox6.Text<br />
For Each t As String In TextBox6.Text<br />
Amount += t<br />
Next<br />
<br />
Me.DataGrid1.CaptionText = "Current balance $" & t6.ToString()<br />
it is acting wierd. if i input 7 in the textbox then the data grid recieves only an addition of 1. if i input 9 it gets an addition of 4.why

Sorry, but I dont get what you are trying to do...
You assign the Text of the textbox to the object variable t6 and print it out at the end. But in the loop you are only adding (I thought you want to substract something) values to the variable Amount.
And what is For Each t As String In TextBox6.Text supposed to do in your opinion? I dont think thats what you are really trying to perform...

I have an application where I first load a vb.net app that is going to run in the background. That app then starts another vb.net app that is the user interface (UI). Is there anyway I can send a message (or something) from my UI app to my background app so it can then start a process?
If so, how would that be done?

Hi I am trying to call a Function from a Sub routine that basically does a WMI check and puts the results into a Variable.
Then from the main Sub routine Display the variable in the HTA app.
I'm sure the WMI function works ok but I'll be damed if I can get the variables to be displayed in the HTA app.
Here is a sample of the code Iam running, any help would be appreciated. Thanks
' ********* GET OS FUNCTION **********
Function GatherInformation
On Error Resume Next
Set objWMIService = GetObject("winmgmts:\\" & sComputer & "\root\CIMV2")
Set colItems = objWMIService.ExecQuery("SELECT * FROM win32_OperatingSystem", "WQL", _
wbemFlagReturnImmediately + wbemFlagForwardOnly)
For Each objItem In colItems
strOperatingSystem_InstallDate = objItem.InstallDate
strOperatingSystem_Caption = objItem.Caption
strOperatingSystem_ServicePack = objItem.CSDVersion
strOperatingSystem_WindowsDirectory = objItem.WindowsDirectory
strHTML = strHTML & objItem.Caption
strHTML = strHTML & strOperatingSystem_Caption
Next
Set objWMIService = Nothing
GatherInformation = True
DataArea.InnerHTML = strHTML
End Function
' ********* END OS FUNCTION **********
' ******* PUT HTML IN THERE ***

strHTML = strHTML & "WMI Connection Successful" & "

Get rid of the wbemFlagReturnImmediately flag. It'll cause the ExecQuery call to retrun immediately, without waiting for any actual data to come back. You're variables are then getting assigned blank strings because, obviously, you didn't wait for the ExecQuery call to return any data!
[EDIT]
Replace it with the wbemFlagReturnWhenComplete instead. It'll cause the call to block until some actual data is returned.

Thanks for replying but I tried both getting rid of the wbemFlagReturnImmediately and also trying replacing it with wbemFlagReturnWhenComplete but both still did not help in me being able to display any data from the variables. Any other ideas?
