On Windows NT Kernels (NT, 2000, XP, 2003, Vista, ...) it's proper to CMD, not Command.com.

Anyone know how to solve this warning problem ?
"Warning 1 Function 'report1' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used."

There are paths in your function that will not set and return a value. For example:
Public Function ReturnExample(ByVal i As Integer) As Boolean
If i < 100 Then
Return True
End If
End Function
This will generate the very same error because if i is greater than or equal to 100, no return value will be set, but the function will terminate. Possible fixes would be:
Public Function ReturnExample(ByVal i As Integer) As Boolean
If i < 100 Then
Return True
Else
Return False
End If
End Function
or
Public Function ReturnExample(ByVal i As Integer) As Boolean
Dim rv As Boolean = False
If i < 100 Then
rv = True
End If
Return rv
End Function
What you do depends entirely on your code and what you expect it to return in ALL cases.

Hi all,
I have some screens in the WinForms app I'm working on which have datagrids with long column headers (such as "Cumulative % of Injection Demand" and I want to be able to show these in their entirety by somehow having the header row high enough... it doesn't need to be dynamic - I just want to do something like say "dataGrid1.HeaderRowHeight = 50". Since it can't be done via the normal datagrid properties (I can't beleive how much basic stuff M$ left out of the WinForms datagrid!!) what would be the best way of doing it? (Any examples or links would be appreciated - I didn't find much from Google)
TIA for any help/advice,
Mike

This is a huge pain to implement. But, you can use a library written to do this for you right here[^] on CodeProject. It's a C# library, but it'll add the support you want.

Thanks Dave - that worked very well... except for grids that have sortable columns where the sorting icon (the little triangle) seems to screw the rendering up. Anyway, for one of two of the grids I need it on I don't need sorting so that's cool.
Cheers,
Mike

 Well, I didn't say it was perfect!
You could always use VB.NET 2005! Good support for this is built right into the new GridView!

Does anyone know whether its possible to turn off background compilation. I am sure its making my Visual Studio 2005 solution unresponsive.
|
|
|
|
|
From what i read[^], it's not possible to turn of the BC.
"While you can't turn off the background compiler..."
Why do you think that it's the BC that makes the solution unresponsive?

Perhaps i've got it wrong and its not background compilation that is the issue. I am running visual studio 2005 on a solution that is upgraded from VB6 and has a vast quantity of errors. Hence my suspicion...
The fact that you can't switch it off, kind of suggests that its never an issue to worry about. If i get to the bottom of it i will let you know.
Thanks

I would recommend that you DON'T use the VB6 Upgrade Wizard. It puts alot of code in to simulate the way VB6 did things, which can be pretty inefficient when compared to correctly rewritten code in VB.NET.

Can someone provide a checklist on different runtime errors that can occur during drive / directory / file operations ( this is general for any language ) .

You'll have to built that yourself. Lookup each method that your going to use (like Directory.GetDirectories[^] for instance), and look at the Exceptions that each can throw.

Standard question #1:
What do you mean by "not working"?
---
b { font-weight: normal; }
|
|
|
|
|
when i try to run it exception apper.InvalidOperationException. it highlighted the conMydata.open() and said ==> The ConnectionString property has not been initialized.
how could i solve it?
|
|
|
|
|
You have forgotten to put the connection string in the configuration file.
---
b { font-weight: normal; }
|
|
|
|
|
i've put the connection string in the webconfig file.but the same error still appear.Is there any place else should i put it?pliz man help me.how should i initialize the connection string?
|
|
|
|
|
Set a breakpoint on the line that grabs the connection string from the config file and VERIFY that it indeed does return what you think it does.

Hello,
I want to launch a program when a user login from a service (running as a system service). Of course in need the instance of this program to be visible for the user who just logged in.
I manage to check if the user is logged or not , but i'm not able to launch a visible application (a third party program) for the user...
Thx in advance,
