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,

Is your service tagged for "Allow service to interact with Desktop"? If not, you won't see a thing.
Start/Programs/Administrative Tools/Services. Double click your service to open its properties. CLick the Logon tab, make sure the logon account for the service is the Local System account, then you can enable the "Allow service to interact with Desktop" option.

does any one have a tempature converter already made up, if so could you send me the code for it
|
|
|
|
|
1. In what way do you want to convert temperature? Is it the classic Calcius/Fahrenheit conversion?
2. This sounds very much like a school assignment. Is it? If so, you should do it yourself. If you get stuck you can certainly ask for help, but don't expect to get the entire solution handed to you.

sorry should have been more detailed, yes school assignment, I don't want to cheat and use someone else code, I want to see how it it done, if it makes whomever post it to leave some stuff out of code thats cool, I will figure it out, I just don't have alot of time between work and stuff. If no one posts one that cool too. I don't want the whole solution. Just need one that you put first name in last name and then temp to be converted to celcius.

Hi all,
I have this simple piece of code:
Set app = CreateObject("CrystalRuntime.Application")
set report = app.OpenReport("r1.rpt", 1)
report.Save "out.rpt"
The 'Save' method gets STUCK and hangs my machine.
This only happens if the input report has a GRAPH in it. If I delete the graph, the Save method works!
What is going on?
I'm using CR XI release 2, by the way.
Thanks

Hi guys,
So I'm trying to code a sample application for a fingerprint scanner that I recently bought from supremainc.com. Now the sample they provided alongwith is in VB6. I've been successfully able to convert most of the code to VB.NET. The part upto capturing an image is working fine. But when it comes to verification, the old VB6 code uses the VarPtr function - which isn't there in .NET anymore.
Now testing the sample application won't be possible for any of you - coz you'd need the actual device to get it working. But still I'm including the code for both VB6 and .NET here - at least looking at it might help.
Searching for a VarPtr replacement, I came across this code from PlanetSourceCode
===========================================================================
Public Function VarPtr(ByVal o As Object) As Integer
Dim GC As System.Runtime.InteropServices.GCHandle = _
System.Runtime.InteropServices.GCHandle.Alloc _
(o, System.Runtime.InteropServices.GCHandleType.Pinned)
Dim ret As Integer = GC.AddrOfPinnedObject.ToInt32
GC.Free()
Return ret
End Function
===========================================================================
The VB6 code contains this segment:
===========================================================================
Private EnrollTemplate(383, 9) As Byte
.......
.....
Dim Buffer(9) As Long
............
For i = 0 To 9
Buffer(i) = VarPtr(EnrollTemplate(0, i))
Next i
===========================================================================
So I used that in my VB.NET application - and am calling the routine this way:
===========================================================================
Private EnrollTemplate(383, NUM_RECORDS) As Byte
............
Dim Buffer(10) As Integer
...............
For Counter As Integer = 0 To NUM_RECORDS - 1
Buffer(Counter) = VarPtr(CType(EnrollTemplate(0, Counter), Object))
Next
===========================================================================
But it doesn't seem to have the same effect - so my verification is failing.
Also as per the discussion in this thread: http://www.vbcity.com/forums/topic.asp?tid=121051 I've converted the Long variables in the VB6 code to Integer for VB.NET. The code samples (full) I'm talking about can be found attached to the vbCity thread, as the posts here don't permit attachments.
Please find both versions of the project included as .zip attachments. Kindly take a look at them and see if any of you can spot what's going wrong. I know it's difficult to do so - without the code actually running.. but still.
In case you want to look into the Scanner SDK API calls, I'm including the API documentation too in form of a .PDF file.
Any help will be greatly appreciated. Please check out the discussion in the vbCity thread first and go through the code files.
Best Regards & Thanks,

Hi Guys!! Im trying to Make a Bittorrent Client in VB.Net 2005. I want to run the main form of my Project on a Thread and for that i have started my Project with a Module. The Module calls the Form in its Main() function.
What i wanted to do was to create a thread an load the main form in this Thread so that my Main Form runs in the Background. How do i achieve this. The Following code doesnt seem to work:
Dim myThread as new Thread(new ThreadStart(AddressOf MainForm.Load))
myThread.Start()
The Error is that i cannot call the load event inside ThreadStart. So i Dont know what to write after 'AddressOf' so that my Main Form gets Loaded and it runs when the myThread.Start() method is Called.
If anybody know what to do, Plz write back to me. Thank You!!
Devraj Raut!!!
