[RESOLVED] Works in compiler, not when compiled

[bail3yz]

Hi, this chunk of code works when I run my project from withing VB, but once i compile it doesnt work

For i = 0 To numofItems - 1
    If SendMessage(listhwnd, LVM_GETITEMSTATE, i, LVIS_FOCUSED) = 2 Then
        curPosition = i
        Exit For
    End If
Next i

basically it goes through the list and checks which item has focus.. and changes curposition to that item on the list

also, I have checked everything i can think of numofitems does equal the correct value all the time

so i am pretty sure

If SendMessage(listhwnd, LVM_GETITEMSTATE, i, LVIS_FOCUSED) = 2 Then

somehow doesnt work once its compiled, any idea why?

[bail3yz]

is it possible that a different version of user32.dll is being used when its runningin the compiler and when its compiled?

I checked the values of everything, in both situations everything is the exact same... except curposition

[bail3yz]

Nope thats not it, i downloaded user32.dll and renamed it and had the sendmessage function use that dll.. same problem

Is it a ListBox control? it is in your App or external App?

[bail3yz]

it is in an external app, and its a SysListView32 (same problem occurs for ListView20WndClass, I believe they are pretty close to the same or something?)

also i tested my code on numerous different external applications, and everytime its the same problem, if its running within visual basic it works, but once compiled that one line always equals 0 so i can never figure out which line has focus

[bail3yz]

Here I made an example, this example doesnt use an external app but with this code teh same problem occurs.

I will upload the code and my compiled copy, and youll see what i mean

First open the EXE.. select an item on the list view, and hti the command button..itll say Selected item: 0 (well it does for me)

now open the project in VB and run it from VB.. do the same thing and itll give you the proper #

Problem solved, in project properties, I changed the compile option to compile to P-Code...

[bail3yz]

can anyone tell me why it works in pcode and not native code? also, I read that pcode is easier to decompile, is this true?

If possible I'd like to get it to work in native code.

yes it is easier to decompile back into vb. But that's about it. And maybe you've discovered a bug in vb. Have you any of the patches installed? There are patches for vb6.

[bail3yz]

Yup, I have VB SP 5 I believe, I just tried to install VB SP 6.. but it says "install was not completed successfully" and doesnt provide anymore info ahha

Did you get the SP 6 download from Microsoft's site?

I've never had an issue with installing that.

I Thing this question is answerd and Resolved in Classic VB http://www.vbforums.com/showthread.php?t=488348

it has duplicated.

Ya hack i did, I am not worried about that tho, I bet it has something to do with me running windows 64bit

This is a distinct possibility.

[Lord Orwell]

i run win 64-bit and yes patch installs can fail on it.
