Application Freezes Or In Hang State
Hi guys
How can i detect if an application is in hang state or the application freezes?
I have this code below to check in my application checker. It checks if an application is in hang state and it closes the application if it is. But for a reason it does not close an application if it is in hang state.
Abort Hang Statement Code:
lReturn = SendMessageTimeout(lHwnd, WM_NULL, 0&, 0&, SMTO_ABORTIFHUNG And SMTO_BLOCK, 60000, lResult)
For i = 1 To lvAppList.ListItems.Count
lHwnd = lvAppList.ListItems.Item(i).SubItems(4)
lPid = lvAppList.ListItems.Item(i).SubItems(1)
If lHwnd <> 0 Then
lReturn = SendMessageTimeout(lHwnd, WM_NULL, 0&, 0&, SMTO_ABORTIFHUNG And SMTO_BLOCK, 60000, lResult)
If lReturn Then
Label5.ForeColor = vbBlue
Else
msgbox "Application Freezes"
lvAppList.ListItems.Item(i).SubItems(4) = lHwnd
lvAppList.ListItems.Item(i).SubItems(1) = lPid
End If
End If
Next

FileCopy Method And Application State?
hello vbCity!
I have 2 questions. Are we allowed to post 2 in one post?
I am using fso file.copy to copy a file from cd to hard drive(very slow). I want to use vb's filecopy function but I am getting an error (runtime '76', path not found) I believe because my file is read-only. Here's my code:
Code:
For Each CDFile In CDFiles
FileExists = InStr(1, UCase(CDFile.Name), ".MDB")
If FileExists <> 0 Or FileExists <> Null Then
SourcePath = CDDrive.Path & "" & CDFile.Name
'Instantiate the file object
Set CDFile = FSO.GetFile(SourcePath)
DestPath = App.Path & ""
'Copy the file
' SetAttr SourcePath, vbNormal
' FileCopy SourcePath, DestPath-----------------This method is faster-------------
CDFile.Copy DestPath, True
'Change temp file attribute from readonly to normal
SetAttr DestPath & CDFile.Name, vbNormal
'I'll do something else here.
'Delete the temp file
Kill DestPath & CDFile.Name
Exit For
End If
Do you think that the Read-Only is what is giving me the error using filecopy? This works fine using the fso file.copy.
Any solutions?
Here's my second question:
How can I find out if my app is in the copying process so I can display a progress bar to my user. This way they can see that the app is doing something.
While app is copying the file
show progress bar and fill it up
wend
Something like that or close I think....
Thanks VB City!!!

State Management In A Windows VB 6.0 Application
Hey folks.... do you know of any state management techniques in VB 6.0, for example if you wanna keep the state of the controls around after saving the forms and have all the differnent forms in my application access the new state...what's the best way to do that...If you can tell me about a couple of ways to manage state, that would be great. I'm a web programmer so never really dealt with state issues on a windows VB 6.0 application.
Thanks

HTML Help System And VB Application
I have made a HTML help system for my VB application. When I press F1, in my application, the help window opens and everything is fine.
But...
I want to have popup help window for each field (text control) in the form. Following instructions I made [MAP] and [TEXT POPUPS] sections.
When the text control has the focus, after I press F1, I have an error window with message: "HH_HELP_CONTEXT called without a [MAP] section".
What is the problem?
Thank you for any help.
Running VB Application On System Without VB?
All of my VB applications have been done for fun and for my own use. I compile & run them from the Visual Studio environment.
Some friends of mine have seen a few of my applicatons and would like to run them on their systems.
I have never atempted to Package an application for use on another system. Will the Package & Deployment Wizard do a good job? I am going to try to hack the Wizard first and then look at the MSDN Help Files I have.
Any hints at how to get started would be appreciated.
What if the Target system runs Windows 95, XP, 2K, or another OS instead of Windows 98 SE (My OS).? Will there be problems?
What about different Video controllers? I assume that this will not be a problem. Will running at a different resolution or color mode cause a problem? I intend to experiment a bit with this on my system, but would welcome advice.
If I experiment on my system in the Visual Studio environment and the applicaiton seems to work okay, will this indicate that the deployed application will also work okay with changes in screen resolution & color mode?
I hope at least some of the above can be answered, and I will appreciate any advice I can get. I like to hack, but do not really want to reinvent the wheel.

Application Patch System
Does anyone know of a script in VB6 that would update my applications? Example: Lets say I have Client A in Seattle WA, and I am in Not Seattle WA. I write an update to the software and want to push it out to Client A without physically going to Client A's place of business and copying over the exe file. I know it can be done, but I am lacking the understanding. Can anyone shed some light?

Dll In System And In Application Folder?
Hi,
Anyone knows where can I read about how Windows (as many versions as possible... NT; 2000; etc) deals with system dlls?
I think that windows95 searches for them in the application directory and if this directory doesn´t have the dll it will use that in system directory...
I would like to have sure about this topic.
Thank you

System Tray Application Problems
Hi,
I am working on a programme, and I have been asked to make it a background application, i.e. when minimised, it runs in the taskbar.
I have used microsoft's solution:
http://support.microsoft.com/kb/176085/EN-US/
The programme runs, and it can be minimised to the system tray.
Unfortunately, the
nid.uCallBackMessage = WM_MOUSEMOVE (where WM_MOUSEMOVE = &H200) does not seem to operate correctly in this application. This in turn causes the failure of the Form_MouseMove sub to be called - the application cannot be re-maximised from the system tray once it has been minimised there.
I tried Microsoft's code in a completely new application, and it worked fine.
What I would like to know is, what could be causing the programme to ignore this command, and how can I overcome this - is this a known issue?

Adding this to the Form_Load event adds the icon into the tray:

AddTrayIcon Me.hWnd, Me.Icon, Me.Caption
BUT, here is my problem. I am nearly sure this is the module I used when I added in code to minimize my application to the system tray icon so it's not on the taskbar, but I have forgotten the code. To clarify, I want to minimize my app to the system tray by clicking the minimize button on the form : _ [ ] X
Thanks all in advance.
Calling An Application Through A System Service
Is there a way to run application B.exe through A.exe, which is executed by a system service (NT/2000)? The problem is my call shell comand works on Win95/98/ME, but on NT and 2000, the service which kicks off A.exe does not have permission to spawn B.exe. Can you specify the permission in the code? Hope this makes sense.

Minimize Any Application To System Tray
Hi,
I am working on a program to minimize any program to the system tray. i.e. outlook...word or any program. Basically I want to remove the minimized application from the task bar and put an icon in the system tray.

Thank you in advance!
