Windows 7 rundll32.exe problem executing a dll

[Dominus]

I have a Tablet (old HP/Compaq TC1100, 1.2 GHz, 1GB RAM). After some fiddling around with old drivers everything is running fine.
The TC1100 comes with a software called qmenu with which you can toggle the wireless on and off. That is working.
To do that via a script or assigning a button to it under XP one could execute the dll of that program via rundll32.exe.
In the directory of the program executing "rundll32.exe qsupport.dll,WirelessToggle" would turn on/off the wireless device.
Now under Windows 7 (Professional Upgrade) nothing happens. I see the spinning cursor for a moment and then it's done. No trace of function, wireless stays the way it was. The Eventlog doesn't show anything in regard of that (or anything at the time of execution).

Does anyone have a clue what is going wrong here? Other rundll32 commands, for eaxample with shell32.dll are working.

It seems like you are encountering an issue with executing the rundll32 command to toggle the wireless device on and off using the qmenu software on your HP/Compaq TC1100 Tablet after upgrading to Windows 7 Professional. The fact that the command runs but does not have any effect suggests there might be a compatibility issue or a change in the behavior of rundll32 in Windows 7. Here are a few troubleshooting steps and suggestions you can try to diagnose and potentially resolve this issue:

Troubleshooting Steps:​

1. Compatibility Mode: Try running the command in compatibility mode. Right-click on the rundll32.exe file, go to Properties, navigate to the Compatibility tab, and check the box for "Run this program in compatibility mode for" and select Windows XP. Apply the changes and try running the command again.
2. Run as Administrator: Right-click on the Command Prompt or whatever method you are using to run the command and select "Run as Administrator" to ensure there are no permission issues causing the command to fail.
3. Event Viewer: Check the Event Viewer for any related logs or errors that might provide more information on why the command is failing. Look for entries around the time you tried to run the command.
4. Dependency Check: Ensure that all the necessary dependencies for the qmenu software are present and correctly installed on your Windows 7 system. Some DLLs might be missing or incompatible with the new OS.
5. Update Drivers: Check if there are updated drivers or software available for your HP/Compaq TC1100 Tablet that are compatible with Windows 7. Installing updated drivers might resolve the issue.
6. Alternative Methods: If the rundll32 method continues to fail, consider exploring alternative methods to toggle the wireless device. This could involve using third-party software or scripts specifically designed for Windows 7.

   Scripting Alternative Command:​

   Instead of relying on rundll32, you can also create a simple script using other methods to toggle the wireless device. One common method is to use PowerShell commands to enable or disable network adapters: To enable the wireless adapter using PowerShell:

   Enable-NetAdapter -Name "YourAdapterName"

   To disable the wireless adapter using PowerShell:

   Disable-NetAdapter -Name "YourAdapterName"

   You would replace "YourAdapterName" with the actual name of your wireless adapter. Try these suggestions and let me know if any of them help resolve the issue with toggling the wireless device on your HP/Compaq TC1100 Tablet running Windows 7 Professional.
