I tried : regsvr32.exe C:\Documents and Settings\Alexis\Bureau\Fil
but i got this message error : LoadLibrary("Path to dll") has failed, the specified module could not be found.
I don't really know where is the driver of mysql... but i know that i need the QtSql4.dll
It is for mysql uses.
Hi,
Some things come to mind
- the application is looking for that .dll in a specific place
- the .dll is registered more then once in registry
- this .dll is dependent of another .dll (use dependency walker to find out if that's the case - http://www.dependencywalke
- according to http://support.microsoft.c
- go to Control Pannel / Administrative Tools and start "Data Sources (ODBC)". Enable tracing. See if in the logs there is some aditional info about the error
- download the MDAC checker to see if no ODBC driver is corrupt (http://www.microsoft.com/
tdor
If I look with dependency walker everything is in my project folder on every computer
but when I look out my program with pview, on my computer there some dll that are loaded in the Qt folder.
If I'm not working on my computer, the dll that were in the qt folder are not even mention... I think it's these dll that my program need, but how to attach them to it.
what are ODBC driver... I think I have a link with Visuall...
my compiler is mingw by the way
Unfortunately I do not have experience with mingw
Try to put in the folder (on other computer) all the dlls that are missing from the QT folder
register then with regsvr32
About the ODBC -> http://en.wikipedia.org/wi
Thanks man for your help, Ifinally solved my problem after a few day of hard work !!
It's just that you need to specified to your application where you put the driver.
I created a folder named plugins, and add to it the containt of qt plugins folder
The Pview really help me and this web page too, http://doc.trolltech.com/4
You just need to go on Pview chack all the dll that are not in the project folder and them.
You have no had this function with the pash of your plugins: QCoreApplication::addLibra
If you have any question just ask me by this post ! or alexj13@videotron.ca

Hello tinzaker,
try to register the drivers on the "away from home" machine
from start menu/run
regsvr32.exe "path to the drivers" (with the " if you have spaces in the path)
ex: regsvr32.exe "c:\my app\my project\needed_dll.dll"
Regards,
tdor
