MapForums

Hi,
if i run my mappoint app on xp all works fine. On Vista, i can create an instance of the ocx but i it throws an exception when i try to load a NewMap.

Some code right here:
delegatevoidInitializeOCXDelegate(AxMappointControl ocx);
privatevoid InitializeOCX(AxMappointControl ocx)
{
if (!ocx.InvokeRequired)
{
ocx.Dock = DockStyle.Fill;
ocx.Visible = true;
ocx.Appearance = 0;
ocx.BorderStyle = 0;
ocx.NewMap(MapPoint.GeoMapRegion.geoMapEurope); //Hier wird die Karte definiert auf der gearbeitet wird
}
else
ocx.Invoke(newInitializeOCXDelegate(InitializeOCX), ocx);
}

I got the strange behaviour that on xp InvokeRequired = false, but on vista sometimes (don't know for sure)InvokeRequired = true, when i try to debug the invoke call the debugger ignores it (don't know if it is executed, it just moves on).

Has someone ever had the same issue on a vista pc or has any idea?

Best Regards

Hi, like in another post it's the NX_COMPAT flag set in your exe by
vs2008.

....tools/.../vsvars32.bat (so editbin.exe finds its dlls - can't remember exact path)
editbin.exe /NX_COMPAT:NO "file.exe"

solved the problem for me

good luck

Little backgroundknowledge,
since end 2004/early 2005 intel processors have a nx(not execute) bit .
AMD had that already a little earlier.
However, this enables the DEP of WindowsXP SP2 and higher (Vista).

My current Notebook is from early 2004, therefore the processor has no
nx bit -> all works fine even with set nxcompat bit in my exe

On the other machines, mostly core2duo laptops and vista the nx bit
takes action and prevents the execution of the atl 7.1 ... i can get
the structure of the ocx (strange to me) but all calls get rejected.

The only solution is to shut down dep (admins will kill you) or turn off the switch in your exe.

thanks for the feedback

I have follow the steps above, but now I receive the following error message when I try to load a new map:

"Your registry settings for this application were not copied correctly. to correct these settings, run setup again for this application from the location where you originally installed it."

Any ideas?

Thanks & regards,
