Re: [sqlite] System.Data.Sqlite problem
And don't you wish Microsoft and other's could spit out intelligent error
messages like:
"64-bit application trying to load 32-bit DLL".
I ding my students whey do stupid stuff like:
FILE *fp=fopen(filename,"r");
if (fp == NULL) {
fprintf(stderr,"Cannot open file\n");
}
Instead of
if (fp == NULL) {
perror(filename);
}
Which actually tells you what the problem is, permissions, not existing, etc
It would be so simple for the DLL manager to be able to do this. But it's the
same as Microsoft's old error message of "Cannot load dll". To which I always
screamed "what DLL and why not"
You're just seeing the new version of it.

This is the expected behavior, let me explain why.
First off, I'm going to assume you downloaded the non-mixed-mode packages.
They both include a native "SQLite.Interop.dll" (for the appropriate
processor architecture) that contains the SQLite core. They also include a
pure managed "System.Data.SQLite.dll" (marked as "pure IL" in the CLR
header).
When any .NET application marked as "pure IL" runs on 64-bit Windows, it
will run as a 64-bit process. Similarly, if you run that exact same
application on 32-bit Windows, it will run as a 32-bit process. A 64-bit
process cannot load a 32-bit DLL.
Therefore, the "test.exe" program starts as a 64-bit process and then
attempts to load the 32-bit "SQLite.Interop.dll", which raises the
BadImageFormatException.

[sqlite] System.Data.Sqlite problem
Hello, I've just downloaded the 64 bit + 32 bit binary zip versions of System.Data.Sqlite version 1.0.74.0. I unzip and then run the test.exe program. The 64 bit version works like a charm but the 32 bit version unfortunately does not. The error message given by test.exe is given at the end of the message. The BadImageFormatException might suggest a bad download... so I've re-downloaded a number of times and the result with the 32 bit version is always the same. I am running Windows 7 64 bit with VS2010 SP1 installed so all of System.Data.Sqlite's dependencies are installed. Any ideas what's going on?
