Retrieving ProductVersion from stringtable

[john0532]

How do you get the ProductVersion, FileVersion, etc. from the string table?

Use the FileVersion API's, see GetFileVersionInfo(..)

I've created a little object wrapper for this; I hope it wraps correctly

First the Header file:

// Declarations for Version from Version Resource class
// Written by Frank Solomon 2000
//
#ifndef __ver_h
#define __ver_h

#include <windows.h>

namespace fss {

class VersionResource {
UINT VLen;
LPVOID VBuf;
char VString[1024];
char VCopyright[1024];
char VProduct[1024];
public:
VersionResource();
const char *c_str() const;
const char *copyright() const;
const char *product() const;
const char *version() const;
};

} // namespace fss

#endif //__ver_h

Then the .cpp file:

// Definitions for Version from Version Resource class
// Written by Frank Solomon 2000
//

#include &quot;ver.h&quot;

namespace fss {

VersionResource::VersionResource() {
HRSRC hrV = FindResource(NULL,&quot;#1&quot;,RT_VERSION);
if(hrV == NULL) {
throw;
} else {
HGLOBAL hgrV = LoadResource(NULL,hrV);
if(hgrV == NULL) {
throw;
} else {
LPVOID pV = LockResource(hgrV);
if(VerQueryValue(pV,&quot;\\StringFileInfo\\040904b0\\FileVersion&quot;,&VBuf,&VLen)) {
if(VLen > 0 && VLen < 1024) {
wsprintf(VString,&quot;%s&quot;,VBuf);
} else {
throw;
}
}
if(VerQueryValue(pV,&quot;\\StringFileInfo\\040904b0\\LegalCopyright&quot;,&VBuf,&VLen)) {
if(VLen > 0 && VLen < 1024) {
wsprintf(VCopyright,&quot;%s&quot;,VBuf);
} else {
throw;
}
}
if(VerQueryValue(pV,&quot;\\StringFileInfo\\040904b0\\ProductName&quot;,&VBuf,&VLen)) {
if(VLen > 0 && VLen < 1024) {
wsprintf(VProduct,&quot;%s&quot;,VBuf);
} else {
throw;
}
}
FreeResource(hgrV);
}
}
}

const char *VersionResource::c_str() const {
return (const char *)VString;
}

const char *VersionResource::version() const {
return (const char *)VString;
}

const char *VersionResource::copyright() const {
return (const char *)VCopyright;
}

const char *VersionResource:roduct() const {
return (const char *)VProduct;
}
}

And Finally here's an example of how it's used (vermain.cpp):

//Demo of VersionResource Object
//Be sure to add version.dll to the linker input for this project
//Also be sure to link in a version resource!!!
#include <iostream>
#include &quot;ver.h&quot;

using std::cout;
using std::endl;
using fss::VersionResource;

int main(int argc, const char *argv[]) {
VersionResource V;
cout << &quot;The Current version is: &quot; << V.c_str() << endl;
}

Hope that's helpful.
