Problem using MsiGetProductInfo for retreving the product version

V K 226-Jun-09 2:48

I am using the below code snippet for retreving the Product version . This works fine when I write this in a sample application. I am retreiving the correct product version Eg. "10.9.8". But when I integrated this code snippet with my project code. then str string in below code gives me return value as "?#@!" Can I know what could have been the problem.

CString GetInstalledIntouchCEVersion()
{
UINT returnCode;
char pProductCode[39]={0};
//char lpVersion[50] = {0};
LPSTR str;
DWORD cchVersionName;
str = new TCHAR[50];
// Here Guid is MSI product upgrade code for InTouchCE
returnCode = MsiEnumRelatedProducts("Our Product Code",0,0,pProductCode);
if ( ERROR_SUCCESS == returnCode )
{

UINT ret = MsiGetProductInfo(pProductCode,INSTALLPROPERTY_VERSIONSTRING,str,&cchVersionName);
}
return str;
}

I see you are 'returning' str with no regards to what MsiGetProductInfo() returned. Unsure | :~

Can you check the return value?

Program not giving desired output

#include <stdio.h>
#include <stdlib.>
#include <string>
main()
{
char s[80];
int i=0;
FILE *fp;
fp=fopen("POEM.TXT","w+");
if(fp==NULL)
{
puts("Cannot open file");
exit(1);
}
puts("Enter any string");
while ( strlen(gets(s)) >; 0 );
{

fputs(s,fp);
fputs("\n",fp);
}

fclose(fp);

}

This prog should write the given output to the text file. But inspite of not giving any errors the text file remains empty!!!

Take a look at the code you've posted! It is not properly formatted and worse yet some parts are not visible. Please "edit" your post, select all the code and click the "code block" formatting option.

This line should be

while ( strlen(gets(s)) > 0 )

i.e. without the semicolon at the end.

You may use ShellExecute()[^] and that will open an RTF file (or any other file) with the default application registered to handle it.
