Define what you expected to happen and what actually happened. I suspect your expectation doesn't match what the documentation promises.

The documentation of SetBkMode says this:

The background mix mode is used with text, hatched brushes, and pen styles that are not solid lines.

Are you using any of those three?

Hello,

I am currently trying to run a vbs-Script the same way I'd run an exe from within my MFC app, so I pass the call to my "test.vbs" to CreateProcess, which unfortunately fails (GetLastError returns code 193). What is a safe way to execute a VBS-Script? If I doubleclick the vbs file in Windows explorer, everything works fine.

You can use ShellExecute to run the vbs file.

ShellExecute(0, "open", "test.vbs", ...

Mr Superman's answer is probably what you want, but if you want or need more control over how your VBScript runs than opening it with ShellExecute (for example, should it have a console window or not?), you could construct a command line to execute it like, using cscript or wscript as the executable and pass your vbs file as a parameter.

For example:

wscript a.vbs would run the VB script without a console window.

cscript a.vbs //X would run the VB script with a console window and attached to a debugger (if there is one).

For what definition of 'add'?

Splitting the task into components:

Load jpg or png - CImage[^] will do that
Adding the two images? As I said, depends what you mean by add
Save the resulting bitmap as a jpg - again, CImage will do that

wenbingao22-Feb-09 22:14

the image I want is made up of a jpg and a png,so "add" means two images become one,jpg is background img,png is the foreground.

what can I do for synthesis two image?

Stuart Dootson22-Feb-09 22:17

You probably want to AlphaBlend[^] the png onto the jpg. You'll need to work out how transparency is indicated in the png file.

You probably forgot to link to the correct library (the sqllite library). Have you done that in your project settings ?

hi.. i've already added the required sqlite3.h header file yet the error messages are not resolved. Can you please help me on that. This is my coding:

// SQLITE1.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <stdio.h>
#include "sqlite3.h"

static int callback(void *NotUsed, int argc, char **argv, char **azColName){
int i;
for(i=0; i<argc; i++){
printf("%s = %s\n", azColName[i], argv[i] ? argv[i] : "NULL");
}
printf("\n");
return 0;
}

int main(int argc, char **argv){
sqlite3 *db;
char *zErrMsg = 0;
int rc;

if( argc!=3 ){
fprintf(stderr, "Usage: %s DATABASE SQL-STATEMENT\n", argv[0]);

}
rc = sqlite3_open(argv[1], &db);
if( rc ){
fprintf(stderr, "Can't open database: %s\n", sqlite3_errmsg(db));
sqlite3_close(db);

}
rc = sqlite3_exec(db, argv[2], callback, 0, &zErrMsg);
if( rc!=SQLITE_OK ){
fprintf(stderr, "SQL error: %s\n", zErrMsg);
sqlite3_free(zErrMsg);
}
sqlite3_close(db);
return 0;
}

A .h file is not a library file, it's a header file. You need to have a *.lib file to be added in your project settings: in the linker category, you need to add the name of the lib file in "Additional Dependencies" or something like that (I don't have VS installed on my PC here so I can't give you the exact location, but search a bit and you'll find it).

I'm using visual c++ for the project and already added the sqlite3.dll file. The same error occurs again. I have no idea where it went wrong..
