I'm trying to learn how to take a screenshot using winAPI and c++.
this is what I have done so far.
Code:
#include <Windows.h>
#include <iostream>
using namespace std;
int main() {
HDC hScreenDC = GetDC(NULL);

I've read up on .bmp files on wikipedia and am currently attempting to make a function that can export a .bmp file of the screen of my programs. I've already begun work on it but it isn't working. The code I have so far is:
typedef char Byte;
typedef int Byte4;
typedef short Byte2;
struct BMP_Header {
[Code] ....
My problems are that when less then the required amount of bytes is needed to store a value in the file, the 00 bytes are skipped (Ex. The file will contain 42 instead of 42 00 00 00), and the Pixels are stored as nothing but 0D ( every value intended for storing pixel data is 0D ).
I want to take screen shot and save it in any image format like jpg, bmp, ppm or any other .

CALENDAR_DLG DIALOG 0, 0, 186, 95
STYLE DS_3DLOOK | DS_CENTER | DS_MODALFRAME | DS_SHELLFONT | WS_CAPTION | WS_VISIBLE | WS_POPUP | WS_SYSMENU
CAPTION "Calendar"
FONT 8, "Ms Shell Dlg" {
CONTROL "", CALENDAR, "SysMonthCal32", WS_VISIBLE, 0, 0, 186, 95

My call back function is

switch(uMsg) {
case WM_INITDIALOG: {
} return TRUE;

DTN_DATETIMECHANGE is not being called ? What is UMSG equal to when a date is changed in the calendar?
I want to pass some parameters to a dialog. I am trying to pass a struct as LPARAM in CreateDialogParam. How to access this structure from ONOK for example?
Code:
struct DlgParam{
std::wstring IEDllPath;
CString folderName;
};

I have made a simple Pane class so that I can encapsulate a winapi Dialog.
I call it as:
Here the code I have, but it displays no dialog.
Here is what I do in main:
Code:
Pane(&hDlg, hInstance, nCmdShow);
while((ret = GetMessage(&msg, 0, 0, 0)) != 0)
{
if(ret == -1)
return -1;
if(!IsDialogMessage(hDlg, &msg))

For getting the share folder name i have been used the following code , here i am able to get the folder names . But the problem what i am facing is along with the share folder created by the user it gives some extra folder also , i don't know how to prevent the programe to hide that unnecessary folder names . Like in my case i am getting "cc_views"(used for clearcase) and "Users" folders , which i want to remove from my folder lists .
I wrote the following code:
#ifndef UNICODE
#define UNICODE
#endif
#include <windows.h>
#include <stdio.h>
#include <lm.h>
#pragma comment(lib, "Netapi32.lib")
#pragma comment(lib, "Advapi32.lib")

I made a dialog to have a customizable msgbox. (custom icon, custom caption on buttons). This is how I try to display an icon on the dialog but it is not working.
HICON hIcon = LoadIcon(NULL, IDI_QUESTION);
HWND hImageCtl = GetDlgItem(hDlg, IDC_STATIC);
::SendMessage(hImageCtl, STM_SETIMAGE, IMAGE_ICON, (LPARAM)hIcon);
//SendDlgItemMessage(hDlg, IDC_STATIC, STM_SETICON, (WPARAM) hIcon, 0);
