Re: How to make a vertical text into the Edit Control?

9-Aug-07 3:09

Draw vertical text is very very simple:

CFont VertFont;
LOGFONT LogFont;
HorzFont->GetLogFont(&LogFont);           // Get the info from an horizontal font
LogFont.lfEscapement=900;                 // Modify the info (now it is vertical):->
VertFont.CreateFontIndirect(&LogFont);    // Create the font
tmpDC.SelectObject(&VertFont);            // Apply to the DC
tmpDC.TextOut(x, y, "bye bye, Russell");  // Use it :cool:

Your sample for drawing and not for the CEdit-derived classes. Changes CEdit font by SetFont methods hasn't effect.

Another way then is to put a normal CEdit control invisible somewhere, then drow it and on a tmp DC, rotate it 90 degrees and than draw it in the real DC.
But, then, probally you have also to wrap (and rotate) the mouse interaction to send right information to the real CEdit control. Dead | X|

Hi I have developed a program in C++ and I would now like to implement a sort of uninstall function which will delete all the files created so far by the application, including the application itself. How can I do it, since the application can't delete itself if it is still running?

Any advice please!

actually, it can, as the program is loaded in memory when it runs...

Actually, no, as the exe is locked.

What's the syntax of ExitProcess()?
Could you please make an example as if I wanted to delete a program called Program.exe

Many thanks

Do you need an Installer?

Oh come on, no install program is that complicated for you to not cope with Pascal for a few lines...

A simple way is use the key RunOnce on the windows registry to delete all files and directoryes.
Also you can run a bat file that do this, or, of course, you can run an exe file to do this and delete it after that it ends.

Create Registry Key with C++

I am wondering if anybody could help. I have written a program in C++ and now I need to read and create Registry Keys. I know how to do it in VB (it's pretty simple) but I have no idea on how to do it in C++. I didn't find VS and MSDN online help resources very useful.

To read a key I have tried:

#include "stdafx.h"
#include <ctime>
#include <math.h>
#include <fstream>
#include <string>
#include <iostream>
using std::dec;
using std::hex;
using namespace std;
#include <iomanip>
using std::setprecision;
using std::setbase;
#include <cstdlib>
using std::atof;
#include <windows.h>

#pragma comment(lib, "user32.lib ")
#include <stdio.h>

int_tmain(int argc, _TCHAR* argv[])
{
HKEY temporarykey;
TCHAR License[64];
DWORD lpcbData = 64;

LPCWSTR lpPointer;

char Licenza[] = "License";
lpPointer = &Licenza[0];

lpPointer

RegOpenKeyEx(HKEY_LOCAL_MACHINE,

"SOFTWARE\\XXX\\License",0,
KEY_QUERY_VALUE ,&temporarykey);

RegQueryValueEx(temporarykey,

"License", NULL, NULL,
(LPBYTE)License, &lpcbData);

RegCloseKey(temporarykey);

return 0;
}

But I get these two errors:
Error 1 error C2664: 'RegOpenKeyExW' : cannot convert parameter 2 from 'const char [23]' to 'LPCWSTR' c:\documents and settings\edy\my documents\my programs\giovi read reg key\giovi read reg key\giovi read reg key.cpp 31

Error 2 error C2664: 'RegQueryValueExW' : cannot convert parameter 2 from 'const char [8]' to 'LPCWSTR' c:\documents and settings\edy\my documents\my programs\giovi read reg key\giovi read reg key\giovi read reg key.cpp 34

What am I doing wrong? I am working in c++ / Console Win32. Any advice please? Thank you

Use _T("SOFTWARE\\XXX\\License") and _T("License") instead
