You need to convert your int in CString.
For that you have The CString::Format function
CString strNumber;
strNumber.Format("%d", nYourNumber);
SetDlgItemText(ID_TEXT, strNumber);

Use SetDlgItemInt() instead.

I'm in a middle of writing my little own framework. I've created a class; lets call it MyFrameWorkApp, and all applications must have one and only one instance of this class (or more likely a class derived from this class). This class should, like in MFC, be instanciated somewhere at global level. (i.e. Before WinMain is called) Then I want WinMain to somehow get a pointer to this instance. This is how MFC does it...
int AFXAPI AfxWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow)
{
ASSERT(hPrevInstance == NULL);
int nReturnCode = -1;
CWinThread* pThread = AfxGetThread();
CWinApp* pApp = AfxGetApp();
.
.
.Now, in my case both pThread and pApp points to the CWinApp instance, but that's normal I guess. Later in AfxWinMain, pThread->InitInstance() is called. I want the WinMain-function in my framework to do the same: Get a pointer to the MyFrameWorkApp instance, and call a particilar function. I've tried _lots_ of times to singelstep how MFC does this, my I can't figure it out. Can someone help me?

Use a Singleton Class,
That will ensure that u can always
get the singleton object thru a well
known pointer or fn and that it is created
only once.

Well, trying to copy MFC is fraught with danger and intrigue.
MFC tends to do a lot of monkey business behind the scenes. For instance, quite often, instead of calling new, MFC will allocate memory for an object, then call the objects constructor manually. I guess it makes sense if you consider that MFC came from DOS originally, over 10 years ago.
Anyways, how MFC does this is hidden in the constructor for CWinApp. In there, They do a few things, such as a module state variable = this (this being the CWinApp object) and doing some asserts that will assert if you try to create more than one instance.
This isn't the best way to do this, however. The better way would be to make your MyFrameWorkApp a singleton object, which makes it impossible to create more than one instance. If you don't know what a singleton is, I suggest doing some web searches on it, or buying the most excellent book "Design Patterns".
The reason you can't single-step into this is that the CWinApp's constructor get's called *BEFORE* WinMain. You have to put a breakpoint in CWinApp's constructor before you execute the app.

HI!
Is it possible to do this:
// Timer one
SetTimer(1, 1000, NULL);
// Timer two
SetTimer(2, 1000. NULL);
My app is kind of an alarm app. It checks the alarm time if it is equal with the current time.. it works just fine! But when the second timer is running too, witch is set to interval 1000 too, the first timer wont be killed when the time is equal to alarm time!! WHY?? I guess it's because it will not work with two timers with the same interval, but I've tride to set the second to 1001 milisec but it wont work any better!"!  ( (
I may be didn't explained so good but you can at least answer this:
Is it possible to do this:
// Timer one
SetTimer(1, 1000, NULL);
// Timer two
SetTimer(2, 1000. NULL);

Yes, of course. You should post some more code to show how you're setting them up and using them.

Ok, here is the OnTimer function:
All comments are writen in SWEDISH...
The problem was that when I try to launch open the dialog in timer 1 the KillTimer func doesn't seems to be called or something? The dialog boxs appears, and appears, and appears.... but when next minut comes then it can be called and timer 1 is killed... Hope I could explain it! And this happens when I have to timers in use at the same time

You need to put a break between your switch statements - as it stands, case 2 causes both blocks of code to execute.

I have a class derived from CWinThread. I create an instance of the object using new and then call CreateThread. So now I have a thread running. My question is:
What are the consequences, if any, if I call a member function of that object? Say I set the thread running then called the objects getCount() function. I've not had any luck with this. Just wondering if it's impossible or is there some stack issues I'm not aware of.
Seems like a strange question I hope I explained well enough. Lemme know if I didn't.

You're asking if you can call member functions of the object you created using new, right? It should be OK; you'll just be calling the functions from within the original thread instead of the one just created.

"I've not had any luck with this."
What I meant was I did call the function after I set the thread running. I was passing a pointer into the function. But as soon as I step into the function (in the debugger) the pointer is garbage. I thought it could be because the function is in the same object as a thread.

Yeah that's what I thought but I wanted an un biased opinion. Thanks for the reply!

I have a function that is called be visual basic to draw to a picturebox. What that picturebox has is some video on it and I want to be able to change the colours of the image. I am trying to use CreateDIBSection but I seem to be missing something as I can't change the colors. I know that I have the right DC because I can draw a rectangle on it but I can't seem to get a proper bit set. Here is my code:
void __stdcall OverlayMask(long hWnd, long MaskArray)
{
RECT rc;
LONG lWidth = 0;
LONG lHeight = 0;
BITMAPINFO bmi;
HBITMAP hbmp = NULL;
BYTE* bpDIBits = NULL;
GetClientRect((HWND)hWnd, &rc);
lWidth = rc.right - rc.left;
lHeight = rc.bottom - rc.top;
ZeroMemory(&bmi, sizeof(BITMAPINFO));
bmi.bmiHeader.biSize = sizeof(BITMAPINFOHEADER);
bmi.bmiHeader.biWidth = lWidth;
bmi.bmiHeader.biHeight = lHeight;
bmi.bmiHeader.biPlanes = 1;
bmi.bmiHeader.biBitCount = 24;
bmi.bmiHeader.biCompression = BI_RGB;
bmi.bmiHeader.biXPelsPerMeter = 72;
bmi.bmiHeader.biYPelsPerMeter = 72;
HDC tmpDC = GetDC((HWND)hWnd);
hbmp = CreateDIBSection(
tmpDC, (LPBITMAPINFO)&bmi, DIB_RGB_COLORS,
(LPVOID*)&bpDIBits,
NULL, 0);
if (hbmp == NULL) AtlTrace("Unable to create DIB Section\n");
if (bpDIBits == NULL) AtlTrace("Unable to create DIBits\n");
HBRUSH hBrush = CreateSolidBrush(RGB(0xFF, 0x0F, 0xF0));
FillRect( tmpDC, &rc, hBrush ); // <- This works fine.
for (int i = 0; i < (lWidth*lHeight/3); i++) //<- This
{
*(bpDIBits++) = 0;
*(bpDIBits++);
*(bpDIBits++) = 0x66;
} // <- doesn't
AtlTrace("1) OverlayMask: %x %x", hWnd, MaskArray);
GdiFlush();
ReleaseDC((HWND)hWnd, tmpDC);
}
Thanks in advance,
Clint Singer

Well, after creating the DIB section (which I assume you have no problems with) and doing whatever you want with bpDIBits you will have to paint the bitmap by:- creating a DC compatible with tmpDC (use
CreateCompatibleDC for this),
- selecting the bitmap you've created into this compatible DC with
SelectObject(compatibleDC,hbmp),
- doing the actual painting to
tmpDC with BitBlt(tmpDC,0,0,lWidth,lHeight,compatibleDC,0,0,SRCCOPY)
Also, don't forget to clean everything up (compatibleDC,hbmp...)

I´m having trouble using "global" ado recordset pointers in a project.
I have a recordset in a +/- fixed window, that I want to used by other windows that are constantly beeing created and destroyed.
I can access the window pointer easily but when i try to access the recordset pointer the program crashes. The weird thing is that i can visualise the pointer in the debug windows correctly. the code is below, what am I dooing wrong?
class CMainFrame : public CFrameWnd{...
public:
_ConnectionPtr pCon;
CWnd *pTrabalhadoresView;
...}
class CDLG_TRABALHADORES_VIEW : public CResizableFormView{...
public:
_RecordsetPtr
pRstTrabalhadoresDados;
...}
void CDLG_TRABALHADORES_VIEW::OnInitialUpdate()
{...
pMain= (CMainFrame *)AfxGetMainWnd();
pRstTrabalhadoresDados.CreateInstance(__uuidof(Recordset));
pRstTrabalhadoresDados->Open("trabalhadoresdados",_variant_t((IDispatch *)pMain->pCon,true),adOpenDynamic,adLockOptimistic,adCmdTableDirect);
...}
void AnotherWindow::OnSomething(){...
CMainFrame* pMain= (CMainFrame *)AfxGetMainWnd();
CDLG_TRABALHADORES_VIEW* pTrabalhadoresView=(CDLG_TRABALHADORES_VIEW*)pMain->pTrabalhadoresView;
_RecordsetPtr pRstTrabalhadoresData=pTrabalhadoresView->pRstTrabalhadoresDados;
/* UNHANDLED EXCEPTION IN TEST.exe: 0xc0000005: Access violation */
...}

Texas:
You need to put the recordset, in the MainFrame and to Instance it in the MainFram. Also you can make the same in the CWinApp Class...
You will can access to the recordset from every window, using
<br />
CWinApp::_RecordsetPtr<br /> \

Hi,
If I want to find unwanted DLL in the system, how should I find it, is there any method available
Kindly reply me
Regards
John
|
|
|
|

Do you know the name of the DLL? If so, then it's just like finding any regular file on the system. FindFirstFile and FindNextFile are the APIs which immediately come to mind for doing that. The CFileFind class is an alternative if you're using MFC. Other than that, I don't know but I'm trying to remember an API call I came across a while back that would search the hard drive for you. If I remember, I'll post it.

I am trying to replace spaces with newlines \n's in a file to create a single column then I can read the file using ReadString to get one value at a time but it doesn't work. It still thinks the file has the original set-up of rows and columns instead of just a single column. Can anyone explain why?
Here is the code...
CString cFilename = lpszPathName;
CStdioFile fDataFile,fDataCol;
CString szValue;
CString szRow;
fDataFile.Open(lpszPathName, CFile::modeRead);
fDataFile.ReadString(szRow);
int nFirst = szRow.Replace(" ","\n");
while(fDataFile.ReadString(szRow))
{
int nCol = szRow.Replace(" ","\n"); }
fDataFile.Close();
fDataCol.Open(lpszPathName, CFile::modeRead);
BOOL b = fDataCol.ReadString(szValue);
if(TRUE == b)
{
m_nRows = atoi(szValue);
}
b = fDataCol.ReadString(szValue);
if(TRUE == b)
{
m_nColumns = atoi(szValue);
}
m_nValues = (m_nRows*m_nColumns);
m_GraphData.SetSize(m_nRows);
int nRowCount;
int nColumnCount;
for (nRowCount = 0; nRowCount
|
|
|
|
|
Without looking at your code I'm going to guess that it's because you need to use \r\n instead of just \n. Try that and see if it makes a difference.

Alvaro

does anyone know how i can use powerpoint presentation files in my MFC app and make a slide show in full screen with one? (like the slideshow in powerpoint itself). Is there an active-x container for this or something, or is the powerpoint format simple enough to create the slideshow from scratch?
Easiest way?
Thanx

Hello everyone.
My question and current task is kinda simple. All I need to do is to send an email to the network admin from my MFC application that runs 24/7 on the server box. Sometimes, for unknown reason, the server box freezes and the only possible action(if I solve this problem) is to send an "alert" message to the network admins that "box needs to be rebooted ASAP".
I know that there are lots of COM components(like ASP mail) out there that facilitate email protocols. As well, there is a number of socket API's and classes.
Does anyone know which way is the fastest and easiest for MFC app to send a simple email.
Big thanks in advance.

Use ShellExecute with the program set to a mailto link protocol; i.e mailto:admin@company&subject="blah" etc... using &body. Not a very full answer but I've got some VC problems at the moment so can't access documentation.
