It is really quite simple.
Use the Find() fn in CString to look for the spaces and extract the data between spaces for col 1 thru 4 using the CString::Mid(..) fn Then use the Find() to look for the decimal point after the 4th space and count over 4 positions from there to determine the end of the 5th column and the start of the 6th column. Keep extracting data as needed. Repeat until the file is complete.

could you provide a code snippet to get me started?

CString sAllData(".01 6438. 41.74 8753. 1.3596159.07 ");

int iPos1= 0;
int iPos2= 0;
for(int i=0; i<10; i++)
{
iPos2 = sAllData.Find(" ",iPos1);
if(iPos2<0)break;
sCol_1[i] = sAllData.Mid(iPos1, iPos2 - 0); //.01

I am doing to embedded programming with a footswitch, I want a CButton to be 'pressed' when the footswitch is pressed and released when the footswitch is released?
Does anyone know how I can programatically give the CButton the 'Pressed' look?
Cheers

I suggest creating an owner drawn button that draws itself as pressed when it's truly pressed as well as when it's pressed property is true. Them it's a simple matter of doing:
m_button.setPressed (true);
m_button.Invalidate();
m_button.UpdateWindow();

When you want to have the program press the button use:
::SendMessage(hwBtn,BM_CLICK,0,0);

so that a Windows Media Player control 9.0 can be run at full screen mode.
If the control be run at full screen mode directly without sucking in keyboard presses, the system would hang after any non-system key pressed.
I am using VC++ 6.0. However, I still have some problems make the control run well at full screen mode.
Anybody can help? If you have some related articles or sample source codes?
Appreciate your help!

You do this by hiding your window, capturing the picture, and then showing your window again.

there isn't another solution? there is not good if i must hide the app in foreground to capture the bitmap and show the app again.

hi.
i´m using an ADO-Recorset (_RecordsetPtr) and i need to know the number of records mached in the last SELECT. So i´m trying to do it by RecordCount, but it doesn´t work
el hombre es libre cada vez que elige y eso es lo que lo hace libre
|

It depends on your Connection::CursorLocation value. If you specify adUseServer you cannot access the RecordCount property.
pConnetion->CursorLocation = adUseClient will make the RecordCount property returning a value.
|
|
|
|
|
Thanks you very much. now recordCount is working very good.
but, do you know if adUseClient is slower than adUseServer ?

here's what MSDN says:
RecordCount Property
The cursor type of the Recordset object affects whether the number of records can be determined. The RecordCount property will return -1 for a forward-only cursor; the actual count for a static or keyset cursor; and either -1 or the actual count for a dynamic cursor, depending on the data source.
|
|
|
|
|
If you're going through all the records anyway then asUseClient won't be any slower.

Mhh... Yes perhaps, but explain your problem, it would be easier for us  !

The target DLL specified in m_strName must be an absolute path (ex. : c:\bla.dll) or in one of the directories listed in your PATH environment variable.

You get this message at startup. But why did you post that piece of code? It tells nothing about your problem.
Could you be more specific, and also put the entire error string from Windows?
|
|
|
|
|
Ok, next question: what is name.dll and where is it?
|
|
|
|
|
Ok, let's see.....
The DLL is loaded run-time with your call to LoadLibrary. If you put the DLL away (removing it from System32 for instance), the program stops complaining it cannot find the DLL. Am I right??
If I am right, then when LoadLibrary fails, you return FALSE. But to who do you return FALSE?.

so, what exactly is your problem then? What are you trying to achieve?

I want to Create a Frame/view/doc structure On a ActiveX Control,but It will be Found Memory leak! And I Found that the reasons is :
CDocManager* CDocManager::pStaticDocManager;
CPtrList* CDocManager::pStaticList;
How Can I avoid Memroy leak?
the Following is My Code :
BOOL Create()
{
if( m_pFrameWnd )
{
if( IsWindow(m_pFrameWnd->m_hWnd) ) return TRUE;
}
CSingleDocTemplate * pDocTemplate;
pDocTemplate = new CSingleDocTemplate(IDR_MAPTYPE,
RUNTIME_CLASS(CMapDoc),
RUNTIME_CLASS(CMapFrame),
RUNTIME_CLASS(CMapView));
// pDocTemplate in destructor function delete this!
CMapDoc * pDoc = new CMapDoc;// in destructor function delete this!
CCreateContext Context;
Context.m_pCurrentDoc = pDoc;
Context.m_pNewDocTemplate = pDocTemplate;
Context.m_pNewViewClass = RUNTIME_CLASS(CMapView);
Context.m_pLastView = NULL;
Context.m_pCurrentFrame = NULL;
CMapFrame * pFrameWnd = new CMapFrame;// in destructor function delete this!
m_pDoc = pDoc;
m_pFrameWnd = pFrameWnd;
m_pDocTemplate = pDocTemplate;
CRect rcMap;
GetClientRect(&rcMap);
BOOL ret = m_pFrameWnd->Create(AfxRegisterWndClass(CS_DBLCLKS), NULL, WS_CHILD|WS_VISIBLE, rcMap,this,NULL,&Context);
m_pFrameWnd->ShowWindow(SW_SHOW);
return ret;
}

I'm not sure if this qualifies as a beginner's debugging question, but...
One of our apps (written in VC6) crashes on a few of a client's machines, and we can't reproduce the crash in our dev environment. He's getting a message such as the one in the subject line. The first address ("the instruction at [xxx]") always comes back the same on all his machines.
What are the basic steps I need to take in order to map this address back to a line of source code?
