Strange! CP search engine returned the following article as the first result while I searched for "MFC access":
Easy way to mix the MFC Document/View and MS Access database applications.[^]
I sure did get more relevant results when I modified the search terms. Take a look at the CDatabase[^] class as well for your need.

Hi all
How can i convert CString to long.I am try this
CString Content="000995688787";
int newintval=atoi(Content);
result is
newintval=225212472
and
__int64 n64Tmp=_atoi64(Content);
result is
n64Tmp=225212472

You must have used atol (or rather _ttol) instead of atoi. See CString::Format() member if you're already using CString.

Hello, I am prashant workign with one company and doing the Graph Designing into my application. now the issue is that i create the function for populating the graph data but it takes to much time to populate data.
Can any body tell me how to reduce the time for populating data.
the following is my function from which i draw the graph data from one table.
void D_ScripGraphWnd::OnDraw(CDC *pDC)

Please format your code properly because as it is now, it is very difficult to read.
Now to your question: if it is that slow, it's maybe because you are redrawing EVERYTHING each time a repaint is requested. Are you displaying a kind of dynamic chart ?
If you need a standard charting control, you can also look at my sig. I've developped one which is I think pretty ok regarding to performances.

Hi All,
I want to create an Add-In for MS-Outlook in MFC. Please guide me how to do that?

Hi,
im overriding Create function of Modeless Dialog...to increase the font and Dialog size along with the controls inside it... as follows...
BOOL CTestDlgDlg::Create(UINT nID, CWnd* pParent)
{
CDialogTemplate dlt;
// int nResult;
// load dialog template
if (!dlt.Load(MAKEINTRESOURCE(CTestDlgDlg::IDD))) return FALSE;
// get pointer to the modified dialog template
LPSTR pdata = (LPSTR)GlobalLock(dlt.m_hTemplate);
LPDLGTEMPLATE pDlgTemplate = (LPDLGTEMPLATE)pdata;
//pDlgTemplate->style |= DS_SETFONT;
// set your own font, for example "Arial", 10 pts.
dlt.SetFont(L"Century Schoolbook", 18);
// let MFC know that you are using your own template
m_lpszTemplateName = NULL;
//InitModalIndirect(pdata);
// display dialog box
//nResult = CDialog::DoModal();
// unlock memory object
// CDialog::Create(nID,pParent);
BOOL bret CDialog::CreateDlgIndirect(pDlgTemplate, pParent, AfxGetInstanceHandle());
GlobalUnlock(dlt.m_hTemplate);
return bret;
}
The size of the DialogBox along with the controls inside it are getting increased except
the Title bar of the DialogBox.Even the Text is also not getting increased.Pls let me know how can i increase the size of the Title bar along with the font size..without using custom titlebar...
|
|
|
|
|
The font of the title bar of a Window is a system-wide setting and cannot be altered for one particular window. You can see the current font setting for title bars in the Advanced Appearance option of the display settings in the control panel. In fact there are separate settings for the active title bar and the inactive title bar.
If you want a particular window to have a different look for its title bar, you will need to create a dialog box without a title bar, draw the title bar yourself and then return HTCAPTION from the WM_NCHITTEST message handler when the user clicks on the drawn title bar.

I'm recording audio and I don't want to record silence. How can I do that? I'm recording using wimmm.
Is there a command or something like that?
Thank you
|
|
|
|
|
I dont know wimmm, but essentially silence are sample-values in a wave-file that aprox. 0 (there could be some noise). With that knowlegde you could create a program that modifies the wavefile... The Wavefile format is VERY easy, it's just a header followed by samplespoints...

hi all,
i have a service application, which maintains a record of each and every USB being used in the windows system.
in brief, my problem is with the hashmap values getting corrupted in between two threads. one thread picks the database path where values are to be written and other thread writes into that database path.
Service crashes at the, when the below codes are executed.
WaitForSingleObject(*hThreadIterBegin->second,INFINITE);
rename(hThreadIterBegin->first->c_str(),newFileName.c_str());
ReleaseMutex(*hThreadIterBegin->second);
The first thread fetches the values and the values are sent to the second thread so that it can write the necessary things to the fetched value which is the path of the database. but the hashmap value crashes at some point due to which the service crahses at above code executions.
i am not able to identify the exact reason, as to why the value of ThreadMutexMapPrimary changes or crashes when it is called from the second thread???
i am attaching the code below, with declarations and values i received while debugging.
Thankyou.

Your problem seems to possibly be related to an issue we saw in our own software. Switching to an alternate STL provider fixed our issues. See
http://support.microsoft.com/kb/813810[^]
You may well be being affected by this. BTW we switched to STLport a free STL implementation.
If you vote me down, my score will only get lower

In the IDL file it should be [in, out] SAFEARRAY(VARIANT)* oAxisComponentsArray
In the .h and .cpp files it should be SAFEARRAY** oAxisComponentsArray

Hi,
I am facing a problem with IWshRuntimeLibrary::IFileSystem. It is working fine on Win2003,Vista 32 bit. But fails in Win2008 std sp2.
I am using following function from IWshRuntimeLibrary::IFileSystem
1.CopyFile
2.GetFolder
3.FileExists
4.DeleteFolder
5.CreateFolder
I am currently using VC++.
Why IWshRuntimeLibray::IFileSystem is failing. Can I have any alternate solution.
|
|
|
|
|
Please debug and check the reason for failure
but i have the alternate solution as to suggest you to use SDK APIs
CopyFile :: Copies an existing file to a new file.
CopyFileEx :: Copies an existing file to a new file.
CreateDirectory :: Creates a new directory.
CreateDirectoryEx :: Creates a new directory with the attributes of a specified template directory.
CreateFile :: Creates or opens a file object.
DeleteFile :: Deletes an existing file.

Hi all,
I m creating a Property Sheet with help of CPropertySheet class,in Property Pages i m using Groupbox i want make bold the text of groupbox please help me how can i do this.
thanks in advance.
To accomplish great things, we must not only act, but also dream;
not only plan, but also believe.

|

This may not be an answer to your question, but the easiest way to do this is to place a picture control with a bitmap of the text with the required font size over the group box.

You mean some text inside the groupbox or the caption of the groupbox? If the caption of the group box, you could rename the ID of the group box such that it is NOT IDC_STATIC and then add a control variable to it (say m_GroupBox) and then call m_GroupBox.SetFont();
It is a crappy thing, but it's life -^ Carlo Pallini
