Writing Variables in CDialog with MFC
-
What I meant was, you could use
sprintf()(which works exactly likeprintf()but writes to a string vs. standard output) to display values of variables which could be shown by a static text control (i.e.CStatic) or an edit control (CEdit). The latter is preferred, since it supports scrolling, which can come in handy when displaying large amounts of text. The actual display would typically occur within a button handler. For example:CMyDialog::OnBtnFooClicked()
{
// Better to use a symbolic const instead of "256"
char szResult [256];// Compute and display nFoo int nFoo = someFunction(...); sprintf (szResult, "nFoo = %d", nFoo); m\_myEditCtrl.SetWindowText (szResult); // Even better to use CString and Format() CString strResult; strResult.Format ("nFoo = %d", nFoo); m\_myEditCtrl.SetWindowText (strResult);Hope this helps. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com
I understand now... Everything works out perfect besides for: "m_myEditCtrl" I appoligize for my illiterate-ness in MFC... C:\*\ClientDlg.cpp(190) : error C2065: 'm_myEditCtrl' : undeclared identifier C:\*\ClientDlg.cpp(190) : error C2228: left of '.SetWindowTextA' must have class/struct/union type Other then that i understand what you mean and how it will work, but what am i doing wrong when it comes to "m_myEditCtrl"? What do i replace it with? Just a Human Trying to Live in a Computers World.

Thanks to "toxcct" and "cedric moonen" Ive learned how to Link my CDialog's together, Thank you both!
#include Button01Dlg.h void CClientDlg::OnButton01() { CButton01Dlg dlg; dlg.DoModal(); }But Ive come to Notice that only Text can be added to the CButton01Dlg on interface... I was wondering if there was a way to somehow get printf or cout working in Button01Dlg.cpp in order to apply variables?... Thanks for any Help you guys seem to be the best forum ive found yet!

No, those are for console-based applications.

m_myEditCtrlis aCEditmember of your dialog class, declared in the dialog's.hfile. You will also need to associate the member with an edit control in your dialog template. You can do this dragging an edit control into your dialog template (using the resource editor) and using the ClassWizard to associate theCEditmember variable with the control. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com -

NewbieStats wrote: Im still alittle Queued... You need to first add an edit control (eg:
IDC_MY_EDIT) to your dialog template using the resource editor. Next, use the ClassWizard to add them_myEditCtrlvariable (category = Control). Since you're new to VC++, you may want to refer to an introductory text to help you get going. Meanwhile, see this[^] link to see how to add controls to a dialog template. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com -

It looks like the forum ate one of my replies. In answer to your question about the Control toolbar, here's how to display it: In VS2003, do View|Toolbox. In VC6, double-click the dialog in Resources tab, then right-click the workspace and select "Controls" from the popup menu. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com

It was the closest thing to
printf()which he's familiar with. In my later post I recommended that he useCString::Format(). /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com
