Syntax error

[toxcct]

read my other answer... you included the headers in the wrong file

[toxcct]

you're wrong eli. the class wizard removes the leading C to the file names containing the definition and the implementation of the class beeing created, not directly on the class name. moreover, look at the errors returned by the compiler : d:\parichay\desktopsearch\desktopsearch\updatedlg.h(54) : error C2501: 'CCreateDlg' : missing storage-class or type specifiers yes, the class is effectively CCreateDlg

Hi v2.0. You are right:doh: I didn't see that he included the CCreateDlg header file in the Updatedlg implementation file and NOT in the UpdateDlg header file. About the class wizard - for some reason , in my projects , the class wizard removes the leading C from the class name as well. With best regards, Eli

Do you realy have a sub directory called desktopsearch inside the directory with the same name?

I think the error is because you are cross-including files; I mean including fileA.h in fileB.h and fileB.h in fileA.h etc. You could just declare the class like: class CCreateDlg; Then declare a pointer: CCreateDlg* m_pDlg; etc. this is this.

Thank u very much its working.

Hi, i have new button on sigle click i want a dialog window to open i have declared variables as follows.. can anyone help to solve this problem..??

I don't think you are very familiar with pointers and their uses. Using the pointer to declare the variable would mean that you have to give it memory by using the new operator. Then create the dialog using Create(...) then show the dialog using ShowWindow(...). This could be the code: class CCreateDlg; //Then declare a pointer: CCreateDlg *m_dCreateDlg; Now on button-click: m_dCreateDlg = new CCreateDlg(); m_dCreateDlg->Create(IDD_WHATEVER);//use the ID your dialog template uses here. m_dCreateDlg->ShowWindow(SW_SHOW); This would create a modeless dialog. Note that this would give memory leaks if you do not dispose if off correctly. And if you want to re-use the pointer to create the dialog again, there could be problems. Another way would be: m_dCreateDlg = new CCreateDlg; m_dCreateDlg->DoModal(); this is this.
