char number[100]

to turn it in to a int if the user enters a charcter they going to get sumthing crazy but other then that you could use if or catch statements

What ?? Are you kidding ? You mean you want to use a static_cast on the char array to convert it to an integer ? Oh man, that is just plain wrong.

A Problem with Doc-View SDI App

Hi,

I am just once again posting the question which I have posted a couple of days back. Of course, it hasn't attracted any member attention, but I am just posting again now with a hope that some members may respond. I assure you all that I don't bother and abuse this forum again by repeating the same question. Kindly understand.

Shanmukha

Hi,

I have a problem with one of my Doc-View Application. In fact, I am novice in doc-view apps. I have a CFormView based SDI app coded in Visual C++ 6.0 environment. The user interface has three modeless dialogs embedded in a CTabCtrl, One ChartCtrl and CListCtrl. I observed a funny behaviour while opening a stored document (not Word document) by double clicking on it. The view is not getting updated correctly. But if I open the the file by File-> Open command, every thing working fine.
Let me explain a bit about how I coded the app for better comprehension.
1. The document has a user defined class which handles the serialization on its own (based on Ravi Bhavnani code).

2. The List control paints its contents using NMCustomDraw feature.

3. By digging into the code I could find that OnNewDocument() function is not getting called while opening tha App from Shell (i.e. by double clicking on the file), instead the OnOpenDocument() is called. And all other Doc->DeleteContents() and Serailization, View->IntialUpdate() and View->OnUpdate() working OK but the List Control not getting updated.

4. But if you open the file by File ->Open command, since the SDI app gets started with a new document every thing looks OK.

5. Same is the case by opening with command line Start-> Run-> MyApp xyz.tnf .

6. I found even the OnCustomDraw() function getting called.

7. I then tried to get into the undocumented DocManager classes etc. but I couldn't get much help. Even opening file from the Shell, I find App gets one empty document. This I got confirmed with DocManager class other functions.

Finally what I could find is that, the View and Document connection in the low level framework is at fault.

I would be grateful for any help in this regard.

I remain,
Shanmukha

If you have a look through last week's postings on this forum, you will find a few questions about transparent tree controls, backgrounds and labels.

You can ignore the questions by George_George, so that will save you 50% of the effort.

(Just because he didn't ask it...)

Ctrl.

Ok, more seriously... If you look up the controls in MSDN, you'll find that CToolbarCtrl is a thin wrapper around the common controls TOOLBAR window class. CToolbar is a warpper around CToolbarCtrl that makes it play nicely with MFC features like automatic state updating, docking windows, etc.

Use the mid function of CString.

is this useful,

CString sTemp = _T("Tag-10,OnOff-19,Switch-5,Lbl-10,Signal-22,trip-1");
	int pos = sTemp.Find(_T("Lbl")) + 3;
	CString resToken;
	resToken = sTemp.Tokenize(_T("- ,"),pos);
	if (resToken != "")
	{
		int num = _ttoi(resToken);
	};

strok(sTemp.GetBuffer(), "Lbl-");

Use CString::Mid(), as NishantB++ already said to you.

CString str = _T("Tag-10,OnOff-19,Switch-5,Lbl-10,Signal-22,trip-1");
AfxMessageBox(str.Mid(str.Find(_T("Lbl-"))+4,2));//4 and 2 may vary! Depends on your string.

I agree with 4 as he knows and is going to search using that string but if he knows 2 that means he already has the string with him and question is to find that string.
