Calling UpdateData(FALSE) will screw my RadioButton-group selection
-
Here's my problem: I have 2 radio buttons in my dialog-based MFCAppWizard-made application (first radio button has "Group" property and is mapped to m_Operation). Their names are: "Encode" and "Decode" By default (in OnInitDialog) I select the first radio button (otherwise none would be selected at startup) with: m_Operation = 0; I have 2 Static Text controls (IDC_SOURCE and IDC_DESTINATION) both mapped thru ClassWizard to m_Source (CString type) and m_Destination (CString also) At a certain point the user selects a file and the app will write something to m_Source: m_Source = "C:\\MyFile.txt"; But that won't make it visible in the main form so I: UpdateData(FALSE); And it becomes visible. But MY PROBLEM IS THAT IN THAT MOMENT THE RADIO BUTTON SELECTION SCREWS UP. How is that? If "Decode" was selected before UpdateData(2nd radio button - "1") then "Encode" will become selected (1st radio button - "0"). HOW CAN I AVOID THIS? Not calling UpdateData or UpdateData() or UpdateData(TRUE) will cause this: m_Source = "C:\\AnyFile.txt"; does not update visually the static text control in my app. Please help?! ;-) Andrei Rinea

Associate a CStatic object with static text control and call staticobj.SetWindowText("text") to change the text of static control instead of calling UpdateData :) Muhammad Shoaib Khan http://geocities.com/lansolution

UpdateData()should be used as little, if at all, as necessary. Use member control variables instead.

Add a handler for BN_CLICKED for each of your radio buttons. In the handler, set the m_Operation member to the button that was just clicked. It isn't otherwise being updated, which is why it reverts to the old setting when UpdateData(FALSE) is called. void CDlgtestDlg::OnRadio1() { m_Radio = 0; } void CDlgtestDlg::OnRadio2() { m_Radio = 1; } or you can add a single handler for this using ON_CONTROL_RANGE(BN_CLICKED ...)

Allrighte... But if I don't use that darn UpdateData, I CANNOT UPDATE the static text. Let me put the problem in a simpler manner: You have a static text (in Delphi it was called "Label") How do you modify its content and then update it visually so the darn thing on the screen reflects what you wrote in it?! I mean I mapped thru ClassWizard a CString to that static text control named m_Source. If I just say m_Source = "My text!!"; nothing on the screen changes. Especially that darn static text. How exactly do you recommend me to do it? TIA! ;-)

Map a CStatic to that static text control m_source( Just select Control in the combobox where u map a variable, it will autmatically show CStatic in the datatype field) Now if u just want to change the text of static control, and want other controls like radio to remain unchanged, just call this function
m_source.SetWindowText("My Text!!");It will modify its contents and update it visually.. Now to retrieve the text from static control callCString str; m_source.GetWindowText(str);OR U can also useSendMessage(m_source.GetSafeHwnd(),WM_SETTEXT,(WPARAM)0,(LPARAM)"My Text");to achieve the same task *visually updating static text without chaning any other control. This will definately solve your problem.. :) Muhammad Shoaib Khan http://geocities.com/lansolution
