• JasonY validating a tab page

  I have a tab page validating event to prevent the user from switching to other tab page if the current tab page has some required information not filled. When the validating fails, e.cancel is set to true. Now the problem starts. Any button or check box doesn't work anymore on that tab page. I mean button click event won't fire. The check box can't be checked and unchecked. The only thing that can be done is to enter information in the text field. Is this behavior by design If not, what can I do to make the button and check box work when the tab page validating fails Thanks for any suggestions. Ok, did a bit of digging, and this worked for me: private void tabPage1_Validating(object sender, CancelE ...Show All

• WalidM DialogResult not detecting DialogResult::OK

  I'm using the following code to try and open a file using the openFile dialog box, however it always enters the 'Open file cancelled' section, even when the Open button is pressed. ::DialogResult ^openfileresult; openfileresult = openFileDialog->ShowDialog(); if (openfileresult == ::DialogResult::OK) { // Open the file here (never gets to here) } else { // Open file cancelled (always ends up here) } If however I cut out the intermediate variable and do a direct comparison by changing the code to the following, it works perfectly as it should. if (openFileDialog->ShowDialog() == ::DialogResult::OK) { // Open the file here } else { ...Show All

  Hello, I have created a datagridview with the 5 following columns. 1)CourseName (Combobox) 2)CourseType(Combobox) 3)DateFrom (DateTimePicker) 4)DateTo (DateTimePicker) 5)CourseDetails (Textbox) What i want to do is to fill this datagridview with data from an Access database (Table Courses).

• ps0118mj Very slow load of C++/CLI project with WinForm

  I have a large C++/CLI project that I'm building with VS 2005. I've added a WinForm to the project that contains some 3rd party components (DevExpress). It compiles and runs, but when I load the project into Visual Studio it takes 5 minutes to start up! Before I added the WinForm it took about 10 seconds. I took a look at what VS 2005 is doing during this time and it's creating 94 folders in C:\Documents and Settings\Fred\Local Settings\Application Data\Microsoft\VisualStudio\8.0\ProjectAssemblies and copying my project's .EXE and .PDB file into each one. Unfortunately, the .EXE is 11MB and the .PDB is 32MB... all-in-all it's copying 3.82Gb of data (4K at a time) which takes a while. Also, if I make any change in the form designer an ...Show All

• pinoyz ListBox question

  Hi to all! I have a question about ListBox control. I would like to add some items on a ListBox which are objets (for example type of MyOwnObject) and are not strings! When I add my objects to the ListBox (myListBox.Items.Add(myOwnObject)) of corse nothing displays on the ListBox. I would actually like to display only some properties of my objects (for example myOwnObject.Name + myOwnObject.Version + myOwnObject.LastUpdated). I don't know how to do it. The fact is I want to have the whole objects in myListBox.Items because of the binding (raising events) not only strings. Thanx for any advice, Ziga Hi fddsfsdf, A common question, the ListBox ObjectCollection is confusing. When&nbs ...Show All
