dialog

问题 Before I begin, I have googled this to death and there are many posts about how to prevent the save prompt. I am having an issue showing the save prompt. I am building the template editing portion of a document generation system in C#. The system will edit 'dot' and 'dotx' files. Before outlining the problem, the environment I am using for development is running Visual Studio 2010 and Word 2010. It will eventually run on other versions, but i would like to get these versions functional first.

问题 Question: Does anyone know how to change the current directory of an already running open file dialog? Details: I have a customized open file dialog (using a custom template to add extra controls) that also has all the validation, existing checks, and creation tests turned off (via the OpenFileName flags). Turning those things off disables the built-in behavior of the dialog that will cause it to change the currently displayed folder if the user types a folder name into the "file name" combo

问题 I'm developing a WPF application that's meant to live in the tool tray, so it doesn't involve any windows. Right-clicking the tool tray icon brings up a menu with a Configure Report Path... option, and I'd like to display a folder browser dialog to the user when this is clicked: What I'm finding is that when the option is selected, a dialog opens and immediately closes unless I assign some window to Application.Current.MainWindow and show it before opening the dialog. This is the code I'm

问题 I have an asp.net page with a timer embedded in an UpdatePanel (UpdateMode="Conditional", ChildrenAsTriggers="false"). The timer is responsible for updating some components of that page every few seconds. There are also some HyperLink controls on the page and they open a JQueryMobile dialog when clicked (data-rel="dialog"). The problem is that the timer i mentioned causes postback every few seconds. So when a dialog is opened and then closed, the first such postback after then causes the

问题 I have an MFC dialog containing a dozen or so buttons, radio buttons and readonly edit controls. I'd like to know when the user hits Ctrl+V in that dialog, regardless of which control has the focus. If this were C#, I could set the KeyPreview proprety and my form would receive all the keystrokes before the individual controls - but how do I do that in my MFC dialog? 回答1: JTeagle is right. You should override PreTranslateMessage() . // Example BOOL CDlgFoo::PreTranslateMessage( MSG* pMsg ) { /

问题 I have connected a photographic flash unit to my computer using a relay switch connected to the serial port. The following code causes the strobe to flash at 4Hz for 10 flashes: #include <windows.h> //Initialise Windows module int WINAPI WinMain (HINSTANCE hThisInstance, HINSTANCE hPrevInstance, LPSTR lpszArgument, int nFunsterStil) { //Define the serial port precedure HANDLE hSerial; int freq = 4; int iterations = 10; int x; for ( x = 0; x < iterations; x++) { //Fire the flash (open the
