• Internet Explorer Development IE7 Forms Auto Complete Stopped Working

  I’ve deleted by mistake the registry key: Software/Microsoft/Internet Explorer/IntelliForms/Storage1 As a result, IE7 Auto-Complete stopped working. I tried to fix the problem by recreate the deleted keys under IntelliForms: Create new Key: Storage1 Create new empty Value: C6FB044EC2BD401521D6B1082276415638196D8004 It didn’t work for me. How can cause IE7 to renew the Auto-Complete mechanism That was my ultimate solution, too. Now, all is OK. Interestingly, I also noticed that Outlook wouldn't work properly when I was having this problem with IE autocomplete. Outlook was apparently unable to manage the password for the IMAP connection to my mail ser ...Show All

• Software Development for Windows Vista PerformTimerCallback called on cancelled task - bug?

  I have a ListenNamedEventActivity that executes its childs in Execute(): foreach ( Activity branch in this .EnabledActivities) { branch.RegisterForStatusChange( Activity .ClosedEvent, this ); executionContext.ExecuteActivity(branch); } (each branch is a sequence activity) It cancels all other childs as soon as one completes: foreach ( Activity branch in this .EnabledActivities) { if (branch.ExecutionStatus== ActivityExecutionStatus .Initialized || branch.ExecutionStatus== ActivityExecutionStatus .Executing) executionContext.CancelActivity(branch); } executionContext.CloseActivity(); However one activity is a DelayActivity and I get the following exception after the workflow completes: Unhandled ...Show All

• Visual Studio Team System Data Compare - Next Button Grayed Out

  Trying to a Data Compare. After I select my 2 data sources, I go to the next screen where I select the tables/views. I can select all tables or select individual tables, but no matter what I do the Next button is grayed out. Clicking the Finish button just closes the wizard without doing anything. What am I doing wrong I am running the initial CTP that was distributed at Tech Ed. Do you the tables you are comparing have a primary key constraint or an unique index present If not we can not compare the data, because there is no order in which we can compare the rows between the two tables or views. -GertD "DataDude" Development Manager ...Show All

• Windows Forms Any FormBorderStyle type without titlebar

  Hey, I have no idea how I managed to get this result (it was a while since I wrote the code) but somehow I got my AboutForm, simple as can be with text and stuff, without a title bar in ANY FormBorderStyle enumeration. If I choose FixedSingle or FixedToolWindow I get a neat thin black border for example. Don't get me wrong, this is great I love it - but I can't replicate it! Nothing seems different in the public properties nor in the generated code. What have I done :) Cheers That's a pretty neat trick, you'll have to tell us how you did it when you find out. Use Spy++ to look at the style flags for the window. The WS_CAPTION style flag enables the title bar. You'd have to write code like this to turn it off: protected override Cr ...Show All

• Windows Forms scrolling big image - poor performance

  hello, I'm writing small graphics tool in which I need to scroll big image (approx. 5MB JPEG). I wrote control that derives from UserControl, gave it AutoScroll property and this is the point I'm stuck. after performing a scroll I must wait half a second for the control to refresh totally - what causes so bad performance image size is about 5000x5000 pixels. when I scroll the same image in Photoshop or Microsoft Paint, this problem doesn't occur. how to solve this problem no, I haven;t tried this. it's sure that memory usage is key issue here, but - as I mentioned - there are many apps that don't show this leak of performance. I have written a small app in Flash and it scrol ...Show All

• .NET Development Exceptions and Invoke

  Hello, I have found some problems while handling exceptions raised by methods, when the methods where invoked using the ‘Invoke’ method of the Control object. My application is a UI application but some of the UI methods are called from other threads than the thread that handles the UI (cross-thread invoke). For that reason I am using ‘InvokeRequired’ and most of the times Invoke (Synchronous invoke) to call the UI methods. The problem arises when the UI method called this way wants to handle exceptions. If I run the application inside Visual Studio (debug mode) exceptions are caught correctly as expected. If I run the application standalone, exceptions are not caught and the application sho ...Show All

  Does the System Namespace has something like system.path I need print out the current cs files path.. because for some reason I'm trying to load some images in a program that I'm creating.. but for some reason..

• Smart Device Development Legacy Win32 C/C++ Code to be used in CF

  Hi, My problem is described pretty much in the title. I am using VS 2005. I have some code to use in a Pocket PC 2003 application and it is written in C/C++. What is the suggested way to do this I tried to use the DLL in a PPC project but since it is desktop DLL, i failed to do that. I tried to compile the code in a Smart Device project, i failed to do that too (couldn't find files like wincon.h, io.h, etc)...This code was written to be used in desktop applications. I think this must be a frequent problem that Smart Device developers encounter but I really couldn't find a way to solve this either through forum-search or google. Thanks for any help... Hi , "...

• Visual Basic Change system time using vb.net

  Does anyone know how to change the system clock using code. I want to be able to set the date and time in my code. Any thoughts Thanks!!! well yes the above does it pretty much except you need to place the code in the right place. So declare a datetime object globally as shown. Then in your plus button, add 1 hour (for example) to the datetime object stored globally: Me.theDateTime = Me.theDateTime.AddHours(1) for minus button, do the same thing but do -1 instead to take away 1 hour. Same goes for minutes, seconds, milliseconds, days, months and years. ...Show All
