• James Johnston Dropdownitems of a disabled ToolstripMenuItem can still be selected

  see https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx FeedbackID=235911 also this post is probably related: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=312139&SiteID=1 I currently use the EnabledChanged event to disable all the DropDownItems (recursive), but this doesn't prevent the items from 'popping up'. Your comment got me thinking & nosing around with Reflector again. I don't think it was intended for the timer to check if the item is disbled. It looks like the class was desinged to only enable the timer in the OnMouseEnter when it is not enabled, and to disable the timer (cancel) in the OnMouseLeave event. For some reason (which I cannot find), the timer does get enabled for disable ...Show All

• neuhawk One more TIFF question

  As long as i am being bothersome to everybody with TIFF questions, I was wondering if anyone has ever seen any code or docs which show the way as regards using extended tiff editing features. (If you haven't tried it, save a bitmap as a .tif file and open it with Windows Fax and Image Viewer (not sure that's the correct name of the default picture view with Windows XP, anyway, the shell program (originally by Kodak, i think) which a fresh out of the box system opens images with). Note the really cool set of extra 'features' that show up on the tool bar -- different kinds of "annotations" and diagramatic elements tthat can be placed on the image which do not become an intrinsic part of the image when it is saved (they must be data ...Show All

• lwsimpson DataGridView - BindingSource - Cell/Row Style

  I am using Visual Studio .NET 2005 I have a DataGridView control in which columns are created manually for greater flexibility. Essentially the DataGridView.DataSource property is set to the BindingSource object. From there, the BindingSource object is bound to an ArrayList - which allows me to update the ArrayList with objects; and simply calling BindingSource.ResetBindings() allows the DataGridView to be updated as well. However I have recently found about the DataGridViewRow.DataBoundItem() method which allows me to identify/retrieve the underlying object corresponding to the data-row. Therefore change to my previous design model is likely inevitable. But the problem I still can't seem to solve is modifying the style of the row ...Show All

• JohnRobbins Thanks, but I think I tried it before!

  Dear all, Me and my friend are new to visual studio 2005 express edition. We are trying to build a simple desktop database application. Now both of us have different connectionString to the database in our computers (which is quite obvious).At first, we used hardcoded connection strings in our apps. So it was a huge task to replace all those lines as we shifted our computers to share our works. For compatibality, we were trying to use the app.config file for the connectionString, which looks like : (in my computer) < xml version = " 1.0 " encoding = " utf-8 " > < configuration > < configSections > </ configSections > < connectionStrings > < add name = & ...Show All

• Ceej100 problem with signing application and deployment manifest

  Hi... Using mage.exe tool, when I want to save my application manifest and sign it with my certificate, I get: Unable to save {filepath}: An internal certificate chaining error has occured. What could that be On the other hand, if I choose " Don't sign ", then I get an error (I think this is a bug), when setting the Application reference in deployment manifest: The Application Manifest is not signed - {filepath} So it would be nice to achieve both: possibility of signing the deployment with my certificate, as well as having an option of not signing it. Now I don't have either !  Is there something wrong with my certificate It's been issued by my country - Slovenia. Glad to help! ...Show All

• Abhishekbhadouria String Function for repeating character string

  in VB6 we can use String Function for repeating character string of the length specified, what can be used in windows mobile or visual studio Many thanks, that really helps, learning yourself from a book can be tricky sometimes Try this: Dim a As New String("x"c, 3) Ok, thanks Hans, that worked as an interim measure So how would the following embedded code be converted then buffer = Trim(UCase(Form3.Text1.Text)) + String(5 - Len(Trim(Form3.Text1.Text)), " ") As a work around I used....

• woodsy99 Drawing Lines or Circles on a picture box

  I am having difficulty getting a line to be drawn on a picture box.  The situation is that I have developed a program that calculates the orbits of the planets around the solar system.  Each planet is represented by a picture box.  After each iteration of the solar system, I move the PictureBoxes to the new screen location and then I want to draw a filled in circle in the picture box (so that it looks like a planet).  The problem is that no graphics are being displayed, but at the same time I get no compile or run time errors.  The picture boxes are being moved but no graphics are being displayed. The code that I am using to move the picture boxes and draw the graphics is shown below.  ...Show All

• Bruce Bukovics Closing forms in Control validation events...

  I am developing an application with custom security mechanism. Whenever a TextBox on one of my application's form loses focus, I need to validate it. Depending on its contents, I sometimes have to close the form. The validation occurs in the security mechanism implemented, which closes the form using the My.Application.OpenForms collection, if need be. It took me a complete day to figure out that a form cannot be closed if one of its controls Validating or Validated events are being processed (the Form.Close() instruction simply doesn't do anything as if it were not there). Can someone tell me why it is so, & how can I overcome it We have a similar issue where we may be deep in the callstack and we ...Show All

• paul1857 Performance Counter Instances (InstanceName) how to deploy?

  I have a neat application (service) that sports a couple of PerformanceCounters. Because these counters will be used by several other services I added an InstanceName to each of them. All works fine. Now to the setup and deployment. After much tweaking, checking and browsing I've found out how to deploy the performance counters with the ProjectInstaller. Unfortunately the installer for performance counters let me setup the counters but not the instance names. How do I tell my deployment project to create multiple instances (to be addressed with the InstanceName property) during setup VS2003 here.   Btw. the instance names appear as lower case. For instance, "Gateway Server" is available in the Performance Monitor mmc as "gateway ...Show All
