• Visual Studio August CTP Visual Studio 2005

  Hi,   I installed Augist CTP of VS2005 and it also does not have the Microsoft.VisualStudio.Package.Project.dll. hence how do I build my VSIP packages referencing Microsoft.VisualStudio.Package.Project.dll. Posts on this forum indicated that August CTP of VS2005 worked fine. Thanks, -K  There is no version of the SDK with package.project for RC. You will have to go back to one of the SDKs that supports B2. July or Aug. But, that wont be much help because it will depend on an assembly that is no longer part of the product. Really, its best to wait the 2 weeks until our Oct CTP is out. ...Show All

• Windows Forms A Memory problem related to Window size

  After my program (a WinForm app) started, it cost about 70MB memory(from statistic of Task Manger). However, after I minimize the main window, it changed to 5MB, then I restore it to maximized state, it cost about 17MB memory. In all situation, the virutal memory cost is the same. Could anyone explains this Thanks! Hi Lei, The behavior you're seeing is actually true for all Windows applications, not just .NET applications.  You can find a decent overview of what's going on here: http://www.itwriting.com/dotnetmem.php -Shawn ...Show All

• Visual Basic Displaying Key / Value Pair in A ComboBox

  Hi Everybody Call me a little bit dumb but I have a problem in VB2005 that I cannot solve. I have a Field in a Database Table (called AddressType), that stores a tinyint value. There are four valid values allowed (1 or 5 or 10 or 20). Each of them has a different meaning. Now I want to display a databound ComboBox on a userform, where the user can change the Value. So far so good, but the key Values are not very descriptive, so when the user drops the Box down, he sees values 1,5,10 and 20 that I have entered in the Items-Property of the ComboBox. What I am looking for is that I can display a descriptive Text for each of the p ...Show All

• Visual Basic Which Control did I RightClick on?

  hi all... Is it possible to find out which control a user rightclicked on and show the name of the control in a messagebox For example I have three buttons on a form and a contextmenu that is used in common with all the buttons. When a user rightclicks on a button the context menu is shown. Kind of like the "Whats This" menu in MS Apps. So instead of writing a rightclick event for all of the controls on the form, I thought that if I could find the name of the control that the user rightclicked on to open to context menu, I could show the appropriate response. Is there a way to find if a coordinate of the mouse click falls ...Show All

• Windows Forms Checking for a null entry in a textbox

  Lets say I have some code and I want to check to see if the user has not entered anything into a textbox; how do I do this In order for some code to work the textbox should contain a number, however, the user may not have entered the textbox yet. The value of the textbox is used in a calculation so I need to be sure the textbox does not contain a null. I have tried a couple of differnt lines of code to check for a null value but they have not worked. What is the right syntax Does C# consider "" as a null In VB you can move to a text box, put something in it, take it out again and the ...Show All

• Visual C# C# --> C++ (malloc not working!?!?)

  Hi Using dllImport to call a simple c++ dll. Below is a toy example of what I am attempting. There are several issues with the code you posted. 1) Your function is accepting an array of face pointers. Do you really want to dynamically allocate both the array and the elements within the array It seems like you should instead use an array of face objects. 2) On the C# side you should use an array of face pointers instead of an IntPtr. Eventually you'll probably want to work with the objects so an IntPtr doesn't help you any. 3) You are passing a null pointer to the function but the function only returns a value so you shoul ...Show All

• .NET Development ListBox magically disappears

  If I have a listbox that is databound to a sql database and the width/height is either set to a static value or no value then it displays correctly. Now, if I set the width/height to 100% it disappears both during design time and run time.  I just want to set the listbox so that it fills a table cell. Thanks for looking dave I'm guessing this is a webform application since you are setting the value to 100%. Is that correct   Try creating a stylesheet with a style class of 100%, then setting the CssClass of the document to the stylesheet class you just created. It may work a little better for you. ...Show All
