• Visual Basic FolderBrowserDialog causing debugger hang (Stop Debugger - required)?

  Hello; The following code is causing my application to hang (requires me to click Stop Debugger) to get the application to quit. Dim dialog1 As New System.Windows.Forms.FolderBrowserDialog() Dim result As DialogResult = dialog1.ShowDialog() Once the above code runs the system will not exit when I close the form, it requires me to click stop debugger. I am using Visual Studio Professional 2005 with SP-1. I have noticed this does not occur when I run this same code using another workstation (one from work). What could be the cause of this OK, your app is essentially identical to mine. There definitely should be no hang on the exit -- definitely a head-scratcher. Can you file a ...Show All

• Visual C++ Memory leaks created by the compiler/ run-time system

  I have spent nearly two weeks trying to find some memory leaks in a program I am developing. Initially I thought it had something to do with PlaySound (see previous post, 30 Jan 2007) but that was not so. I have now discovered some hidden memory leaks in C++ which I am happy to share with others. (Please note I am using Version 6.0. It’s possible these problems have been fixed in later versions.) The following code: CSize test = pDC->GetTextExtent(“ABCDEFG”); creates a memory leak. I thought that all memory allocated within a function (when not using ‘new’) would be deallocated at the exit, but this is not so. My best guess is this. GetTextExtent has two forms and the form used above needs a CString par ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. C++ or C#

  Hello, I am currently taking a class in C++ and I've always wanted to make games. I downloaded the c# XNA software. My question is: Can I use visual C++ instead of learning a new language (C#) to make games for the XBOX 360 and PC Or would it be better to go ahead and dive in to the new XNA software, and why is one better for gamming applications and / or learning to write games OK, thank you....so it seems I wouldnt be 'making a mistake' by learning C# and getting to it. Although I have created simple bussiness applications in C++, I've never made a game and deaalt with graphics and animation and such..is there any books or starter material youm would recomend that would step you through simpl ...Show All

• Visual C# [C++ to C#] -> Convert a char* to string

• SQL Server Insert image using clr stored procedure

  I tried to insert a row using a clr stored procedure where a field was a varbinary(max) and the data was a jpg file. The data was truncated to 8000 bytes. A similar T-SQL sp did not truncate the data even though the parameters were identical. With the clr sp I tried varbinary, variant and image for the parameter type. The variant gave an exception. The others worked but the data was truncated. I used sqlpipe.executeandsend. Someone asked elsewhere if the pipe had an 8000 byte limit but was told it had not. Any ideas Thanks, John By default Visual Studio limits sql strings to 4000 characters. You must add SqlFacet attributes to the strings you want to be different than that. For example to pass ...Show All

• Visual Studio Tools for Office VSTO Outlook 2007 Questions

  i have been tasked with developing a VSTO Outlook 2007 add-in application. The company wants me to start developing this right away, despite both Outlook and the VSTO still being at a Beta stage.

• SQL Server Dynamically change the sender email address on a SQL2005 Windows 2003 server 64-bit box using database mail

  We currently use xp_smtp_sendmail to send the emails on a sql2000 32-bit box. We are trying to move our databases to a new sql2005 64-bit box. One solution is to replace xp_smtp_sendmail with database mail since xp_smtp_sendmail does not work on 64-bit box. The only problem is that we need to change the sender email dynamically based on the query results and I don't know how to accomplish this by using database mail. Does anyone have an idea We are not restricted to database-mail solution though. Thanks for help.

• .NET Development Simple Reflection Question - Getting the class name?

  This is probably easy, I just stink at reflection and can't seem to locate the resource I'm looking for... I like to use Debug.WriteLine() in order to help trace events. What is particularly helpful is to know which Class and Function posted the Debug, so I include that in the text, something like this: Debug.WriteLine("MyClass:MyFunction:Fired."); Of course, I have to keep retyping the Class and Function name each time I add this to a new location, what a pain. So I figured it would be easier to use reflection to figure out what class and function I'm in. Something like this: Debug .WriteLine( MethodInfo .GetCurrentMethod().Name + "():Fired" ); That does a nice job of giving me the Function name I'm in. Now I just need t ...Show All

• Windows Forms Object Data Source and Control DataBindings Order

  When I add an Object Data Source and expand the (DataBindings) in the property page, I can select a property to bind to the control. The properties from the class appear in random order. If I use a DataSet instead the properties are in alphabetic order. It would be great if both could show up on alphabetic order! The object's properties display in alphabetic order in the Data Sources pane, so someone at Microsoft clearly wrote code to do it. Please consider this a feature request. Meanwhile, how could I get the properties to display in alphabetic order I'm guessing that a TypeDescriptionProvider might do the trick. What are the options, and what would you recommend I know properties can be bound using Drag-and-Drop from the Data Sources ...Show All

• SQL Server WROX Code Problem

  Hi, I'm pretty new to SSRS and VB.NET and was hoping someone might be able to help me understand why the following code fails when the click event outlined below is fired. The line highlighted in Red is the problem area and when this is commented out the event executes successfully. I've also downloaded the C# version of the code from the WROX site and this also fails. The code snipet relates to the windows application "RenderingVB" in Chapter 12 of their Professional SQL Server 2005 Reporting Services book. I've tried the WROX forum but there isn't a great deal of activity. Any help would be much appreciated.

• Software Development for Windows Vista Vista RC2: RasSetEntryProperties() return failed if non-admin

  Hello, System setup: Vista RC2. We have some Managed C++ code that calls RasSetEntryProperties() to create a phonebook entry in order to perform a direct connection through a modem device.
