• Visual C++ Managed array of pointers to elements in another managed array

  Hello, I have some problems using arrays (system.array) in managed code. I have a two-dimensional array available and I would like to sort the values in this array by making a second, jagged array of pointers to the elements in the first array. However, there are some problems: the first array is of course declared on the managed heap. Pointers to elements in that array can change as the CLR rearranges the heap. The solution to this is could be an interior_ptr (which makes sure the pointer is updated when the heap is rearranged) or a pin_ptr (which makes sure the 'pointed' part of the heap isn't rearranged). The problem is that both pointers are only declared on the local stack: it is not allowed to form an array of pin_ptr or inter ...Show All

• Visual C# Compiler Error CS0570 from C++ defined property

  Compiler Error CS0570 Does anyone understand error CS0570 'class' is not supported by the language This error occurs when using imported metadata that was generated by another compiler. Your code attempted to use a class member that the compiler cannot process. The code being called was written in Managed C++ paraphrased like so: public ref class FilePath { ... [MyPropAttribute] property int Name { const int get(); } ... }; The attribute [MyPropAttribute] is defined like so: [System::AttributeUsageAttribute(System::AttributeTargets::Property)] public ref class MyPropAttribute: public System::Attribute {...}; When I try to use the property in C# code I get CS0570, but see no document on how to get around t ...Show All

• Visual Basic Dynamic Timers

• Visual Studio Team System Cannnot Connect to TFS

  I have TFS setup in a Single-Server environment on a server within my companies domain. Today, I tried to connect to TFS and received the following error in an alert box: Team Foundation Server TF31001: Team Foundation cannot retrieve the list of team projects from Team Foundation Server <servername>.

• SQL Server Stored Procedure Input Parameter Drop Down

  Hello, I have a stored procedure which has input parameters that must be entered manually. When I run the procedure from SQL Server Mgmt Studio, I type the entries into the appropriate entry boxes that appear. Is it possible to create drop down lists that include the allowed values, such that when I run the procedure, I can select the values from the drop downs, instead of typing them in each time Thank you. Unfortuantely, the functionality you seek is more suited to client applications, and SSMS is not intended to be a client application -more of a management tool. You could relatively easily create an Access or Visual Studio based application that would have the functionality you desire. But yo ...Show All

• Windows Forms Application Lockups with VS 2005

  The application is built in VB.NET in VS2005. It builds fine and the exe is installed. The application exe works fine but will lockup on occassion. For example, If I go away from the application for about 20 minutes it will lock up. If a screensaver starts it will occassionly lockup. Just this application and not any others. Any ideas Start it with a debugger and walk away for 20 minutes. Hit Ctrl+Break. If you want a better answer, you'll have to give us a *lot* more details. ...Show All

• SQL Server Configuring Multiple Precedence Constraints in DTS

  I have a simple DTS package that consists of two steps (simple SQL tasks) plus a Failure package and a Sucess package. Using the designer, I have each of the steps going to the Failure package using the workflow On Failure event and the first step going to the second On Success then the second going to the Success Package On Success. Unfortunately, having the two events point to the same failure process results in the workflow developing an AND between the two (e.g. if Step 1 fails AND step 2 fails execute the package). So my question is how do I change the logic to an OR so that if either step fails the Failure package runs In the alternative, do I need to have a copy of the failure packge for each step for which I want to handle a ...Show All

• Smart Device Development Accessing textbox from child form

  Hi All, How can I access a textbox in Parent form from a child form in .net compact framework. I have a parent form that is already loaded and there will be a button in parent form that will activate and show the child form. The child form will then need to populate the textbox in parent form. How can I do this in c#, this scenario is very easy in vb6. Any help is appreciated. Many Thanks. There's several ways of doing this, but the easiest is to pass a reference to the parent into the child form when you instantiate it (just pass "this" into the constructor). Obviously you'll need to create your own constructor for this and also make sure you set the access modifier of whatever you need to edi ...Show All

• .NET Development Interop Thread Leak?

  Hi, I'm hoping for a few pointers for tracking down a resource leak. I developed a VB 2.0 indexing application which is using FileNet's Capture COM objects and we're occasionally seeing a fairly serious leak. It doesn't appear to happen consistently (one user has never had one and I can't seem to reproduce it in my test environment), but it does occur regularly in production. I've been using various tools to poke around in a mini-dump (w/ full memory) and I've seen a few potential problem areas, but I can't seem narrow it down any further. Using PerfMon I found that the leak appears to be in private unmanaged memory. When I open the dump in WinDbg, I get this message: This dump file has an exception of interest stored in it ...Show All

• Windows Forms Question about accessing properties, methods from a user control

  Hello! I have a problem which is frustrating me. Why won't the roperties and methods that are inherited from my custom user control work on my Win Form I have declared the properties and methods as Public and Intellisense "sees" the property if I call it from the Form. But, the frustrating part is that the property does not work. It is a simple property that changes the string value of the text on a label. The label's container is a ToolStrip. Here's the property: Public Property DisplayApplicationStatus() As String Get Return Me. label1.Text End Get Set ( ByVal value As String ) Me .label1.Text = value End Set End Property As I stated earlier, VB.NET "sees" ...Show All

• Visual Studio Team System Customize Build Summary

  Hello All, I have customized my build to execute several task. I also use the Message task to add some trace in the log file. Note that all my tasks are executed in the AfterComplete task but I can move them. Is it possible to add some new lines in the existing Build Summary so I can directly see some output without having to open the log file Thanks, Swaha is correct that the GUI itself cannot be customized. You can add your own custom build steps from a custom msbuild task. Aaron shows how to do that in http://blogs.msdn.com/aaronhallberg/archive/2006/08/29/730447.aspx . Buck ...Show All

I have another procedure that is trying to insert that data back into a table, but when I perform the insert, it doesn't appear that the data is decoded properly.  When I look at the original data in the IMAGE field compared to the data I just inserted, it is different.  My insert looks something like this: INSERT INTO TABLE SELECT * FROM OPENXML (@DocHandle, 'Cases/Case/Illust_Illustration') WITH( IllustrationID UNIQUEIDENTIFIER '@IllustrationID', InputData IMAGE '@InputData', ResultData IMAGE '@ResultData') I saw this post ...Show All
