• Windows Forms TreeView Levels - Not going deep enough

  Hello all I'm suffering a little with the TreeView control. My problem is I'm wanting to create a dynamic category list that company survey's will be filed into. My database has a table for categories; each with an ID, Name and ParentID (ParentID is null if its a root Category / Node). Also each survey has a category ID it should be filed into. When the categories are pulled from the database I test to see if its got a ParentID, if it doesn't I want to add it as a root node, otherwise I want to find the node it should be a child of at add it to that. There in lies my problem. I can't get the TreeView to find any nodes past layer 1(i.e. Root->SubCategory). I have tried the Nodes.Find method but can't search lower ...Show All

• .NET Development Microsoft Oracle .NET Data Provider Performance - repeated internal SQL

  Hi, We are noticing several similar SQLs (listed below) which execute many thousands of times per day. The SQL in question does not access any application tables, it accesses the Oracle data dictionary to retrieve metadata, which is essentially static in this context. On one particular day the SQL is issued some 24,024 times, performing 401 million block accesses and consuming 2,080 seconds of CPU. Our concern is that as our transaction rate increases that this SQL may become a performance bottleneck. I'm wondering if there are any configuration settings within ODP or application coding guidelines which may allow the SQLs to be issued once and the results held locally for re-use I have read about connection pooling and statement caching. ...Show All

• Visual Studio 2008 (Pre-release) Centering WPF Window over a Win32 owner

  Hello all, I'm attempting to center a WPF window over an HWND. I figure this would be fairly straight forward. Using XAML I set WindowStartupLocation="CenterOwner". Then using WindowInteropHelper I set the WPF window owner to my hwnd (obtained by AfxGetMainWnd()->m_hWnd) then launch the window using ShowDialog. This does not achieve the desired result. The window is not centered over my main app window, however it is displayed on the correct screen (dual display environment) where prior it was not. Any ideas why this behavior If I cannot get this method to work then I'll simply pass in the center of my main app window in screen coordinates and work from there. Thanks, Jamie The solution I ...Show All

• Visual C# Configuration Files - Winforms .NET 2.0

  I'll explain the situation We have in our solution 6 projects, One is the winform gui APP which has it's own configuration file. Then there is another project which is the Data Layer and this also has it's own config file containing the connection string which is in the Properties.Settings are of the project. This is new to me so bare with my poor description I also joined the project later on. The problem is now we are deploying the project only one application config is deployed and it doesn't contain the connection string as its the application config. It seems the connection string is 'inside' the dll generated by the DataLayer project. No one here wants to fix the problem as such what we want is a way of accessing t ...Show All

• Visual Studio Unable to debug unmanaged C code

  Hi, I have a solution in VS2005 that comprises of a main vb.net project and an unmanaged C DLL, the linkage being via dllimport. I have my vb.net project set to allow debugging of unmanaged code and my C project set as mixed, but no matter what try I cannot get the source displayed when I step into the C DLL. Any ideas The only pdb file I have is a vc80.pdb so I'm guessing I've missed something in the compiler options, I';ve tried both browse debug and program database debug. But in both cases the vc80.pdb cannot be loaded with the error "the symbol file does not match the module" Steve ...Show All

• Visual Studio 2008 (Pre-release) Problems loading a stream into a RichTextBox (via a usercontrol)

  Hi,   I have a WPF application which has a window1.xaml and usercontrol1.xaml files. In my usercontrol xaml file, i have a richtextbox, and in my window file i have a file open menu bar. On click on the file open, the open file dialog box should open and the target of the file contents should be the rich text box. I have add the logic to open the file dialog box in the load file function within window1 class. After getting the filestream object, I am calling a property in the usercontrol class which sets my filestream object in the user control. I then call a usercontrol function which has the following code: range = New TextRange(mainRTB.Document.ContentStart, mainRTB.Document.ContentEnd) range.Load(fStream, dataFormat) ...Show All

• Visual Studio Team System running team explorer client as a stand-alone app with vs2005 installed

  Hi there Is it possible to run the team explorer client as a stand-alone app even though vs2005 is installed I'm using codeplex.com for my xna project, xna is visual studio express only, and team explorer isn't integrated into express... I'm aware of the command-line option.. I am pretty sure that the Express editions are sandboxed, meaning you can have multiple express editions and a Visual Studio 2005 edition installed on the same machine. If you install Team Explorer it will create a standard Visual Studio 2005 shell with just the Team Explorer bits in. Sadly, It still means that you have to do source control in a seperate application though - but at least it is a GUI. Hope that helps, M. ...Show All

• Visual Studio Express Editions how to populate label on different form.

  I'm trying to populate a label on from. The value for this label is coming from another form which opens up the active current form where the label resides, is this even possible and if so can someone explain how to do it using the C# express designer. you need to have a reference/instance of that form in question, and then access the label property either by making the label control public (so its viewable/accessible by the caller class(es)) or create a public property which can get/set the label property. Example of accessing other forms/controls: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=765625&SiteID=1 same thing would apply for a label, except you just change the properties appropriately. so, you want ...Show All
