• Visual C++ Floating point stack overflow

  My application works fine in VS2003, but in VS2005, it is producing an overflow of the floating point stack.  This seems like it must be a code generation error in the new compiler.  Has anyone else experienced this problem In the particular case I am looking at, I step through the instruction FLDZ in the disassembly window.  Instead of getting a zero in ST(0), I get 1#IND, and the SF and C1 bits are set in the x87 FPU Status Word.  The first time through this code it works OK, but this second time through, the FPU tags register shows that the stack is full before the FLDZ instruction. That document on the floating point model is excellent.  Thanks.  It turns out my problem is a code generation bug ...Show All

• Software Development for Windows Vista Is there any chance to write codes to set environment variables of command-line window?

  The goal I want to achieve is that when I open a command-line window, I run my exe, and then it will add a new environment variable or modify an existing one of the command-line window , and the enviroment should only be local (effective only in the command-line window). Further, I don't want a batch file to do this, I know batch file can easily do this, but that's not what I want. Any ideas Thanks! Environment variables are a per-process resource. Meaning, unless you're creating a child process you can only change the environment for the entire process. Use CreateProcess to provide environment variables to a new process. ...Show All

• SQL Server printing error

  Hi, some of my application users doesn't have Admin Privileges to their machines. When they try to print the reports, its giving a message "Unable to load client print control". Please help me how to solve this problem Can you login as an admin and print a report I believe that the first time you try to print any report, it installs the print controls. Then you can log off and let the user back in. This way, the print controls would be installed for the user the next time they need to print. Hope this helps. Jarret ...Show All

• Visual C# Object reference not set to an instance of object

  Hi all, I had created an array of labels and intend to add it to a panel. But I am receiving the above error once I compile it. Can anyone please explain Thanks for ( int nodes = 0; nodes < op_node.Count; nodes++) { op_node_name[nodes] = op_node[nodes].Name; Label [] lbl_arr = new Label [op_node.Count]; lbl_arr[nodes].Text = "Sample Label" ; Panel1.Controls.Add(lbl_arr[nodes]); } What he means is your code should look like the following: for ( int nodes = 0; nodes < op_node.Count; nodes++) {   op_node_name[nodes] = op_node[nodes].Name;   Label [] lbl_arr = new Label [op_node.Count];   lbl_arr[nod ...Show All

• SQL Server good matrix tutorial

  Does anyone know of a good matrix tutorial which shows a finished report and how the choices for Page, Columns, Rows, and Details map to a finished report Having a tough time wrapping my head around the direct impact, and for whatever reason, my sample data keeps triggering an "Out of memory" during preview mode. I'm experiencing this out of memory error too: I have one database which I can connect to, which gives me around 300 rows, and that's fine. However, another database which returns around 6000 rows throws an out of memory exception when I try to run the report. I'm guessing that a matrix report has to load all the data in to an internal list, and this is causing the problem. Seems a ...Show All

• Smart Device Development ppc stops on main()

  i am using vc++, with a smart device, to program a ppc. My problem is the windows engine runs just fine, but it runs all the time, without timeshare to my main() vc++ program. Winmain() and Main() are my only threads, both are suppose to start running at time "0". Main () does not startup and i can not thaw it. This has been a problem for 4 months. I can not program around main(). I would appreciate any help and input. No, you Main() is not supposed to "start at time "0"". There's only one entry point which starts and only one initial thread. You have to create another thread(s) in your code as needed. ...Show All

• Smart Device Development Soft Input Panel

  Hi, How to make the Forms resizable and shrink when you activate the Soft Input Panel Place a Panel (or any other container control) on the form. Size it that way so it fills the entire screen (Anchoring all sides will help as well) Add an InputPanel control to the form and add a event handler for the EnabledChanged event. In the event handler change the height of the panel based on the size of the SIP. Instead of placing your control on the form directly, place em on the panel you added. Sample: public partial class Form1 : Form { public Form1 () { InitializeComponent (); } private void inputPanel1_EnabledChanged ( object sender, EventArgs e) { if ( this .inputPanel1.Ena ...Show All

• Visual Studio Embedding shapes in v1

  Hi, First of all congratulations on getting v1 out. It's looking pretty cool! I have been trying to migrate a DSL I developed in the June CTP version, but I have run into some errors. A couple of examples are.. Error 23 A GeometryShape may not be parented on a GeometryShape. In the ShapeMap mapping State to StateShape, the parent element path leads to StateManager, whose mapped shape is StateManagerShape. Error 26 A ImageShape may not be parented on a GeometryShape. In the ShapeMap mapping EnterCommand to EnterCommandShape, the parent element path leads to State, whose mapped shape is StateShape. Basically my DSL is similar to UML statechart notation, but I want to be able to nest states inside one another hierarchically in ...Show All

• Windows Forms Install updates after the application start

  Has any one attempted to detect the app updates after application start inside the program Just wondering if application has updates, how do you apply the changes Do you close the application or is there an ApplicationDeployment method that does the update for you So far all my installations are all before application start and never done after the application start. Thanks. If this is a ClickOnce app you can use the System.Deployment.Application class to check for and download updates from within your application. After downloading update use the Application.Restart method to restart the new version of the app. For more info see: http://msdn2.microsoft.com/en-us/library/ms404263.aspx http://msdn2.microsoft.com/en-us/library/s ...Show All

• Smart Device Development Access to APIs in C#

  Can I use the Windows Media Player 10 activex control in C# I've researched the documentation and it seems to only be available in C++. Also, does C# support DirectDraw and DirectShow I need to use the camera api functions and allow the user to take a video, replay the video, and draw on the screen using the stylus. I need the drawing to persist on top of the video while the video plays (as with overlays, but I think most handheld devices don't support overlays). Thank you for the information.

I've had no difficulty using the WMP control on the desktop, but I can't seem to add the control to my pocket pc device for ...Show All
