• SQL Server Problem when launchin reportBuilder

  One of our Client is using our WebApplication (ASP.NET2). In this application it is possible to lauch reportBuilder to allow reports creation. We never have any problem with this feature except today when we tried this feature on one our client computer. Normaly when we tried this feature for the first time in a computer we get a window to allow us to install the ReportBuilder Application. So we juste have to click on run and then some plugin is installed and after that reportBuilder is working fine. When we tried to launch ReportBuilder for the time today on this computer we didn't have the choice to install the pluging but only to download it. So i've download it and put it on a folder.

• Visual Basic How to select and open excel files in VS2005. with FileDialog.

  Hi, I need to list and select excel files, and open them in code in a VS2005 application. I know the following code using Stream will not do this, but it may give an idea of what I'm trying to achieve. I have a simple form with a Button it, and want to select a file from the folder, unlock the file, so I can update an Sql table with the data in the excel file.

• Visual Studio Express Editions relays...

  Could someone point me towards some material on programing with the serial port or if someone saw a post on a site like hackaday that uses serial port programming. I am trying to be able to control 4 relays (or i can start with 1) over the serial port. or usb, you decide what the best thing would be to use. Thanks to all the people who post on msdn forums.. Average Joe Here's the datasheet for a range of popular RS-232 transceivers used in laptops. Short-circuit output current is between 10 and 22 mA. Don't worry about short-circuits destroying the chip, they've had built-in protection for many years now. This Radio Shack relay might work although it is pretty close to the maximum output current ra ...Show All

• Visual Studio Team System Forward integrating (parent-to-child) bug fixes always causes conflicts

  Hi everyone: I have the following branching scenario: BranchA - Version 1.0 of the product, currently in production, currently being maintained - Branch B - Version 1.1 of the product, currently under development (child of BranchA) Obviously, bug fixes in branch A need to be forward integrated into branch B. This works, but the scenario below is confusing, and can potentially cause devs to merge incorrectly: Branch V 1.0 into V 1.1 Make changes to code in V 1.1; file class1.cs Check in changes Make changes to code in V 1.0 (e.g. bug fix); file class1.cs Check in changes Merge V 1.0 to V 1.1; latest version Conflict window pops up => understandable, both versions of class1.cs have changed Merge the fil ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Beta2: 3D Object faces not appearing with CullMode=None

  CullMode is set to none, but faces are not being shown on the same object (simple cube), but you can see the object behind it just fine due to the transparent texture. Hard to explain, but these should help. I can't see any reason that some of the faces would just not appear with culling off. I hope someone can see a simple resolution here, or if it's a bug. Screenshot: http://www.cybra.net/gd/images/Beta2-SCProblem.jpg Project: http://www.cybra.net/gd/TransTest.zip Thanks, how would I do that I ran a quick search on the forum and only saw one other post discussing that, but not where to disable it. I assume off GraphicsDevice somewhere, but there's lots to look at. ;) ...Show All

• Visual C++ Event Confusion!!

  Hi all, I'm pretty new to the world of VC++ programming and I'm trying to implement a mousemove event on a picture box on a dialog. I can get the MouseMove event to fire if I add a message map etc to the dialog cpp file and header, but when I add a picture box, there doesn't appear to be a class file to add any code to for the MouseMove event. I'm a little confused, if the code goes in the Dialog cpp and header how do I tell it that it's the picture box I want the event to fire on and not the dialog box Please someone help, I'm totally confused. Cheers Pete OK, Im using VC++ version 6 (Only because it has classWizard which make creating classes easier) so I have a dialog box, by default it has two button ...Show All

• Windows Forms Value of databound text box can't be set programitcally

  I have a text box on a tabbed panel which is data bound to a SQL table.When the user clicks on a tab the corresponding databindingsource creates a new record through addnew() and then the value of a text box is set to a variable set in a previous event. I know the value of the variable is fine but I was wonder if there was any update or refresh command that I need to run to display the updated text. To make it little clearer here is a sample of the application : private void tbPayments_Selected(object sender, TabControlEventArgs e) { switch (e.TabPage.Text) { case "Cash Payment": cashBindingSource.AddNew(); receiptNoTextBox2.Text = MyData.GetReceiptNumber().ToString(); bre ...Show All

• Windows Live Developer Forums Firfox Polylines

  I'm trying to add a polyline for tracking of the previous location of mutiple objects. This works fine in IE(Of course) but on Firefox 1.5.0.4 on Mac and Windows all the lines are being put in one place instead of actually having the correct locations. The code is at http://www.wormley.com/t1.html The pushpins were added to illustrate the locations where each line should be(you have to zoom in, the tracks aren't very long) but both polylines are ending up near the left side in firefox. It still doesn't work without the pushpins. Thanks, -Steve Just to chime in here: I'm seeing the exact same problem. Works fine in IE, with Firefox the two polylines get placed on top of one another.
