• Visual Studio Express Editions Selecting a dataset from user input

  OK. I have an application that needs to look up various data via a dataview based on user selection of a listview and/or combobox. Obviously I can simply hard code the selections. However there has to be a way (I hope) that I can use the selection to form the dataset. For example: Suppose the user selects MachineA in the combobox not MachineB The hardcoded dataview would be Select Case combobox.selecteditem Case = "MachineA" dataview = me.MachineAdataset.table.defaultview IS there not a way to do something like this Dim strng as String = combobox.text dataview = CObj("me." & strng & "dataset.table.defaultview") Thanks. I dont know if th ...Show All

• Smart Device Development CF1 unable to detect VGA screens?

  I have switched from CF2 to CF1 and the following code System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height produces different values between CF2 and CF1 on PPC VGA emulator. In the CF1, the result is 320, whereas in CF2, the result is 640. Should this be the case You'd need to mark your application as DPI aware so OS won’t do pixel doubling. You would have to handle all resizing. ...Show All

• Gadgets Force user to the Settings UI window

  I have a gadget that requires some user settings before it can function. I'd like to check the settings and if they are blank, say something like "Click here to change settings". Then when the user clicked the link, I would like to open the settings window just as if the user clicked the little wrench icon. Right now all I can do is tell them to click the little wrench thingie and hope that they know that that means. Unless I'm overlooking something in the Sidebar Gadget Object Model , I don't see a function for this. Does one exist It would be nice to have a System.Gadget.Settings.show() function to launch the settings UI. Donavon Sorry, but this is not supported. It's a better user experience to pick ...Show All

• Software Development for Windows Vista What is the difference between WCF's one way operation and .NET 2.0 asynchronous web service call?

  The one way operation is really new to me. Anyway, I don't see the differences from asynchronous web service call in .NET 2.0. 1. If i declare an [OperationContract] method, make it one way, this should be similar to making a regular void web service and then from the client, I call the asyncronous method in the proxy and then in the asyncronous callback I simply leave it blank. What are the differences 2. If i declare an [OperationContract] method, make it one way and then I declare a CallbackContract to send the message back to the client. What is the difference between this scenario and calling an asyncronous method in the web service proxy that returns output 3. Again, for one way methods, because the client does not wait for ...Show All

• Windows Forms hiding control changed its location

  I have a control added to a groupbox and another control added to the main form which have the same location. The two controls can "alternate", that is, when I click on the first it is hidden and the second is shown and viceversa. The application starts with the second control hidden. My problem is that when the first control is hidden it changes location and the new location is eqaul to the old location plus the size of the second control plus two. What's wrong You can't have a control as a child of a group box have the same location as another control that isn't a child of the group box (e.g. a child of the form). The location is the x and y position of the control relative to it's parent. Mayb ...Show All

• SQL Server RSClientPrint - Printing Issues with page margins and orientation.

  Software used. RSClientPrint object, SQL2005, RS2005, VS2005. I am working on a project with a few hundred reports with varying page margins and orientations. According to the MSDN documentation, the RSClientPrint object retrieves the page margins and layout are from the RDL by default. "You can initialize the Print dialog box with margin and page values of the report. By default , the Print dialog box is initialized with values from the report definition." This doesn't appear to work. I have verified that the RDLs I'm testing with do have the Margin attributes, and the pageheight, pagewidth attributes. Previewing or printing the report show that the margins were not used, and the page height, width didn't set the orientation ...Show All

• Visual C# Why do we always use int? Why not short?

  Just curious... Why do we never use short when working with numbers I mean in simple contexts like for instance in a loop, or other i++ situations.  How often do you write a loop that goes more than 32K iterations "32K ought to be enough for anybody"- at least in most situations. I just have a feeling that short would take up less resources/increase performance - but probably so little that it's not worth the strain of typing to letters more (short/int) Is the convenience of typing only 3 letters, the only reason Actually using short can lead to slower code in some situations. The reasons are (the CPU stuff applies only to x86, I don't know exactly what's happening on a x64). a) the " ...Show All

• SQL Server Copying Database without data

  Hi, Does anyone know, with either the Apr or Jun CTP, how to copy an entire database without the data   I know to use the SSIS wizard to copy tables with data, but there seem to be no option to not copy the data. Thanks. BTW, There are some issues with this task in the June CTP that have recently been fixed and will not be available until the next CTP. This solution will probably not work for you until you can get the version with the fixes. ...Show All
