• Visual Studio Reports

  Hi! How can I made the query parameters of my dataset be set as report parameters I have a report (*.rdl) that calls a dataset that have a query parameter (@param1) And I have the report in the report server. But it displays an error because it doesn't find the declaration of the variable (@param1). I think the solution is to put the query parameter as a report parameter... but How do I pass it to the dataset (*.xsd) Please help me! If the explanation of my problem is horrible please contact me and I will try to explain it better.... :) 1. Build dataset like: "select field1, field2 from table where field3=@param1" 2. ReportViewer control is connected to ObjectDataSource. Obj ...Show All

• Audio and Video Development Maintaining State - script vs markup

  I've got a new guy I'm training on HDi and he's asking the same questions I did when I first start coding in HDi. And I realize I never get definitive answers on the best way to maintain state. For example, it seems like you should be able to maintain the state of several buttons and menu operations in markup using state:value(). But I have never been able to get this work and the only solutions I've seen in markup (in production HDDVDs and samples) involve using dummy elements to hold a "value" for the state of the menu. Even Peter's example use this design pattern (see blog), and he prefaces his example with the same perception that my team does: this seems hokey/messy.

• Visual Studio Team System VSTE Crash on Rename of WebTests and OrderedTests

  Back on April 19, 2006, the following problem was posted regarding VSTE crash problems whenrenaming webtests. I didn't find any further thread information/answer/resolution/suggestion. I'm experiencing the same problem... but with not just webtests... but with orderedtests, as well. Is there a suggested solution available Tx dgorena_MS (Expert): Q: If I go into Solution Explorer and attempt to rename either webtests or folders that they are in, there's a 50% chance that VS just shuts down. Re-opening the project and showing all files shows that both the original and renamed files are there. A: Is this something that you can repro for any project or a specific project We definitely want to know the cause of this and help you ...Show All

• Visual Studio Express Editions DateTimePicker

  i am using the datetimepicker and save the value to a DateTime variable. I am then sending the data to a file. I do not want the time to be sent. How do i accomplish this I only want the date to be stored in variable date, not the time. DateTime date = dateTimePicker1.Value; thanks you can use the date time ToString() method to just get the date itself. Example: string theDate = date.ToString("ddMMyyyy");   this will just return the date format you are after. Here is a list of the string custom formats you can use to get the date time string back in the format you like: http://msdn2.microsoft.com/en-us/library/8kb3ddd4.aspx so your code could be: this.theDataTimePicke ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Buying Pre-made models for XNA

  What is the best source to buy pre-made models for XNA Does anyone know of companies out there that will make custom models on demand I would also like to know what the best meshing/modeling tool for XNA. We have been playing with Blender 3D. I have tried incorporating pre-made models from turbosquid.com and not all of them work. The ones in .x and .fbx format work fine, but most of the texture size are not in the factor 2 scale, and we might need to manually resize them. Thanks Kyle_W, we are an academic group at MIT and are working on an RFID simulator. We need to build accurate models of buildings, such as warehouses and retail stores, for our RFID enabled robots to move through. We might also need a model of a city. I ...Show All

• SQL Server SQL Reporting Services WS - check user input

  Hi, What is the best way of ensuring that users of a report entere data in all the provided input boxes I have written a vb function that checks the above requirement – but when I deploy my report and use a Reporting Services WS to retrieve the data the function no longer works.

• Windows Forms how to void the TabIndex property so labels cannot be tabbed through?

  Is there a way to void the use of the TabIndex property I have a form with textboxes and labels, but I don't want the labels to be included in the list of controls that you "tab through". I want to be able to tab through just the text boxes, and then when finished going through all of them, it should go back to the first textbox, rather than having to go through each label before doing that. Thanks! Ah, I forgot that you were talking about Label. By default the default TabStop for a Label is false, so it shouldn't be tabbable anyway. Also, Label overrides TabStp and marks it with Browsable(false) so it won't appear in IntelliSense. I guess the question is why are your Labls TabStops true in the first place ...Show All

• SQL Server Error: Number (1204) Severity (17). Running out of locks

  Hi, First of all, my apology. I'm not sure if this is the right SQL server forum. Moreover, this didn't even happen on SQL Server but Sybase 11.9. But I'm thinking that the same situation might happen on SQL Server and I can't find any Sybase forum to run this by some experts. I got the following error on a dev server: Error: Number (1204) Severity (17). SQL Server has run out of LOCKS. Re-run your command when there are fewer active users, or contact a user with System Administrator (SA) role to reconfigure SQL Server with more LOCKS The number of locks was set to 10,000.

• .NET Development Trying to pass parameters to my Windows Service but how?

  hi everyone, From my Service Manager built-in in MMC no problem at all because I can perfectly allocate both parameters in "start parameters" box but how do the same from NET START command Or even better, how from another VB application I've tried to do this: NET START "MyService", "sql1","Bd1" but it did not work. Let me know if possible do (at least) from DOS session. Thanks in advance for your time. I've seen sc utility but it doesn't support parameters either This has nothing to do with arguments. OnStart() should quickly return when being called. Usually, the only way to accomplish that is to have it start a thread to do the real work. ...Show All
