• Visual C++ EVC++ unicode problem

Like I said, it's a matter of seeing which "parts" are available and piecing them together. ...Show All

• SQL Server Webparts connection to sql 2000

  Hi everyone, I'm trying to get webparts working with an sql 2000 database. I managed to get a database up and running using the aspnet_regsql.exe utility, enable forms authentiation, and user registration using asp 2.0 controls. Despite this success I seem to be getting a connection error when I try to display any page that has a web parts control. My thought is I need to specify a connection in the web part manager or some file other then the web.config. Here's the error I get when I attemp to display a page with a webpart. Server Error in '/myFirstApp' Application. -------------------------------------------------------------------------------- An error has occurred while establishing a connection to the server.

• Visual C# check valid path

  Is there away to check a valid DOS path in c# ex: if the user types zzz:\test.txt and the path is invalid, return error message.   using VS2003 .NET1.1   Thank you, using File.Exists to check path validiy is a wrong idea and should never be used. It says MSDN here: http://msdn2.microsoft.com/en-us/library/system.io.file.exists.aspx See Under Remarks heading. You can use System.Text.RegularExpression.Regex class to do this but for that you need a Regex string which i belive can be easily found through google. Try something like this File path Regex, Path Regex etc. You'll need to write code like this: Regex fileRegex = new Regex(regexStringHere); Match mat ...Show All

• Visual C# Using a class as a parameter

  Hi there! I have to pass a class (not an instance) as a parameter to a method, and I have no idea if I can do that -- tried various things and it doesn't work. It should behave like this: I have a BaseClass. Another ChildClass inherits it. The ChildClass has a method (or Property), static or not, that returns a class. The BaseClass has quite a few methods where this class is needed (to invoke static methods on it), so the BaseClass invokes the "GetClassINeed", which returns the static class and then uses it. The reason I need it is that I have about 30 of those ChildClasses, and they all need those methods defined in BaseClass. I don't want to add them in all of them if not needed. Also, to create instances of that Cla ...Show All

• Windows Forms ClickOnce through Proxy with Authentication

  Hello, I have a problem with ClickOnce Deployment: My app runs on Windows Server 2003, IIS 6. In my university we have a proxy which needs authentication, and if I click the .application file, first there is a login window for the proxy, then the window ("verifying application...") comes up, but then there is an error message, saying that the file *.application can not be downloaded. In the log file is an entry: the server is unreachable, so I think the process which downloads the .exe and the other .dlls don't know the proxy authentication information. what can I do, to run the application behind such a proxy thanks, marco I just came accross the same issue, I then googled and found this solution. so I thought I would share it.

• Architecture Error Codes

  Hi , I need your opinions about whether to use a global return code for each method in my application or let every component throw its exception and use the upper layer to handle it. Example : public RetCode ABC () { If(…) Return RetCode.Valid; Else Return RetCode.Invalied; } OR public void ABC () { If(…) … Else Throw new Exception (…); } Thanks it's a best practices NOT to throw Exceptions but write code that catch common errors. So "Throw new Exception (…);" is n't the best way. ...Show All

• .NET Development Power consumption class?

  Does the .NET framework has a power consumption class or something like it , is because i want to know how much power (in watts) my pc spend, but i don't know if this is possible Hi, No, you don't have. The main reason is because that interface is not standard yet, this information is usually published by your motherboard manufacturer. If you check the website of your manufacter maybe they will publish the interface to their own API. Usually they publish information about consumption, fan status and temperature. Microsoft is trying to standarize that information using WMI (Win32_MotherboardDevice.DeviceID="Motherboard") but the information is not published yet. Hope this helps! Cheer ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Sprite scaling and blending

  OK, I've searched through a couple posts here and didn't find anything that fixed the problem. I'm scaling sprites to draw GUI controls and I'm getting funky results. Here's what I get (blown up 6x to show the problem). I'm drawing the box in chunks - upper left 4x4 pixels, upper right 5x5 pixels, left border, right border, lower left 4x4 and right 5x5 pixels, and upper and lower middle sections.I don't think I have to explain what the problem is.  I've tried setting texture filtering, destination blending, but nothing seems to affect it. Here's the sprite I'm using to draw. Maybe I just need to get some sleep. That makes sense if you try to stretch the entire texture, but what I don't quite get is why specifying a single pixel ...Show All

• Smart Device Development Trouble with Threading on Motorola Q Smartphone

  I'm having some trouble with threading on a Motorola Q Smartphone which runs WM5 as you know. I have a C# program that I've been running under XP quite successfully. When I recompile it (with a different UI of course) for the Q, the threads to not start. Here's a code snippet... _thread = new Thread(new ThreadStart(Receiver)); _thread.Start(); which is executed in the main thread and where Receiver is: private void Receiver() { ... } I have some debug output that dumps messages to a text box on the display. The message dumped by the thread when it first starts never makes it to the display. Any ideas why this simple code would work under XP but not on a Q Thanks, FM I wou ...Show All

• Visual C++ Float Dot Product Template Optimization Problem

  I've been trying to get VC 2005 to optimize following piece of code C++ to the point that it is as fast as the equivalent in C.

Say I have a list of records in a table: Product Cost Active hat 1.00 false coat 2.00 true I have a DataGridView that shows purchases from a purchase table: Date, ProductID, Buyer Is there a way to have a DataGridViewComboBoxColumn show only active items so that a user can only select active items in the puchases datagridview, but when they click a purchase from long ago when an item was active they have the ability to pick that old(unactive) item or a new one for an update. Basically if I just have the ComboBoxColumn bound to a dataset with just active items, the datagrid will fail to load cause old purchases are not in ...Show All
