• Game Technologies: DirectX, XNA, XACT, etc. using DXUTTextHelper to output a string

  I'm extremly new to Directx programming, and i've tried everything to get a std::string to output onto the frame. Hopefully you guys can help. I have it so std::string GetDetails() {...} returns a string (constructed with ostringstream, if that really matters) and returns oss.str() at the end. but I can;t figure out the conversion between std::string and wchar_t or WCHAR*. any help would be amazingly (thats right) helpful. Thanks. Use wstring instead or convert the string to a wide character array using a wchar_t array that can hold the data MultiByteToWideChar(CP_ACP, 0, wideString, -1, charString, stringLengthPlusNULL); wideString[stringLengthPlusNULL-1] = 0;   ...Show All

• Windows Forms Looking for an editable control that will give the same functionality as the listview

  I have overridden WndProc for a listview to prevent the columns for resizing. When the form is loaded, the cursor changes to the "hand" icon. How do I retain the normal cursor You prevent the WM_SETCURSOR message from reaching the control. That prevents the proper cursor from being selected. As an alternative, try implementing the ListView's ColumnWidthChanging event: Private Sub ListView1_ColumnWidthChanging(ByVal sender As Object, ByVal e As System.Windows.Forms.ColumnWidthChangingEventArgs) Handles ListView1.ColumnWidthChanging e.Cancel = True e.NewWidth = ListView1.Columns(e.ColumnIndex).Width End Sub That prevent the columns from resizing (you could be selective about it!) but sti ...Show All

• SQL Server Help with setting Algorithm Paramteres

  I was walking through the Text Mining example - which at one step required me to set Algorithm Parameters - MAXIMUM_OUTPUT_ATTRIBUTES=0. When I tried that the project would not build giving an error - Error (Data mining): The 'MAXIMUM_INPUT_ATTRIBUTES' data mining parameter is not valid for the 'XYZ' model.

• Visual Studio Express Editions C# vs ASP?

  Hey guys, maybe you can clear this up for me what is the difference between C# Web Projects and ASP.NET I am a little confused, I thought c# was for desktop apps and ASP.NET for web. Is this incorrect Thanks. ASP.NET is a web platform really where you can use C#/VB.NET as code behind. Both languages (C#/VB.NET) can be used for either desktop or ASP.NET development. The only difference is the "platform" - one is desktop client and the other is web (ASP.NET). You can use both or one or the other language in ASP.NET or even desktop client applications. ...Show All

• Smart Device Development How to determine if phone has SMS capability?

  Hi. I am using VS2005/VB.Net and CF2 to write applications for Windows Mobile 5 Smartphones. I'm developing an application that relies on the phone having the ability to send and receive SMS message. I believe (but I could be wrong) that in some countries, and/or with some network providers, that the ability to use SMS is something that must be "turned on" by the network provider and/or setup within the phone. Therefore, I would like my application to be able to confirm that SMS is enabled and working on the phone, and if not, inform the user appropriately, rather than the user thinking that my application isn't working as intended. So, is there a way to programmatically determine if the Smartphone has the ab ...Show All

• Windows Forms interacting text boxes & events question

  hello: I have a user form in vb.net 2.0. When a user enters a price in one of 10 price fields, their corresponding percent fields and dollar fields(which are read only fields) are computed based upon the change in price. These computations involve a cost and a quantity field also on the form. In addition when either the cost or quantity fields are changed, all read only fields of the 10 price fields must change since these computed fields involve cost and quantity. So I have an event each time a price is changed to compute that price's read only fields, and I have an event to change the read only fields of ALL the prices if the cost or quantity fields are changed. I was thinking of putting these in the validating event routines ...Show All

• Commerce Server CS 2007 OrderGroupCollecion to PurchaseOrder with BizTalk2006 - best practice

  Hi I am querying CS 2007 with an OrderQuery from within Biztalk 2006 and this returns a group of Purchase orders. My question: As i only want to process 1 Purchase order at a time should / can i envelope the OrderGroupCollection within a receive pipe or should i use a looping map once the message has arrived in the Orcastration Thanks in advance Simon Hey Glyn, How and where are you splitting the OrderGroup collection Are you splitting on the "<PurchaseOrder>" node It "sounds" like you are splitting it at the OrderForm level and BizTalk is trying to resolve that message against that schema, which doesn't exist out of the box. If you are splitting against the PurchaseOrder schema then you ...Show All

• SharePoint Products and Technologies How to get the corresponding english error message text?

  Hi, I'm getting a german language error message on a german installation of MOSS from a listview web part. I can't find any topics in google et al. with this message, but trying some translated words didn't help either. How can I get the corresponding english message Do I have to install the english language pack Thomas I doubt if that will help because as far as I know the error messages are based on the language of the installation rather than on the language of the language pack. In other words (if the above is true) what you should be doing is installing the English language version of MOSS 2007 (for the "correct" error messages from KB article and Google use) and then in ...Show All

• Visual Studio 2008 (Pre-release) Data Binding and element serialization.

  Hello, I would like to achieve following behavior: 1) I would like to set binding to some element property at runtime; 2) After that I would like to serialize the element to XAML and still have the binding available there; I.e. after setting a binding to property "Height" of the StackPanel element and serializing the element, I would like to have output similar to this one: <StackPanel Name="StackPanel1" Height="{Binding Path=MySourceProperty}" ... /> I already tried several ways: 1) Binding binding = new Binding(); binding.Path = new PropertyPath("MySourceProperty"); BindingOperations.SetBinding(StackPanel1, StackPanel.HeightProperty, binding); Serialization produces o ...Show All

• Visual Studio Unable to create a new DSL project from Visual Studio

At first, after the project is unfolded I get the error message box saying “ The method or operation is not implemented” . When I press OK, I can work.
