• Visual Basic sum of numbers

  Hi Im trying to create a program that when btnEnter is clicked an input box appears that asks the user to enter a positive integer value. When the OK button on the input box is clicked, a message box should appear with the sum of all of the integers from 1 to the value entered by the user. Here is what I have so far but I'm stuck: Dim userinput As String ' User Input Dim sum As Short ' To hold the sum Dim count As Short = 0 ' Counter initialized to zero Dim userNum As Short ' converted user input userinput = InputBox( "Enter A Number" , "Number" , "10" ) Do While count <= 0 userNum = userinput Loop MessageBox.Show(userNum) End Sub ...Show All

• Visual Studio Express Editions Compute Column in DataGridView Control

  Hello, I am building a pretty common control where the user enters the sale price and the quantity desires, then a column should sum the total price for that item. I have a form with a DataGridView control called "DataGridView1". It is bound to a table adapter which includes a column called "LineTotal". The other columns that should be multiplied together are called "SalePrice" and "Quantity". Many people have pointed to using the Expression method/property of the DataColumn object. I am confused as to the difference between a DataColumn and the DataGridView control. As a test, I wrote the following code to try out one approach. The column is added to the datagridview control, but it is a ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. HLSL shader(s) using CPU instead of GPU

  I am using D3DXCreateEffect to create a vertex and pixel shader HLSL effect. The process I use to create and activate the effect is the same every time, I am only changing the pixel shader code, and here's what happens: My program renders about 50 fps generally with CPU usage around 4% and when I do a trivial RGB to BGR color swap with the following shader, this usage remains: PS_OUTPUT RenderScenePS( VS_OUTPUT In ) { PS_OUTPUT Output; // Lookup mesh texture and modulate it with diffuse Output.RGBColor = tex2D(MeshTextureSampler, In.TextureUV) * In.Diffuse; float r = Output.RGBColor.r; Output.RGBColor.r = Output.RGBColor.b; Output.RGBColor.b = r; return Output; } So with this shader the rendering does a dynamic RGB to BGR swap ...Show All

• .NET Development Email Proxy Error with MailMessage

  Hi, I'm using VB .Net 2005 and am experiencing intermittent email proxy errors using the System.Net.Mail.MailMessage class. Shortly after sending the email I receive the following error message from the Symantec email proxy: “Your email message to (recipient) with the subject (subject line) was unable to be sent because the connection to your mail server was interrupted. Please open your email client and re-send the message from the Sent Messages folder.” Additionally, the error code that is displayed in the Symantec error window is 1003,9.

• Software Development for Windows Vista display interlaced video

  hi, I have a HDTV capture card that always combines two fields into a frame, i.e., it will generate a 30fps video at 1920x1080 for a 1080/60i input. The interlacing effect is very noticeable in the video render. Is there any existing de-interlacing filter for DirectShow The only one I found online (from alparysoft.com) does not work with HD (it seems). Note that I need a real-time solution. Ideally, I would like to display the video at 60Hz (instead of dropping half of the resolution). Given the 30fps input from the capture filter, is there anyway to "double" the frame rate in a filter graph Finally, a simple question about graphedt, is there anyway to show the actual video format being used in a filter graph through the UI I alw ...Show All

• SQL Server Dataset filtering... how?

  Hi all, I want to create a summary page for one of my report, depending on a parameter, I would like to filter the dataset before creating the summary fields. I cannot figure out how to perform this filtering, my approach has been to insert a Table control and map it to my dataset, then try and do some filtering via the properties. When i then put something like =sum(Fields!Sales.Value) into the header (such that it is shown only once, not repeated), I get the sum for the full dataset, not the filtered one. Please help, is there any easier way todo this Lastly, I can't filter at the SQL level as the dataset is being used to populate a chart below the summary. Advice welcome. Please help Taz Put the filte ...Show All

• Visual C++ Edit and continue does not work (for me) with VC2005

  Since "up"grading from VS2003, I have been unable to use edit and continue. Whenever I try, I get the error message: "Project : error PRJ0046 : Could not spawn command line because the one specified was empty." Are there any suggestions about getting this to work I'm very surprised that VC2005 doesn't just work out of the box. (This was never a problem with VC2003.) Apart from the scenario with a mapped drive, there must be some other problem, because we can't use edit and continue too here although we never had source code & project on a mapped drive. I couldn't yet figure out the root cause for our problem here, but it's definitely not the "mapped drive problem&qu ...Show All
