  I am trying to send a mail message. the body of the mail message must contain data picked from a web form, as an attachment. can anybody help urgent you would still use the above approach in regards to sending emails but in terms of sending all the fields with formatting (which fields ) then the best place to ask would be over at the ASP.NET forums: http://forums.asp.net as for formatting - what do you mean do you mean the input from textboxes I believe this can be done if you set the MailMessage object's IsHtmlBody = true property. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA Game Studio Express compatible with Visual Studio Professional

  Can't wait to get home and download XNA GSE but I'm concerned; will I be able to use it on a machine where I already have an installed copy of VS Professional I have another machine that I can use that doesn't have any developement tools on it but that would be inconvenient. I checked the FAQ and didn't see anything one way or another. Thanks in advance. Well you could always just create a windows application project, add the two XNA assemblies references and go on from there (done it with no problems), the installer needing visual c# express thingy was just a wierd mental screw up me thinks :) ...Show All

• Visual Basic How do I copy bitmap data to a buffer?

  I have an application that displays some images using PictureBox. There is a requirement to toggle between colour and monochrome or grey-scale versions of the image, so I've created a class derived from PictureBox that contains extra bitmaps that hold the various versions of the image, and then when the user switches between them, I just assign the relevant bitmap to the PictureBox. When the image is first loaded, the application generates the monochrome and grey-scale versions from the loaded colour version. This is where the problem lies. For each version of the image, I make a clone of the original, and then loop through X and Y, using GetPixel and SetPixel to change the colour based on a conversion formula. That also works ok, b ...Show All

• Visual Basic Serious Problem!!! Please HELP!!! Project does not allow changes in code or design

  Hi, I was working at my project (Visual Basic, Visual Studio 2005) and while I was making changes a message box came up asking something about reloading my project. I clicked it.. and since then (i think its from that time) my project doesn't seem to build the changes that I make. For example, I added a form and deleted another, and although the project compiles and runs, the deleted form is still there and the new one doesn't exist. I even added a simple line of code in the form load event of my starting form, to show a messagebox but nothing. I am stuck. Please help. I tried to create a new project and add the forms from the old one but nothing. The forms are empty. When VS ask you to reload your project, that means yo ...Show All

• SQL Server Package Validation Error : The package designer deletes the code from script task.

  While Creating a script task in Control Flow, I am getting "Package Validation Error". Here is the complete message: Error at Validate File and Load Data: The task is configured to pre-compile the script, but binary code is not found.

• Visual Studio Express Editions clicking a picturebox

  I have about 200 little pictureboxes that start simply white. When they are clicked they turn black. I'm using picture boxes because they are the only thing that can get as small as I need them. I'm hoping for a way that I don't need to re-write the code that many times. I've tried using Private Sub PictureBox1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click Me .BackColor = Color.Black End Sub But that changes all the picture boxes and textboxes and forms backcolor to black. I'm hoping there is some simple solution that I'm missing. Thanks for any insight. DMan1 wrote: Use a single click event for all of your picturebox ...Show All

• .NET Development WebClient File Download Problem

  Hi, I am trying to download files from the web using System.Net.WebClient. The program works fine and I am able to download the files for the first time. But, when I try to run again I get "An exception occurred during a WebClient request". This behavior alternates for each run. In one of the threads, I read that it was because of keepalive property being set to ON on the webserver. Is there anyway I can fix the problem by some code changes. Here is my code sample. WebClient wc = new WebClient(); wc.DownloadFile("http://someurl/file1.ext", "C:/myfile1.ext"); wc.DownloadFile("http://someurl/file2.ext", "C:/myfile2.ext"); wc.Dispose(); Any help would be appreciated.
