• sweet_salt Processor optimized compiler

  Hi all, I want to improve the performance of my application by compiling my application with a processor optimized compiler. Is there a vb.net compiler optimized for Xeon processors Now, I know that the vb compiler compiles the code into an intermediate language file. So I can’t actually see any improvements here, or am I wrong That’s why I think to use ngen.exe to pre-compile my application assemblies. Is there a special ngen.exe optimized for Xeon processors available Any answer could help me further. Regards, George Homorozeanu. I want to optimize our application for XEON processors because we have a terminal server and the application will run on that termina ...Show All

• gajar Writing Files to a Single Folder

  My application is developed in vb.2003. It is a database application that stores file paths in the database and the actual file data into a file. Is there a limit on the number of files that can be stored to a single folder Thanks, The limitation is based upon available disk space just to add, as long as 1 file does not exceed more than 4GB on FAT32 partitions, but this is now unlikely since most computers with Windows 2000/XP/2003/Vista use NTFS ...Show All

• SankaraNarayanan Nagalingam Building a defragmentation tool with VB?

  Hello :) I want to train my VB and had this great idea for a small defragmentation tool with Visual Studio 2005. Only problem is, is there any "easy" way to defrag hard disks with VB code I wouldn't have a clue about where I should start looking.. (if it's possible at all) So if anyone would have any lead as to where I should start looking/learning, thank you very much! Greatly appreciated, Steven This depends on exactly what it is you're trying to get experience with. I've been playing on and off with a project to do just this, but instead of rewriting the defrag process, I invoked the WMI defrag class. The end result is an application that triggers a defrag analysis on all servers in my d ...Show All

• Vladimir_Kost How can I cycle through all the System.Drawing.Colors?

  I worked out the Console version to cycle through all 16 available colors: Sub Main() Dim x, y As Integer For x = 0 To 15 Console.BackgroundColor = CType(x, ConsoleColor) Console.Clear() For y = 0 To 15 Console.ForegroundColor = CType(y, ConsoleColor) Console.WriteLine("Background: {0}; Foreground: {1}", x, y) Next y Console.ReadLine() Next x Console.ResetColor() Console.Clear() Console.WriteLine() End Sub I also worked out a program that cycles through 4 colors in a Windows form: Private Sub btnCycle_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCycle.Click Static x As Integer x = x + 1 If x = 5 Then x ...Show All

• Rudy Hentzen Clickevents for a dynamically built menu

  Hi, I'm making a custom browser with the webbrowser form and I've gotten stuck building the favorites menu. The way I have the code set up is that it reads all the favorites files and subdirectories in the user's default Favorites directory (Documents and Settings/$user/Favorites) and builds a dropmenu to the 'Favorites' menu button by adding the files one at a time as menu buttons. Subdirectories are also added, with dropdown lists of the files they contain. It's very similar functionally to the Internet Explorer favorites menu. Anyway, I have implemented clickevents for favorites menu using the DropDownItemClicked event, but this only goes down one level. I can't figure out any way to add event handlers to the buttons that dropdown from ...Show All

• bk13 Webbrowser control (x reamaining items) status bar implementation

  I am in the process of developing an application that uses a webbrowser control to display google maps. when I load the maps under IE6 I notice that the status bar displays something like "(x Remaining Items) Downloading Picture http://...." x is the number of items being loaded and decrements to 0. I am wondering if there is a way to display this same kind of status with my webbrowser control. i currently have a status bar attached to the main windows form that uses the standard code shown below. the current status bar only shows status until the main page is loaded. If someone could get me started in the right direction or provide a code snippet i would appreciate it. Thanks Jim Groleau Private Sub WebBrowser1_Navi ...Show All

• DavidAragornHouse Mircosoft office document imagaing file locking Visual Basic 2005

  Hi all, please can someone have a look at my code and tell me why i keep getting file locking issues when using a simple sql statement. Background info: My program splits a mulitpage tiff file (batch of purchase orders from Sage MMS) into separate files by doing OCR and using the MODI functions. My code has three main loops. 1st loop goes through each of the pages and splits the tiff into separate tiff files based on order number and stores them in a directory. for each order i also create an array of information by doing OCR from the tiff ie. order number, customer etc etc. 2nd loop goes through the array. for each order number in the array checks to see if there is another tiff file existing in another directory. This could be ...Show All

• Daniel Shevchenko How to use DLLs or APIs after you reference them?

• Manuel5 Multiple projects in one solution

  I haven't been able to figure out how to place several separate projects into one solution.  I create a lot of small demo projects that are related to a topic and have been opening them one by one in separate solution files.  Someone suggested I combine them into one solution but I don't know how to do it.  There is no option in the menu bar for adding a new project.  How can I place (or add)  my finished projects into a single solution   Also, I would need to be able to click on each one separately in the Solutions window and start it up independently of the others.   I did set the startup project to begin with the renamed Module2 instead of Module1, but it still only starts the first project. ...Show All
