• Visual Basic Access an application in server by multi-users

  I am a new VB.Net developer. I created a standalone desktop window-based application to query SQL server database and print them in crystal report. It is running well on desktop. My problem now is I want to put it on server of my company so that other users can easily access it without installing it on each PC. So I installed it on server and share the folder. On desktop, I allocated the shared folder of server and run it. But an error came saying: An unhandled exception of type "System.Security.SecruityException" occurred in ***.exe. I don't have any idea on how to deal with it. I appreciate if anyone can give m ...Show All

• .NET Development Cant view .asp pages in VS2005 local development server

  I have site that is mized .ASP and .NEt. I am developing with VS2005 local web server. ANy attempt to view an ASP page gives: ' This type of page is not served'. I can work around this on my remote server in IIS settings-- how do I do this on the local server OK, this is how you do it In VS2005 go file/new website choose HTTP (instead of File) for location Then supply a URL (e.g. http://localhost/MyWeb ) This will create the virtual directory on you machine When you then click view in browser it will launch IIS not the development server so you should be able to work on asp or aspx ...Show All

• Smart Device Development KeyDown-Event when I'am in gameloop

  Hi, I write a little Game for my pocket-pc. When the program runs into the gameloop how I can handle some key events Will they fire although Yup, you can handle KeyDown event. A PPC app has autogenerated code for key handling as follows private void Form1_KeyDown( object sender, KeyEventArgs e) { if ((e.KeyCode == System.Windows.Forms. Keys .Up)) { // Up } if ((e.KeyCode == System.Windows.Forms. Keys .Down)) { // Down } if ((e.KeyCode == System.Windows.Forms. Keys .Left)) { // Left } if ((e.KeyCode == System.Windows.Forms. Keys .Right)) ...Show All

• Windows Forms Differences between 1.1 and 2.0 : events triggered

  Hi there, I've just migrated our application to version 2.0 of the .NET framework, and I have an issue with the way events are handled.  Seemingly, they are handled differently between v1.1 and v2.0, though I've been unable to find any mention of this difference in the documentation. The issue is to do with events triggering before a dialog is made visible.  Specifically, I'm creating a form, and then before showing it I'm optionally choosing a tab other than tab zero as the active tab.  I achieve this simply by setting the SelectedIndex property of the tab control to be non-zero. Attached to the tab control I have an event ha ...Show All

• Visual Basic Delegates and KeyUp

  I am dynamically adding inkedits(rich textboxes for all intents and purposes) to a form and i want to capture the F2 key when the focus is on one of them and that key is hit... I wanted to do addhandler inkedits.keypress but that event only works for ascii keys. If i try inkedits.keyup the compiler is expecting a delegate object.. the examples i can find through searching the web dont really help me with the syntax.. i know i need to declare a delegate but i dont see how i can get it so i can create the code to handle the F2 event and create the instance of that delegate... Thanks for any help you can give. Confusedly, D ...Show All

• .NET Development CLR and Native code

  Hi all, I'm very confused of what is the role of the CLR after the MSIL is converted to the native code Does the CLR pops out each machine instruction and executes them Thanks, Suresh. I often read that CLR allocates memory,does garbage collection,resolve assemblies etc., I beleive these services are associated with the code at runtime (native code) Can you please explain more in detail... Thanks, Suresh. ...Show All

• Windows Forms possible to use VS 2003 IDE "server explorer" behaviour?

  hiya, I really like the way that server explorer: 1) stays collapsed at the left hand side of the screen when it is not in use.  2) expands to cover a tiny area when the mouse hovers over it. I have a fairly busy winform where this functionality would come in very handy to hide/display my "search" control. If this is not possible,   ...Show All

• .NET Development Obtain a Stack dump ?

  I would like to know if it's possible to perform a full stack dump in .Net Since the VS debugger is basically capable to navigating through the stack granting a visual access to all managed variables of the stack, this must be possible somehow. Such feature would be really useful for various purposes including debugging (post-app crash forensics) but also performance tuning (post-run stack analysis), etc... Does anyone know how to perform a stack dump in .Net Thanks in advance, Joannes If you are using Windows 2003 Server this might help: http://www.interact-sw.co.uk/iangblog/2004/11/16/stackdump ...Show All

• Visual Basic Datagrid OnClick to display row's data on another form2

  Hi, I'm using a data adapter 'da1' to fill a dataset 'ds1' which is used to display data in a datagrid 'dg'.
