  Hi, I am busy making a world clock program showing 5 clocks from around the world. I have a coupel of problems: 1. How do I substract hours from the system time Or is there a way to take GMT and substract/add to that time 2.

• Visual C# Novice vb 2500 tcpListener accepting connections JUST FROM ONE ip address

  Hi guys! I've been using TcpListener and TcpClient classes (I read examples from on line help of Visual Studio 2005). I succeeded in making a tcp server that works quite well. Now I want that this server could accept connections from just one and only IP address (that I choose). Does anybody know how to make it I think it's a simple trick but I'm not able...

• Jim Shipley WebBrowser Refreshing Problem

  I've got a WebBrowser control in my current program that, every minute and a half, loads a web page and parses some string information out of it. The problem is, after running for a while, it stops reloading the page; everytime it 'loads' the page, it loads the exact same contact the page had the last time it was loaded, although the actual page content has changed. Viewing the page in IE outside the program, I can see visually that the site really has changed; but the program continues only to see an older version of the page. Why is this happening, and how can it be fixed Note: the problem persists when I log on/off the computer, and when I restart the computer entirely. It doesn't happen for all pages being dealt with in thi ...Show All

• GoDaddy please any one help me

  i want any code to compute the factorial of high numbers like 1000000 in aspeed way & didnt cause the break down of memory any bode cane help me mn_fci@hotmail.com mn_fci@yahoo.com How accurate do you want the final number to be If you're looking at a handful of significant digits, you can lower some accuracy and increase some speed. I am afraid that what you are trying to compute will require exponetial time due to the memory access it requires. So, there is no "fast" way to compute this.

• Hani Felemban Why do some keyboard shortcuts not work.

  I can only get some shortcuts to work. For instance, I cannot assign a shortcut without also assigning it ctrl, shift or alt. On the same note, only ctrl and alt work. When using shift it gives an error. How do I get around this. I also want to use shortcuts like: S instead of say Ctrl+S. Also, how do I assign the Esc key to a shortcut. Thank you. Troy L. Operator '=' is not defined for types 'Char' and 'System.Windows.Forms.Keys'. Also, It will detect the keypress if I hold shift while pressing 's'. Maybe it is looking for Upper Chars Troy L I believe you can change some and assign some to the IDE by going into tools > options > environment > Keyboard. whats stopping you from using the key down event and ...Show All

• Dietz Open file

  Hiiiii, How i can open file (word,excel etc) using vb.net (web base).. But not using response.redirect(namefile)... Please help me.. Thanks Jebat He is trying to open an excel file locally using the web application in VB. That's my take on it. The easiest way would be to save the excel as a CSV (Comma Delimited File) and parse it line by line. That way you can open it with file.opentext(filename). If your asking how to open word/excel files from a web page - then using process.start wont work as it will open the file on the server and not on the client machine which is what I assume you are trying to achieve. Your probably better asking this question o ...Show All

  I'm taking a VB class for financial analysts, and we're tasked with constructing a progrm we can use on the job.

• MaryOS How to create a docking/undocking toolstrip in vb 2005 ?

  Hi can anyone help me in creating a dockable/undockable toostrip in vb 2005 Shailendra Kumar Thanks i will try it and let you know about it. Thanks again Shailendra A toolstrip can be docked like every control, so it's just a matter of setting the .Dock property of the toolstrip to 'None' when undocking, some code to simulate grabbing the toolstrip and repositioning it, and some code to look out when the mouse is close to an edge of the form so it can suggest docking to it. Here's a working example, but you'll have to adapt it to your own needs. The ToolStrip seems a little quirky about mousemove events, so it may drop from your grasp occasionally. ...Show All

• dagjo In the registery?

  I have written a program that requires a password to be created when it is first run, this is then encrypted and stored on the computer C:/Test.txt . the next time the program is run you enter your password, which is encrypted and compared against the encrypted password on file, and if they match you can use the program. I don't think storing the encrypted password as C:/Test.txt is a good thing, so where is the best place to hide it away, and how is it done Any help, advice or interesting articles will be welcome. Thanks Spotty, Don't think I can do it this way as the password entered by the user is the Key and IV to encrypt the password, as I don't know what the user will enter then I can not enter it ...Show All
