• Kevin Rodgers Form Size

  hi, In windows application using VB.net how to dynamically increase/decrease control size when form size is increased/decreased. Thanks in advance -- Naren That would depend upon what you actually wanted to achieve. As you asked a very simple question then the could be yes . Anchor will allow you to determine which controls are anchored to the form. It may be that you only want some to be anchored. Plus different controls will anchor to different sides of the form. ie. Controls at the top anchor to the top of the form and controls at the bottom may anchor to the bottom. You may also want to set a minimum size for the form. Take a look at the TableLayoutPanel class... ...Show All

• Vijay Bhaskr Reddy.Y Is string in start of other string?

  I need to know, how to find out if string 1 in in the start of string 2. Example: string1: test / string2:testing = returns true string1: test /string2: gettested = returns false Take a look at the string's startswith function. Or you could do a comparison using the substring method dim s as string = "test" dim t as string = "test string" if t.substring(0,4) = s then '//This will be true end if Of you could use the left$ method (But this is older Basic method) if left$(t,4) = s then '//This will be true end if ...Show All

• daveCsharp Stupid NotifyIcon problem

  This is really bothering me since it is one simple line of code. I am unable to show a balloon tip on either my Vista machine or my xp box. I have created a new program to simplify things. It has a form, one button and a notifyicon. On the click event, i have the following: notifyicon1 . ShowBalloonTip (3000, "Test" , "Is it working" , ToolTipIcon . Info ) I see the notifyicon fine, but I never get the balloon tip. Anyone have any suggestions This is driving me mad!!! I tried your code in the load event and the tooltip showed only 1 time. Adding the code to NotifyIcon1.MouseMove allowed it to repeat. The notifyIcon.Text which shows on hover event is a ...Show All

• Tom_Liu Calling a sub and NOT recieving focus to the sub caller

  Hello, and I am trying to write a program that hopefully in the future will sell (That's just background info, not the problem) so I'm not going to be super-duper-specific about the program. The program will do very basic authentication (simply retrieving a user list from the registry and comparing it to the user-supplied username) and will call a sub in another form when the user is authenticated. I've got the authentication to work, but is there a way to call a sub in another form and give the other form focus (ex. call Form1.MySub from Form2 and give Form1 focus until the user closes the form or another form - just an example) If someone could help, that would be great! Sure, on the first form you hav ...Show All

• Leon Mayne How to make a .NET component binary compatible with a VB6 component

  My organisation needs to convert a number of VB6 COM components to .NET (VB.NET 2005) but have several VB6 / Office clients which need to consume these components and which we do not want to recompile and redeploy. We thus need to maintain backward binary compatibility between the VB6 applications and the new .NET components. I found the following question asked back in 2001 (!!) but cant track down the answer anywhere. "Is it possible through the use of attributes to make a .NET component binary compatible with a VB6 component Has anyone done this " Clearly, this is exactly what we need to do, so, any suggestions - and sorry if this is a boring old question - I did search but couldn't find a clear answer.

• mohdtmn Convert byte array to bitmap and vice-versa

  Hi, How do I convert a byte array to a bitmap and vice-versa in VS2005 Thanks, Ivan well you could write the contents to disk and read from that if it helps or you could write the byte array to memorystream then use an Image object to read the data from stream A huge amount depends on the pixel format of the image. Create a bitmapdata object by using the LockBits method of the Bitmap Class. Use System.Runtime.InteropServices.Marshal.Copy to copy between array and the locked bitmap. Unlock the bits on the bitmap. From Image to byte array:   Me .Picture1 = New Bitmap( Me .Image)   Dim ptr As IntPtr   ' Lock the bitmap's bits, get ...Show All

• DeadlyEvilRyu Why does the Graphics Path shape not display correctly?

  Hi pals, Yesterday i posted a very long thread on my drawing a Graphics shape. Let me be brief here: First of all, The path is filled and drawn with the right and bottom sides clipped. I don't know how to get around this bug. How can I draw it correctly so that the it fills and draws a border nicely without any clipping. Note: I am using a graphics path object here, not a rectangle( where i could use the inflate method) Secondly, after drawing the shape and assigning as a region to a control, the result is so crappy: jagged pixeled lines. When i don't do any region assignment, the drawn lines are smooth and nice(even though the right-bottom clipping still occurs). Please I really need your help on this. I have dived into GDI ...Show All

• SulaimanA Custom radio button column in DataGridView

  I am working on adding a custom radio button column to a databound datagridview in a VB.Net app (Visual Studio 2005) and I'm a bit out of my depth.
