View 3 RepliesI'm trying to build a list that will be used as the in clause of a select statement. The requirement is to have the user enter a comma separated list of descriptions. Each description can contain spaces so I can't remove the spaces before splitting by comma to add the single quotes around each description. I want to remove all white space after a single quote since no description will start with a space. What's the best way to do this in VB.NET? Regular expression or a string function? Here's what I have so far.

View 3 RepliesThat mostly says it, I don't know much more to add. (-: The background is some random red after the execution of a sub routine. I then would like to have the backcolor dissolve from what ever value of red is present to a full white in about 1 second without showing other colors.(Unless it looks really neat...) Red could be anywhere from RGB(0,?,?) to RGB(255,?,?) when it starts to dissolve. Obviously the closer to 255 would make a smaller amount to change. However, I could be just as happy to see it go from RGB(150, to RGB(255, ?, ?) to get it started. The foreground is black numbers.

It works, just that there is any "white flash" when the appearance of the form .... I also tried on another computer (both powerful processor and graphics) ... It 'can be improved?
1. When I insert an icon in my VB.NET form, for example: a small shield icon, a white box appears around it and it's very annoying and ugly! I want to disappear the white box at the back of my .ico image.
2. This white backgroud not only appears on .ico files, but also on normal image files like .png, .jpg, .bmp.
I'm trying to display a white square in the upper part of a form but I have not the slightest idea how.
View 1 RepliesI've been working on some custom graphics controls, and I found this weird problem with windows 7 rendering my button controls. I've used Photoshop to delete the pixels in the background all around the button image I'm using, then saved it as a GIF, and imported it into VS to use as the background image of my button. When windows XP renders it, it is fine, but when windows 7 renders it, all 4 corners have an odd white border around them.
