• Visual Basic Creating a program that can save in a specific file format.

  Hello, I was wondering how (and if) to create a program that will allow me to type some text, make some selections, and then save it. What I need to know is how to save the program then be able to re-open it properly. Thanks for any help. When you say "make it select the file format" I'm guessing that "it" refers to the Save and/or Open dialogs. Is that correct If the extension .TMS is the only extension you wish to support, then you set the DefaultExt property on the Dialog Control to "tms", and the filter property on the dialog to "File Type Description|*.tms" ...Show All

Very often if you don't parametrically sample the contents of an image and just move the sample into a container, there may be losses of image qualit ...Show All

• SQL Server cannot view

  Thought I edited a previous post but apparently not. The cannot view problem is with a png file inserted on a start page of a web site. Other Gif and Jpeg files are viewable with IE and Mozilla but not the png file. Sorry for the confusion as I am a new user to these boards and didn't get the post in place as I intended. We've placed some banner ads from sponsors on our web site and I cannot view them with IE. The ones that are there in either Gif or Jpeg are viewable but we have one in png and I cannot see it. This same banner is on another site in Germany and I cannot view that one either. I've also tried ...Show All
