tnsgod831 Picturebox format conversion?
I'm running into a minor snag. I load a bitmap into the clipboard using the Ctrl+C command. The program I wrote, then copies the clipboard into a Bitmap object. Next the program assigns this as the Image of a Picturebox object. So far so good... This is where the problem pops up. The Image displayed in the picture box is a dithered image. A nice solid brown patch becomes a dithered patch of color. It shouldn't be system display settings, since the original image displays properly. It isn't the copy operation, since I can set the clipboard object to the bitmap I just loaded, paste it into a graphics program, and the dithering is not there. It appears to be a function of the picturebox assignment. Sample code: Private ...Show All

BobH Bound Datagrid - Floating DatagridTextBoxColumn
I am using VB.Net 2003, and I have a datagrid that needed a checkbox column, which in turn seemed to force me to make the rest of the columns to be DataGridTextBoxColumns. The data is just for display - no changing - but if the user clicks on one of the textbox cells, then clicks off the grid, and repopulates the datagrid, the cell that they clicked on is floating around in the datagrid painting area, no longer responding to the scrolling events. The only way that I've found to get rid of it, is to close the app, and restart. Any ideas ...Show All

Tiarnan To deploy from Release folder or Debug folder?
Hello, In visual studio 2005, I have the option to set the configuration manager to output my files to a debug folder or a release folder. Right now by default, it is set to the debug folder. To deploy my vb.net application, would I use the files in my debug folder, or change my program to dump files in the release folder and then use tthe files that reside in the release folder I have used the click once deployment option but finding my application taking way to long to start up after a cold boot, where as if I use the files from my debug or release folder, it starts up fine. Any advice, or clarification on debug and release folders is greatly appreciated. Thanks. Then to deploy the applicat ...Show All
jeffers Visual Basic Express application stops before showing form on another computer
I have now tried 3 separate applications, one being just a simple form with no underlying code at all. All three applications will run fine on my Dell desktop (XP) and Dell laptop (2000) but will not run on my Toshiba laptop (XP). I do the development on my desktop so I cannot run debug on the Toshiba laptop. When I run the applications on the Toshiba, the process explorer shows it starting and immediately stopping. Placing a few log statements in the code, I noticed that the application is stopping when the form is trying to display. Load form is working fine but show form does not seem to be. This must be a configuration issue with the Toshiba as it is the only computer that does not work. However, I have done all MS ...Show All

mccpres populating an Access database using visual basic 2005
I am trying to create a new employee application that gets input from a user in text boxes and then take that information and populate a database in Access that will later be pulled to the Track IT! database on SQLserver2005. How do i do it Thank you. no worries, glad I could help - it's all about asking questions and learning, even the answerer learns from other responses! Good Answer! there are a few ways of doing this but the easiest way probably would be to use a datagridview and dataAdapters. the datagridview is a control which allows you to databind values to it, and you can view/delete/edit/add records to the control (similar type of layout as when you view a Table in MS Acc ...Show All

Shawn Wildermuth - MVP &#40;C&#35;&#41; 86 bit and 64 bit Winows operating system
Hi Im developing on windows XP 86 bit. But the program will be runing on a 64 bit operating system. Do we have to compile it in a certain way that it will work on a 64 bit If i compile it on my machine will it work on a 64 bit Thanks in advance :) If you are using VB 2005 - and you are developing on a 64 bit machine (the machine which has VB installed on) then you can select which Processor you want to target - Remember that you can create a 32 bit application which will run on either the intel or amd 64 processors OR you may specifically target the processor. Most 32 bit applications .NET should work just fine on a 64 bit OS. Its just not going to leverage any of the benefits of the 64 bit processor. This is why the d ...Show All
Attila Fogel Regex match from hell
For all of the amount of time I've been wrestling with this, I could have coded an (inelegant) solution from scratch, but it's bugging me to distraction and I won't sleep until I figure it out. I'm doing a conversion of some data pulled from a mainframe into a text file, turning it into an XML document. The rules are: Each line consists of a number of elements, separated by commas. Each element can either be a double-quote surrounded string, or nothing. The last element has no following comma. So a line of data could look like this: "Value1","Value2",,,"Value3",,"Value4","Value5" I thought this would be easily handled with a regular expression: (".*& ...Show All
