kkarrancsu How do I copy bitmap data to a buffer?
I have an application that displays some images using PictureBox. There is a requirement to toggle between colour and monochrome or grey-scale versions of the image, so I've created a class derived from PictureBox that contains extra bitmaps that hold the various versions of the image, and then when the user switches between them, I just assign the relevant bitmap to the PictureBox. When the image is first loaded, the application generates the monochrome and grey-scale versions from the loaded colour version. This is where the problem lies. For each version of the image, I make a clone of the original, and then loop through X and Y, using GetPixel and SetPixel to change the colour based on a conversion formula. That also works ok, b ...Show All

DQM Graphics: smoothing problem
Hello, I would like to use the circular progress bar control that is shown on the Code Project site at this URL: http://www.codeproject.com/useritems/sql2005circularprogress.asp The control works well, but the inner circle is not smooth. This is especially evident when the control is enlarged. Any ideas how to make it smooth Thanks Tom Hi Mike, Thanks for taking time to reply to this question. I think I must be missing something. I tried to add the 5 lines at the end of the method CalculateSegments(). The e.Graphics.FillPie... would not compile there, so I put that line where the "e.Graphics.ExcludeClip(innerBackgroundRegion)" was and it compiled, but it did not create ...Show All
MarcoB Problem reusing VB6 control in VB .NET - created from Progid
I'm having some problems in trying to upgrade a VB6 application to VB .net 2005 - I hope someone can give me an idea where to look: The basic upgrade process worked fine, but I'm having trouble with some VB6 / .NET interoperability. The part of this application I'm having trouble with has to create ActiveX controls from their VB6 progids. The old VB6 code used to create these activeX controls dynamically from progids using "controls.add". In .NET, I have tried converting the "controls.add" code to the following, where progid refers to a vb6 user control. (Note that there are a load of these controls which all work perfectly well and I really dont want to have to upgrade them to .net!) When I run the code ...Show All
Blkbird textbox text not updated
I have a several subs where a textbox writes whats happening. The sub could look something this private sub DO_Something txtstatus.text="Now doing this" call Another_sub me.close End sub But the problem is that the textbox doesnt write the text im telling it to.

How can i get it to write the text in the textbox Well this is frustrating. The board chokes on my full post. Lets try a stripped down version. Try This: ...Show All
Jerod Moemeka Printing directly
I have in the past created a way to print by creating a file and using writeline methods create the content and then in the end send the file location to a print method that would print the file... but now, I want to print directly to the printer but after I create/format the output. However I am pretty sure the program will run over a network with not enough privileges to create a file, is there a workaround to creating the output and then sending it to the printer thanks, johnp There are several different approaches to setting up a print routine. 1. A one page printout where you want to absolutely position everthing yourself (Print "AAA" at X,Y position, print "BBB" at some other X,Y ...Show All

Nick W. FileSystemWatcher - Created events fires too early
I have been playing with a FileSystemWatcher, to start processing files as soon as one arrives in a folder. Specifically, I'm looking for a zip file, then unzip it. However, when I try to unzip a file as soon as I get the Created event, the file has often not finished being written, and therefore I get an error when I try to unzip it. This time period is very short, a tight loop without pauses trying to open it for write will return OK in 3 loops. Question ======= How do I get FileSystemWatcher to raise an event when a file has FINISHED being written, instead of START being written Thanks for the tips Jim 1. Agreed 2. I like the incremental idea. There's a parameter called intTimeOut ( ...Show All
fbecker How do I use Team Build/Team Explorer
The long and short of the whole problem is this: I can't find Team Build. I have Visual Studio 2005 Team Suite installed. Team System is all there. I need to be able to set up an automated build, involving several different build projects, need support for local builds, and I need to have logging done by Team Build (most importantly it must record any errors encountered during the build process down to the line of code). But I can't do any of that because I have been unable to find a way to open Team build, or access its functionality through Visual Studio 2005. Despite the fact that it shows up as an installed component in Add/Remove programs, has it's own directory full of installed components, and can detect already installed components ...Show All
Ariel Erlijman User Control problem
I have a UserControl which basically shows in a textbox the content of a row in a table relationally linked to another table in a database and also a combobox containing the contents of that second table. This mean that as you travel through the main table you can see what the linked text entries are and have a combobox when entering a new record. I started the table in VB.NET 2002 and upgraded it to VB2005 Express and have been using it successfully for some months.So, it has saved considerable code and added to my VB skills. However, having recently discovered the MaxDropDown size property for the combobox I wanted to add a line to the UserControl to fix the MaxDropDown size to be the size of the records in the table it accesses.

Hello everyone. I have a login form which has a username, password, and login type (i.e. user,admin) fields and I want to add the code in the LOGIN button.

Linda Shao Old code issues...
I use VB6 at school, and was quite used to doing the following: number = txtbox1.txt mumber = number+42 lbl1.caption = number Why does it not work with the new version, and hw can I fix it What I'm looking for is a way to get text (in this case numbers) from a textbox, manipulate it, and output it to a label. How can I do this Also., for later purposes, how do I directly output a textbox to label While we are talking best practices on checking your input, you would need to wrap your code in a try-catch block if the value entered in theTextBox was not a number. Otherwise, you will throw a FormatException at run time. Alternatively, with 2005, you can use TryParse as follows: dim theNumber as Integer If Integer.TryP ...Show All
