View 13 RepliesI came across this great article on creating a custom datagridview column which creates a graph-like effect in the cells of a custom datagridview column:[URL]..Does anyone know how you would edit this to format the number in the cell as a percentage? And does anyone know how you would set this up to take 0 values which do not create any graph effects at all.I have been trying to do this but keep getting errors.

I have tried using every format of image I can produce, including (but not limited to) ICO, PNG, GIF, BMP, JPG etc... But every time, the app debugger clouts me round the head in defiance.. Windows Vista CAN do it.. and as in the image above.. StarDock figured it out..

View 2 RepliesI have made a custom control and the only change to the interface is that its a different color. Whenever the user moves their mouse over the control some white text fades in in the middle of the user control. Then after a few seconds the text fades out. The text is actually the location of the cursor but I have that figured out.

I found this question on StackOverflow. Basically, the user wanted to draw custom buttons on the titlebar. I tried the code and realised it works in vista/7 only when Aero is disabled. My question is, is there any way to draw custom buttons on the titlebar while aero is enabled? Any way of reading information from the current theme so I can style my buttons to match the already existing ones.
Here is a screenshot from my computer demonstrating the above concept. I got the additional titlebar buttons after installing DisplayFusion. And I know DisplayFusion is a .NET program because it opens in .NET Reflector. The down side is that the program is obfuscated. Not like I wanted to decompile the program or anything; I just want to add a button to my titlebar to do something else (like minimise to the system tray for instance).
Below is the screenshot, proving the program is a .NET app.
I have created a custom ToolStripProgressBar. It is basically a class inherited from ToolStripStatusLabel, and i paint the 'progress' bar myself (just a simple rectangle). I have tried creating a custom ToolStripProgressBar using different methods including inheriting from both ProgressBar, ToolStripProgressBar and ToolStripControlHost. I always ran into difficulties doing in this way. Inheriting from ToolStripStatusLabel works well, but with one issue...
In order to have the progress bar update in the statusbar, i have to call StatusStrip.Refresh. Trouble is, adds a huge overhead to the drawing of the progress bar graphics. Simply calling the invalidate method of my ToolStripStatusLabel does not seem to render anything to the screen. how to have my graphics draw without calling the refresh method?
I have a DataGridview. The user has to pick an option in the datagridview. I am contemplating either putting a context menu in the DGV. I am assuming that I will fire my context menu on the Cell Enter event. However prior to that I need to draw the users attention to the column of interest.
I know I can hide all other columns but his is not userful as they need to be visible. I am also assuming that I can highlight the column in the form load event. Or I could use some sort of Call Out box in the form load event that draws the user to the column. Can you create a call out box from a context menu?

I'm saving a bitmap as a jpeg using: savedImage.Save(fileName, System.Drawing.Imaging.ImageFormat.Jpeg) which is resulting in a JPEG with a 96dpi x 96dpi resolution and a 24-bit color depth. Is there a way in VB .NET 1.1 to change this to say a 72 x 72 dpi resolution and a 16-bit color depth?

View 2 Repliesi'm working on a project right now and I need to create a graphic library.The game I'm experimenting with is an RPG; this project is expected to contain many big graphic files to use and I would prefer not to load everything into memory at once, like I've done before with other smaller projects.So, does anyone have experience with libraries such as this one? Here's what I've came up with:
Have graphic library files and paths in an XML file Each entry in the XML file would be designated "PERMANENT" or "TEMPORARY", with perm. being that once loaded it stays in memory and won't be cleared (like menu-graphics)The library that the XML file loads into would have a CLEAR command, that clears out all non-PERMANENT graphics I have experience throwing everything into memory at startup, and with running the program running with the assumption that all necessary graphics are currently in memory.
I'm in need of a custom control that will allow me to do something like the attached image. It's basically a TreeView with the exception of having a row of PictureBoxes for each child node. I'd be happy with a ListView that could do this even. I tried it briefly with a DataGridView with ImageColumns but the "look" wasn't quite what I was after. I'd like the "Parent Node" text to be situated above the row of images and just can't seem to find a control that will allow this.

I'm trying to create a custom DataGridViewColumn and DataGridViewCell, and have found this article to be a great resource. I'm done creating the DataGridViewColumn class and the DataGridViewCell class, however, when I try to edit the type of the column, my new custom classes don't show up as one of the options. My DataGridViewScheduleColumn inherits DataGridViewColumn, so I'm not too sure what I'm doing wrong. Is there anything else I need to do to expose these classes to the IDE?[code]...

I believe that my questions are all going to revolve around the internal workings of DataGridView.While this is specifically written in VB.Net, it is definitely a general Visual Studio object question generically related to anyone working with .Net.I've been trying to find a forum where I can get some interaction and help to move forward.Microsoft's websites seem to be all questions and no answers.
I'm using VB.Net under Visual Studio 2005 SP2.I need to have a DataColumn that is dynamically visible based on other data in the same DataRow.After a lot of unsuccessful testing with various methods of accomplishing this, I came across the concept of Custom Cells/Columns.I started with several slightly varying examples and everything seemed to be falling into place. I tried to research each property and attribute as I incrementally learned a lot about the internal workings of Windows controls in general and DataGridView in particular.
The confusing symptom is that as I scroll down through the grid, the painting of the custom cells is at best unreliable.I created a minimum test case to eliminate as many variables as possible and I combined all of the source into one Form1.vb as follows:

I support a .Net 2.0 Windows application that has a custom listview control to allow for greater flexibility. I am not allowed to bring this to a newer version of the gramework until next year. We are moving from XP to Windows 7, and we have identified an issue with how the column sort image (up/down arrow) is drawn to the listview. Currently in XP, the image is drawn to the right of the column's text. However, in Windows 7, I am getting Access Violation Exceptions. Now, I know that the error is with the improper handling of memory using the unmanaged code as shown below. I am looking for a method to mimic what we have below in a safe manner using managed code.
