what kind of components is this? specifically the tab control that acts like a chrome browser wherein you can add Tab and remove it at the same time, in addition adding new tab displayed the Main menu for whatever tasks the user wants...
Here is the screenshot of the tab control.[code...]
I have a context menu strip, and I need a way to add some kind of file to a folder in my documents. My program will get all the files in that folder then allow the user to pick one of the files. When a file is picked, the file changes the context menu strip completely. I can't figure out how to do this. I figured it could be done with a class library but I guess not. Any help would be great. And some extra info. I need to be able to externally code the file so that when a button in the context menu strip is pressed it does whatever the files tells it to do. How can these things be done?

I've created a component whose name I'd like to be able to change while editing in the component tray. I've added a Designer action for a name property, but now I'm stuck.
Looking at the property grid, I can see that the name property is parenthesised, indicating that it's not a regular property.

View 17 RepliesHow do you create your own custom component for vb.net 2008? I want it to simply output to a .dll, not a whole winforms app.
How can I control the component? For example, I want my component to not have a visible design view, I want it to stay below like the stopwatch component and the notifyicon component and such, it is not something to be designed. Then, how do I edit the possible properties a user can control, and make them effect the end result?
Im using the component in visual basic 2008 it is ExtCursors. I get it here. Its fine and working great, but I want to change the cursor everytime the users mouse was hover in a button. I want my preferred cursor not the cursor in vb 2008.
View 11 RepliesI have been asked to add some functionality to an application which will require Microsoft Word. The new work needs to allow the users to create .dot files and perform mail merge operations. I have gone down the road of using the dsoframer component in the past and would prefer to avoid it if possible.
Can anyone recommend a good third party component that will allow me to do this sort of thing?
I have noticed that the controls I have looked at seem to be viewer controls allowing read only operations which is not good enough for this task.
We generated a class from an XML file a while back. I think we used xsd.exe.
One of the main node collections in the XML file was rendered as:
<System.Xml.Serialization.XmlElementAttribute("PRODUCT")> _
Public Property PRODUCT() As PRODUCT()
Get
Return Me.pRODUCTField
[CODE]...
And sure, there's PRODUCT class defined later on, and it worked fine. Serialized and deserialized fine. Didn't need to worry about it or manipulate it. Only now we have to revisit and manipulate the data.
But what kind of collection (array?) is Public Property PRODUCT() As PRODUCT(), and how do we loop over it? And add to it? Basic question, I know. Probably got too comfortable with generics and now xsd has thrown something at me which isn't List(of T) I'm running scared.
I have just run into an issue of screen flicker that I haven't been able to solve. I have a panel with dozens of controls on it. Painted onto the panel, behind the controls, are a few colored rectangles.
Those rectangles flicker whenever the mouse is moved over any control, or off the panel. Basically, a paint event for the panel is raised whenever the mouse leaves the panel.
Therefore, I thought that if I only painted the rectangles when they needed to be painted, not every time the Paint event was raised, that I would be able to avoid the flicker. After all, there is no obvious reason why they would need to be re-painted just because the mouse moved over a control on the panel.
the paint event was still being raised, and the panel just wasn't painting the rectangles, so they weren't being drawn at all (but they sure didn't flicker). So, the flicker is being caused by the fact that the paint event clears the panel, which gets displayed in a cleared state for a fraction of a second, then the rectangles are drawn in.
Doublebuffering the form has no discernible impact, which may well be because the screen draws the absence of the rectangles on one frame, then draws the presence of the rectangles on the next frame. They both get shown in sequence, so the rectangles appear to flicker badly.
One obvious alternative is to not even draw the rectangles, which works great, and they are only useful visual guides, not essential components. Still, that doesn't seem like a good solution.
So what I am looking for is a way to supress the display of the undrawn image before showing the finished image.

My app is a classic vb6 app. I have distilled my problem down to fact that an activeX control can't be registered on Win 2008 64 Bit using Regsvr32 but can be registered on Win 2008 32 bit and on Windows 7, Vista, XP/Pro, Win 2000 etc. The classic vb6 app works well on every Microsoft platform except Win 2008 64 Bit. Some Win 2008 64 Bit systems seem to work and we're not sure why, but many don't. The application fails with 429 error when run and when you try to manually register the activex component using regsvr32, the registration process hangs with this result[code]...
View 2 Replieshow to use a notifyItem component with a contextMenu. At the moment I have an icon which starts when one of my mainform loads up, it has an option to exit and it loads a form on click which is mainly what I need. But because I have more than just one form I need to know is there a way of having one notifyItem for all of the forms (for the whole application) or would I have to create a duplicates for other form. Because it closes when he form closes and the other form doesn't have a notifyItem.
Another thing I would like to know is how to get the form dissapear when closed, I mean I could just do visible = false but I want it shrink towards my notifyIcon like all the other applications do
