I am converting an old Vb6 solution to .net 2.0 in vs2010. I've been working in C# for about 3 years now and .net for 5. I don't recall having this problem in C#, but if I want initialize a readonly collection of DerivedControlFoo Is there a clean way to do it besides creating a sub to do it all off somewhere else? I'd love to be able to do it at the class level at the declaration for readability and simplicity.

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?
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 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.
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

View 2 RepliesIm currently developing a custom logging component, that we will deploy with all our applications, windows services, webapps, windows apps etc. I have a few questions of various nature. The component is a single signed dll file:
1) Which is the "safest" way to get the current directory? For example, in the config file, in the config section I have a property "logpath". The application will read this and write a log file depending in what they write:
c:myapplog (it will write a log here, create whatever folders it need) /Log (directly under the installed app directory, like c:program filesmyappLog) Log (same as above) I need something that work with both windows and web apps, for webapps it will log under the virtual directory of the aspnet app.

I have a UserControl with a Panel (Panel1). The UserControl has a property Items (type ControlCollection) that returns the Controls collection of Panel1.Via a custom CollectionEditor, I tell the designer that it should add my custom controls called Item (inheriting Control). For the sake of example, the Item control is just a control with a random background color:[code]The custom CollectionEditor creates new Item controls using the DesignerHost service (and its CreateComponent method), so that they appear as actual components in Panel1, selectable during design-time just like any other control.It might be a little hard to see (because the colored Items are docked to the top), but I have selected the red item, which can also be seen from the Properties list.
As you can see in the code, I attach a Click event handler to each item as it is added to Panel1. When clicked, a MessageBox shows the color of the item. Obviously this is just for the sake of this example, but the point is that I need to be able to click an item and something then needs to happen.This works fine during run-time. I can click each item, and the MessageBox shows.The problem is that it does not work (quite obviously) during design-time. When I click it during design-time, it is simply selected (as any other control) and of course does not register any Click (nor MouseClick) events.But, I need the Click event to fire even when in design-time! Clicking an item corresponds to selecting it, and when selected (even in design-time), some other panel (not shown in this example) should be brought to the front so it gets visible. Now, I have created lots of things very similar to this (clicking an item during design-time), but there has always been one major difference: those items were not actual controls on the form. Instead, they were drawn manually on to their parent (and they only looked like separate controls). Obviously there was no design-time support for those 'items' (as they weren't controls), but I could handle clicking them quite easily: by handling the MouseClick event of the parent, I can check the location and see if it falls within an item. If so, that item was 'clicked' (artificially).This time, the items are actual controls, and this method does not work (the parent does not receive a MouseClick event either).So, does anyone know of any way to do this? The only way I can think of right now (although I have no idea how to implement it) is to somehow 'listen' to changes in the designer selection.
I am running Microsoft Visual Studio 2008 Professional on a Windows 7 system.While working on a visual basic exercise in chapter 4 of the Microsoft Visual Basic 2008 Step by Step book on the MyMenu program I added a Toolstrip to my form and then I was trying to perform the add OpenFileDialog and ColorDialog controls to the component tray as described at the bottom of page 111 under Using Dialog Box Controls. I could never get the controls to appear in the component tray as instructed in the book.
I added a toolstrip to the form. According to my instructions I should be able to click on the Open file icon on the toolstrip to select it and then click anywhere else on the form. When I do that, the OpenFileDialog should appear on the component tray where I can then select it to enter code. This however does not happen.The only way I was able to get them to appear in the component tray was by opening the Menu program supplied on the DVD under chapter 4, selecting both of the above controls on the component tray, right clicking and then press copy. I then closed the Menu program and opened the MyMenu program that I created and then I was able to paste the two object controls to the component tray.
I went back to the original Menu program to see if I was able to place any other controls on the component tray by following the instructions in the book but was not able to. I also tried the same thing with MyMenu and it also still would not work.I have been unable to find anything that might explain why the component tray does not work as explained. Perhaps there is some setting somewhere that needs changed, but all searches have been unsuccessful.
PS. I have entered this on one of the other MicroSoft forums and although it has gotten multiple views I have not yet received any feedback.I also get the following error: Cannot add component of type 'ToolStripButton' to container of type 'form'.
I think (?) this is about object design, and perhaps about structural and/or creational patterns. But a bit hard to say when I only know a couple of patterns yet.[code]But... what if we INSTEAD want each Product instance only to (in some way) refer to one instance of a specific list of Components. So we wan't to save the products list to one file, and the components list to another file. Then would I build the objects the same way, or different? So let's then say we have now Class B as below. [code]
1. Will not need to update each component variable of the products list when the components list changes.
2. If the Product object shall be shown in a DataGridView, for editing properties, it seems easier to implement the selection of the component property.
Is this wrong approach? Is it suitable in some cases, and if so, when? Are there other solutions I perhaps am not aware of that would be appropriate? Is this about structural design patterns? and if so, can the alternatives above be catagorized to some pattern type? I don't really know exactly what I'm looking for.. But I think probably I'm looking to understand whether the object design will be determined by the way the objects are saved.. And if i shall save the objects by serializing to file, vs saving to a database, would I create the business objects differently?
