Can anyone tell me, is there any advantage to using aximp/tlbimp for creating Interop DLLs over letting VS.NET do its stuff (by customising the toolbox to add a COM object)?
Is aximp mainly for those not using VS? Is VS using aximp to "do its stuff"?
Just wondering... what is the relationship, if any?

aximp.exe is a simple cmdline that in the end just calls the System.Windows.Forms.Design.Aximporter.GenerateFromFile(string typelibfilename) method from the System.Design.dll namespace.
There is strictly no point in using this cmdline instead of letting VS.NET do it. After all, that's the same reason why you choose to compile C# code with the IDE instead of the cmdline.

Thanks SR.
This is exactly what I expected but I saw aximp mentioned in an article or two and it started to niggle at me. Figured someone here would know and I'd be able to forget all about it  .

Actually, there's a couple reasons: overriding the default namespace, generating source code, and providing a key pair (although you can do the latter via project options in VS.NET, but it's often forgotten). It's *rare* one has to do this, but I did have to for a couple ActiveX controls that were poorly written in the first place (but we needed them...drats).

I'm sure that others have noticed this behaviour, but I have searched all over for a resolution to no avail, so I'll post it here.
When using windows XP visual styles (via manifest file) with a TabControl there are numerous display issues.
The most well-known is the fact that the TabPage background is not correctly painted with the WinXP gradient - this I actually don't care about as my tab pages are filled with either listviews or picture boxes, so the background is irrelevant. This issue has of course been addressed here on the CP already.
The major problem for me is that of you select anything other than a top alignment for your tabpages in conjunction with using winXP visual styles the tabs themselves are drawn totally messed up, along with the text on tabs mysteriously dissapearing.
The app I am developing is heavily reliant on tabcontrols, using a mixture of regular (align=top) controls, with a few left-aligned tabcontrols. Resorting the top-aligned controls throughout will simply waste far too much desktop space, so is not an option.
So here's where I'm at - it's either ditch WinXP visuals, or draw the tabs myself. I really don't want to have to resort to losing the XP look, so drawing the tabs myself is the way I'd like to go. The problem with this is that I simply cannot find an overridable method that allows me to paint the actual tabs (painting the tabpages is no problem), and at this stage the thought of writing my own TabControl from scratch is almost enough to make me turn to the drink.
Can anyone help?

No dont drink! How about using the MagicLibrary's Dockin Controls. I have found the are almost a substitute for MDI forms and the TabControl.

Ah, come on. Drinking in moderation never hurt anyone and has even helped to churn out some interesting code form time to time. 
Just wanted to vouch for Magic. We use them a lot at work and I and my colleagues have even suggested many improvements to the author. There's not very good documentation, but after "suggesting" that every third-party control libraries "require" it and throwing the NDoc project I help with at him and offering to help with the documentation process, docs will soon be on the way.
Other than that, you can't really find a better *free* library - or even a commercial library for that matter.

I agree, was a bit difficult to gather at first, but you tend to get the hang of it.

I agree again  COmmercial quality for free I just wish I was a commercial programmer.

About 2 hours before I posted the orginal message here I downloaded v1.71 of Magic - the problem is I really do need to have some left-aligned tabs (vertical) as well as standard tabs. The thing with the base library control is, you can specify OwnerDrawFixed, but I just can't find ouy how to actually paint the tabs..
|

Magic will do vertical tabs (note, not "left-aligned" - that has to do with text alignment). He even has an example of it in his sample application.
As far as owner drawing, you basically have to take the PaintEventArgs.Graphics property and go at it. Take a look at the System.Windows.Forms.ControlPaint class. It has a lot of helpful functions to draw things like borders and glyphs. It can simplify your UI and keep it consistent with Windows.

Unfortunaltely, MagicTab has a problem with focus on complicated controls. I use MagicTab, control inherited from DataGrid on it, and some inherited controls on this inherited DataGrid. Keyboard works ok, but after mouse click focus "goes" from my controls to DataGrid. May be it's my mistake, but these objects on Microsoft Tab works ok ...

Controls placed on MagicTab (instead of DataGrid) works ok.
Simplified controls (with no sub-controls on them) works ok.

if you could only...code one language for the rest of your natural life...what would the language be ? ..as for me... i think C#....cause its the only one i really know lol..
|

C# is nice, my choice at the moment as well, but as I'm starting university this year, i'll be moving to C/C++. AT least I feel C# gave a good background on the working of these languages.

Definitely C++. C# is nice and all, but it's not practical in every application. For modern systems, C++ is like the glue that ties everything together and is the groundwork from which almost everything was written, from compilers to back-end functions to COM.

The thing is, you have to use different languages within different contexts.
You probably won't ever do device driver dev. in C# or client-side scripting in C++.

I've seen this in the Managed DirectX samples:
MouseState mouseStateData = new MouseState();
// Get the current state of the mouse device.
mouseStateData = applicationDevice.CurrentMouseState;
Could you explain me why there is a need to instanciate the MouseState class? Doesn't the property return an object? Isn't the expression "new MouseState()" redundant?
|
|
|
|

You are most likely correct, and I have seen many such examples in various .Net docs. I have always been able to remove the unnecessary instantiation, as one would expect. Do not assume example code writers have their code carefully checked. They don't have to produce good code, and rarely do they ever receive feedback.
Cheers

I used the DataTable.Rows.Find() to get a DataRow. Now how do I obtain that row's table index?
I dont see any DataRow.Index property or DataTable.Rows.IndexOf(PrimaryKey) method.

Hey every one, does any one know what the hell is wrong with this code =/
i am trying add a Node(file to the treeNode)works fine except
that
i am doing a check to see that the user wont add a same file 2wice but its
not returning a right value
its the second if statment
can you tell me whats wrong with my code thx
//Add Nodes to Tree
<br />
private void Add_Click(object sender, System.EventArgs e) {<br />
<br />
TreeNode currentNode;<br />
<br />
<br />
OpenFileDialog ofd = new OpenFileDialog();<br />
<br />
ofd.Filter="lib files (*.dll)|*.dll|Executable files(*.exe)|*.exe";<br />
<br />
<br />
if(ofd.ShowDialog()==DialogResult.OK){<br />
<br />
currentNode = new TreeNode(Path.GetFullPath(ofd.FileName));<br />
<br />
<br />
if(treeView1.Nodes.Contains(currentNode)==false){<br />
<br />
treeView1.Nodes.Add(currentNode);<br />
<br />
numberFiles = treeView1.Nodes.Count;<br />
<br />
Counter.Text=numberFiles.ToString();<br />
<br />
}<br />
<br />
else{<br />
<br />
MessageBox.Show("File AlreadyBeen selected","Warnning");<br />
<br />
currentNode=null;<br />
<br />
}<br />
<br />
}<br />
<br />
}<br />
Thanks in Advance

You are comparing 2 instances of TreeNode objects, which will allways return not equal, unless you comparing it from a reference (but thats not what you should be doing). The TreeNode object has exactly what you are looking for in the Tag property. Here you can add some string or number and use that to check for equality, not the actual TreeNode objects.

currentNode = new TreeNode(Path.GetFullPath(ofd.FileName));
currentNode.Tag = Path.GetFullPath(ofd.FileName);
if(CheckNode(currentNode)){
Then
private bool CheckNode(TreeNode node)
{
string test = (string) node.Tag;
foreach (TreeNode n in treeView1.Nodes)
if (n.Tag == node.Tag)
return false;
return true;
}
