Hi there:
I strongly beleive there is a strange logical problem with the overall docking behavior of the dotnet controls. What a developer needs is that what control he docks first, gets docked first regardless of in what order the controls were added to the container. But dotnet IDE docks the controls in a specific order that somehow depends upon in what order the controls were added to the container. The worst is dotnet doesn't explains what is that specific order. Let me xplain the problem by an xample:
1) In any form, add a panel.
2) Create 2 label controls on the form called label1 and label2.
3) Drag label1 to the panel.
4) Drag label2 to the panel.
5) Set the Dock property of both to bottom.
6) Doesn't matter, in what order u perform the step 5, label2 will always be at the bottommost position.
Now repeat the same procedure as above, but change the following steps.
2) Create 2 label controls directly on the panel called label1 and label2.
6) Doesn't matter, in what order u perform the step 5, label1 will always be at the bottommost position.
SO u can clearly see that docking behavior is changed in both cases. In step6 of first one, label2 will always be docked at the bottommost position, while in 2nd case, label1 will always be docked at the bottommost position. Is this behavior justified and can developers rely on this type of uncertain behavior. Plz. comment on that.
The practical problem, i'm facing due to this uncertain and unjustified behavior is that:
1) I have made a custom container control, which has a label(acting as a caption). This label must always be docked to the topmost position in this control, so i have set Dock=Top for this label.
2) But due to dotnet docking behavior, when a user adds another control to this custom container and sets the dock property of that control to top, it gets docked at the topmost position and the caption label gets one level down, while it is not expected to change the position inside the control.
Is there another solution available, so that my label always stays at the topmost docking position.
There is anoher issue, at which i need ur comments, although i'm not sure whether its really an issue or not. The issue is based on the basic OOP principle of Composition. In original C++ or Java, when ur class(say ClassA is composed of two or more classes(assume its two classes named ClassP, ClassQ), then none of the classes ClassP or ClassQ is supposed to lose any of its functionality in any way when contained within ClassA. But in dotnet it happens. How?
1) Start a new Cutom Control Project.
2) To ur custom control add a label, that is supposed to act as a caption. Dock it to top.
3) Add a panel to ur custom control and Dock it to "Fill".
4) Build the project.
5) Add a new windows application project as the testing project to ur solution and to the form in that project,add an instance of ur custom control.
6) Run the project and u see the panel has lost its functionality as a container.Y??
In answer u may tell me that if i want my custom control to be a container, i should inherit it from ContainerControl Class. But no, the whole of the control is not supposed to be a container in my case, only the area that contains the panel, need to act as a container. So while talking about the basic Composition principles of OOP, the ClassP and ClassQ should not lose their functionality, but in dotnet panel loses its main functionality as a container.
If u feel these are the problems, plz. tell me how can i notify microsoft about that so that they corret these bugs in their next .net release.
PLZ. HELP ME OUT

I want to know how to write a xp style toolbar , Is there some Sorce Code?
|
|
|
|

Are you referring to Windows XP, or Office XP style toolbars? In any case you will need to obtain some third party package to accomplishw what you want, whether it be here in CP or available through purchase. You can always enable the XP themes using a manifest file, but this may not be what you want.
Some examples of good third party UI kits:

Also when i go to Source Control I see everything greyed out.

Has somebody tried the February Preview of the VS 2005 Express versions?
I know that MS is warning that they might cause trouble and I want to install and try it on my main machine, that's why I'm asking if you had troube installing and uninstalling it and are there any other troublesome issuies.
Thank you!

I've tried it, didn't cause any problems. In fact, at my home machine, I've got Visual Studio 2003, Visual Studio 2005 beta 1, and Visual C# Express February 2005 CTP all installed simultaneously, no problems.

Hi all,
I've a little problem using timer.
I used a timer with an intervall of 1 sec. and i do :
private void timer1_Tick(object sender, System.EventArgs e)
{
counttime++;
}
and i want to retrieve the counttime value at any time in an other function.
i do like that :
public void Func()
{
bool temp = false;
while(!temp)
{
if(counttime == 3)
{
MessageBox.Show("OK");
temp=true;
}
}
}
But the MessageBox is not shown.
Does anybody has an idea ? ( the timer is enabled of course)
Thx in advance

I tried your given code and the problem was that the main thread was blocked because of the while loop. One solution could be to put the while loop in a seperate thread.
after that the message box was shown
|
|
|
|
|
yes that was the problem
Thx a lot hooray.

what is the difference between storing my temp info in traditional files(text,binart)and XML files using c#?
i mean when do i need to store my info in XML files?

The primary advantages of XML are:
* human-readable and editable
* can be transformed into different formats using XSLT
* can be queried using XPath expressions
* well defined programmer APIs for editing existing data
* .NET supports serializing objects to XML (and vice versa)

The primary disadvantages of XML are:
- big files (because of verbosity)
- appending is slow
Just for record.  There are lots of articles on the web discussing topics where to use XML and where XML is not suitable for some reason.

Happy Friday! Gurus,
I am trying to use the logics from Intel OpenCV DLLs, which were originally compiled by MSVC++ 6. From C# or ASP.NET Apps, when I was trying to add reference to these DLLs (i.e. cv096.dll or cxcore096.dll), I got this error:
“A reference to ‘D:\Programs\OpenCV\bin\cv096.dll’ could not be added. This is not a valid assembly or COM component. Only assemblies with extension ‘dll’ and COM components can be referenced. Please make sure it is a valid assembly or COM component.”
Note: The source code of Intel OpenCV DLLs is open source. I can open this source code project in either MSVC++ 6 or VS.NET 2003.
Question: How can I use these DLLs in .NET environment, preferably in ASP.NET and C# projects?
Thanks with a million

And i dont mean how do i read/write to the registry, i mean where do i put keys and values?
this is so that when my app ouputs a file, the user doesn't need to do file-open with, and its already done.

Opoen regedit and start poking around in HKEY_CLASSES_ROOT. For example, if you're used to doubling clicking a .LOG file and having it open in Notepad, scroll down until you find a key called .log and click on it. You'll find something under the default value (right-side of regedit), usually its txtfile.
Now continue to scroll down the HKEY_CLASSES_ROOT keys until you find txtfile. You'll find a bunch of stuff under that key. You're probably looking for something like this.
You'll have to duplicate both keys for your application, depending on what you want to support in your app. If you're familiar with command line arguments work, it'll be obvious what's going on in these keys.
Now all you have to do is add command line argument support to your application and you'll be all set.
[EDIT]
Oh yeah! If you screw up your registry, it's not my fault! My hand wasn't on the mouse when it happened.

that's too simple in c#
Microsoft.Win32.RegistryKey reg= Microsoft.Win32.Registry.ClassesRoot;
if(reg.OpenSubKey(".myE")!=null)
{
reg=reg.CreateSubKey(".myE");//your application extension key
reg.SetValue("","MyApp");//reference to the key contains shell commands for your extension
reg= Microsoft.Win32.Registry.ClassesRoot;
reg=reg.CreateSubKey("MyApp");//the key contains commands windows will use when find your extension
reg=reg.CreateSubKey("Shell");
reg=reg.CreateSubKey("Open"); //open commond
reg=reg.CreateSubKey("Command");
reg.SetValue("","c:\\windows\\notepad.exe");//the path of your application which will open the files with your extension
}
}//already exists

I never said I would write it for him. I just pointed out how to figure out what's involved in getting it to work. It's up to him to write the Registry modification code.
