I'm dealing with what I think might be a bug in Visual Studio 2010 Professional. I have several forms in my application (WinForms, .NET 4x) which use a SplitContainer to provide a button panel (OK, Cancel, etc.) at the bottom of the form. I set the SplitContainer.FixedPanel to Panel2 and SplitContainer.IsSplitterFixed to true.
The form in question has SplitContainer objects nested 3 deep with DataGridView components in 3 of the panels and buttons in the 4th.
Now every time I press F6 to compile, the main parent SplitContainer.SplitterDistance is incremented by a value of 3. This happens with each F6 press until the components on Panel2 are being truncated on the lower edge of the panel.
I tried to duplicate the behavior by adding the same components to a new form. It wasn't until I added DataGridView components to some of the panels that the SplitterDistance of the main splitter component changed on compile. I'm guessing that the problem has to do with the complexity of the form and not with the DataGridView components specifically.
In general, I've had several problems with components not maintaining their positions during development. I can finish working on a form and return later to find everything moved around. Very frustrating 
Has anyone else seen this behavior? Is there a workaround?
Thanks....

I've seen similar things even going back to VS 2002, but not that exact thing. And I don't know a way around it.
Can you reset the position in the Load method?

I might be able to but having to position each component at run-time wouldn't be practical and I won't know for certain which components are mobile unless I check each component on each form with every compile.

Make all your source-files readonly before building. As far as I can see, compiling does not modify the original sources - but if the window is open in the designer, then it might try to update it's contents in the Forms Editor.

Your suggestion led me to another discovery. The value is incrementing when the IDE loads the form; not when it compiles. Apparently, the IDE reloads the form after a build and that's why I associated it with compiling. This is even worse because I can't very well change it to read-only as it's being loaded for editing. If I can't trust the IDE to load a form without modifying it, this means I have to check the position of every component on every form I edit before I save. This can't be right.

Is it the IDE that's modifying a property, or are is your code initializing some properties there?
I've seen quite some cases where the mere act of opening a form causes the damn thing to check-out and do all kind of weird things. It's usually an initialization-issue. DevExpress components will often show the same behavior.

There's nothing in the code that would change the SplitterDistance property. The only properties I'm setting are BackColor, ForeColor, Font & ShowInTaskBar.

Are you sure that they don't affect the splitterdistance indirectly? A label with "autogrow" set to true might resize if another font is assigned.
Does it still happen if you don't set the properties?

Yes, it does.

Doesn't seem to be standard behavior; a splitcontainer on a form does not change it's position. Not on building, not on opening.
Any of the containing controls doing a resize? Anything resizing the form? Any code that references the inner panels and manipulates either height or width?

There is a resize method for the form but even when I comment it out, I still get the same behavior. I'm seeing this on multiple forms in the application (mostly more complex forms). The form in question has 3 Nested SplitContainer components where 3 panels contain DataGridView components. All the forms in the application are inherited from a master form that sets font, color, etc. as discussed above. I'm only noticing this behavior on the more complex designs (child forms with lots of complex controls).
Other than the form's resize method, the only other method that even remotely deals with resizing is that where of the DataGridView components calls it's AutoResizeColumns method.

My working environment:
Windows 7 Enterprise SP1, 64-bit OS, VisualStudio 2010 Premium.
My scenario:
I have a windows solution that needs to be published over a VPN to the “Live Server”.
When I publish the solution to the “Test Server”, it publishes fine, installs without problems, and the testers can do their stuff.
My problem:
When I publish to the “Live Server” over the VPN, the necessary files are copied over (the following files, where * represents the name of various classes, projects within my solution, etc: *.dll.deploy, the *.exe.manifest, the *.application, the *.exe.deploy) – 64 in total.
I have physically watched the copying process to verify that all the files are copied over.
The Publishing Folder Location and the Installation Folder URL are the same, as indicated on the Publish tab in the Properties of the Start-up project.
At the end of the copying, I get a VS error list with between 5-7 errors, and then a rollback starts that deletes those 64 files from the deployment location. Those errors ALWAYS include a combination of 9 specific files, and the files shown in the error list are not the same every time.
The error message:
“Failed to copy file ‘…filename…’ to ‘…deployment location…’ to the website. Unable to add file to ‘…deployment location…’ The specified network name is no longer available.”
While the copying took place, I pinged the “Live Server” with the –t tag to ensure that I can spot a drop in connectivity.
My request:
Is there anyone that can assist me, or point me in the right direction to sort out this problem? Is there something that I am overlooking? Any advice will be highly appreciated.
I am thinking of:
Since nothing changes between be publishing to the “Test Server” and the “Live Server” except for the deployment folder location, can I plainly copy the 64 files from the “Test Server” over to the “Live Server”?
Thanks in advance.

how we create treeview and its data base in c#.plz send me coding

And what type of TreeView? Is it a web application? Or is it a WPF app? Win Forms? What type of database?
You do realise that the forums aren't for asking for people to send you complete code solutions don't you? The accepted form here is that you write your own code, and when you have a problem you post a question with a relevant snippet of code, along with a detailed explanation of what the problem you are having is, what you have tried so far, and any relevant exception information.
As Code Project has a large number of articles, it's a good idea as well to search through the articles looking to see if there is anything in there that you could learn from. They generally have complete applications, and they are also rated so you can get a pretty fair idea what people think of them so that you can determine whether or not you should put much trust in the article content.

Noone is going to "send you coding" because we're not in the business of writing your code for you.
If you can't create the database on your own, according to your own business model, there's really no reason to start writing any C# code because there's no database to write code against!

Here's the code for a view of a tree:
.oo689ou.
98O9PS9689P
S9968D8O886'
`9O89S9889'
``|&|''
|%|
|%|
.:%:. mh
I hope that's useful

I feel bad about voting 5 here. It definitely fulfils the treeview part, but isn't c#. This should sort out all the requirements  :
{int i=9;}
bool l=true;
{l=l&&l&&l&&l;}
bool k=l||
l||
l||
l||
l||
l&l||l;;

Your version is certainly better
P.S. Oh, wait, we forgot the database  . Back to the drawing board...

Hi,
last year i develop a software in c#(WPF) so i deployed it and install to the employees machine with the name softbase2011 now my company need the same software but with the new name softbase 2012and just change the graphic interface and the string of the database (because each year they use a new database because they change price and data ,it is a travel agency) but they wish keep and use also the old software (softbase2011) so when i deploy the software softbase2012 i can not install it because appear an error that advice already there is a software with the same name installed on the computer then i ask you how i can install 2 softwares just changing the name on the same computer???
Thanks so much for your attention .
Cheers

If one is called softbase2011 and the new version softbase2012, then there should be no conflict. You need to investigate where the duplication exists, and correct it.

hi Richard,
that's strange it says already there is a version installed on the computer but in reality the version installed is softbase2011 so i don't understand why derosn't allow me to install the new version changing the name of the app.
thanks so much for your response

Well some element or value that you are using has the same name in both versions so you need to investigate to discover which it is.

You have to understand how Windows Installer works. Your installer had a ProductCode and UpdateCode that's the same between both versions of your app. That's why your new installer says it's already installed.
Without modifying anything, your only work around is to uninstall the previous version of the app first, then install the new one.
A quick "fix" to get your new installer to work would be to change the ProductCode. The UpgradeCode remains the same and this is going to tell MSIEXEC that the new app upgrades the old one.

Hello,
I recently began working on a project in C# .Net, written in MS Visual Studio 2010, where many things are at least peculiar...
All files are in root directory, meaning there are no subdirs.
Files include several classes which, in best case, may belong to the same or a similar fact.
Even if there is only one Class in a .cs file, it doesn’t always have the same name, meanig for a Class Car the file may have a name Frm_View.cs, in other words completely irrelevant to the class name.
Hungarian notation is being used, like in the old MS times.
There is an enorm amount of internal, static and both internal static variables and functions.
There is no inheritance between classes.
There are no interfaces.
It seems to me that it is about an old C programm, which has been ported into C#, but only as far as syntax concerns.
What do you think?
