There are the Registry-Class and the RegistryKey Class

You can get all RegistryKey-Names with a funktion in the RegistryKey-Class:
string[] name = Registry.LocalMachine.GetSubKeyNames();

you can open every subkey and on this you can get all SubKeyNames of this Subkey.

So you can look up every Key, Check its values and if you like Delete it with the Funktion DeleteSubKey

Hey Guys,

Been playing with MSH & WinFX and put together a little MSH script to build all projects on your machine which you may find helpful (especially for building the samples)

MSH> $files = (dir . *.csproj -Recurse)<br />
MSH> foreach ($file in $files) {<br />
 cd $file.Directory.FullName;<br />
 msbuild;<br />
}

60% of statistics are made up on the spot

Problem saving XML file through XmlDocument

Can anybody please help me in resolving this Issue?

I am trying to open and save a file saved on my local computer through XmlDocument in a Smart Client Application which accepts the Xml data from a web service in the form of a string, which I update to a file in my local machine.

Following is the code..

RSMService lRSMService = new RSMService();
InputOutput IOComplianceGroup = new InputOutput();

IOComplianceGroup = lRSMService.GetSpecificData("procGetSanitizerLog",IO.propertyDataset.Tables[0].Rows[0]["StoreId"].ToString(),false);

if (IOComplianceGroup.propertyResult == Result.Success)
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(IOComplianceGroup.propertyXmlDocument.OuterXml);
System.IO.FileInfo FI = new System.IO.FileInfo(path1);
if(FI.Exists == false)
{
FI.Create();
FI.Open(System.IO.FileMode.OpenOrCreate).Close();
}

FI = null;

try
{

xmlDoc.Save(path1);

xmlDoc = null;

}
catch (Exception ex)
{

MessageBox.Show(ex.Message.ToString());
}

}

Thanks in advance

MD5 checksum test for COM-DLLs

Re: MD5 checksum test for COM-DLLs

13-Dec-05 1:04

Hello,

I want to calc and test the checksum of an COM-library I use in my project. But as I got as AssemblyLocation only the reference to the Interop-file I don't know how to test the checksum of library itself.
Is there a way to get the reference to the DLL behind an interop resource? Does anybody know?

Thanks,
Ingo

(You've probably found your answer already, but oh well.)

I'm not positive about this (and am too lazy to doublecheck), but I think the wrappers for the COM objecs in the interop assembly will have the CLSID attached to them via attributes. Assuming that, one could then use reflection to grab the CLSID for the COM wrapper being used, then open up the registry key associated with that CLSID and grab the location of the binary.

Example:

For the COM object MyOldCOMObject with CLSID "4C6055D8-84B9-4111-A7D3-6623894EEDB3", the interop assembly should generate something like this class definition:

[Guid("4C6055D8-84B9-4111-A7D3-6623894EEDB3")]
public class MyOldCOMObjectClass : IMyOldCOMObject
{
}

If so, then the registry should have a key like this:

HKEY_CLASSES_ROOT\CLSID\{4C6055D8-84B9-4111-A7D3-6623894EEDB3}\InprocServer32\(Default): C:\MyOldApplication\MyOldCOMServer.exe

Hi From Australia,
I Have a project that acesses an excel file that I have stored in the bin folder of my project. All I do is click a button and it opens excel - this works fine on the development computer but when I try it on other computers (Slightly Older) the file opens but is locked and read only saying that the file is already open. I can find the file through excel on the computer my program is installed on but not from my program. Any Ideas?

I'm confused. Does it open in a "locked and read only " state or is it that you can't find the file from your program? My guess is that your program is referencing one version of the Excel object on your development machine and the production machine has an older version installed. For example you may have Office 2003 installed on your dev machine (I believe its the Excel 11.0 object) while the production machine has Office 2000 (I think it is Excel 9.0 object). Check to see which version of excel is installed on each machine to see if they match.

i am new at programming in Microsoft Visual Basic 2005 Express Edition.
i have a form (switchboard has multi button to ectain apps) which when i click a button it runs a .exe
(System.Diagnostics.Process.Start("C:\program files\World of Warcraft\WoW.exe")
it all works but i would like to able to put a button which adds apps whotout having to go in vb to edit.

i would also like to know how do i convert my .net v2 to be able to run on a pc without having to install .net v2 (windows xp and 2000)if possible
thanks Patrick

I can't understand why people keep asking this. If it wasn't required, why do you think you need to install it ? There are expensive ways of doing this, none that are cheap, free, or a good idea.

patrick king wrote:

I guess you're saying you want to add buttons dynamically ? I would say the best way to do this is to add an XML config file which contains the paths to run and the button text you need, then iterate over it on startup and create buttons accordingly. A drop down list is a much better UI for this, no dynamic controls needed.

But why do you need an exe to do this ?

Place a shortcut to your EXE in the startup folder.

The best suggestion (without typing code here) is to tell you to take a look at the code that gets created when you add a control to a form in the designer. You have to do all the same stuff, just at run time.

I need to show an image on a Form, and not on the designer, but from the code

How can I do it?

On the Form itself? You could use the BackgroundImage property.
VB.NET

Me.BackgroundImage = New Bitmap("filePath.bmp")

this.BackgroundImage = new Bitmap("filePath.bmp");

Managed C++:

C++/CLI:

this->BackgroundImage = gcnew Bitmap("filePath.bmp");

ps: I think you shoud use Namespace System::Drawing.

Say I have a project, a windows form project. In it I create one or more UserControl derived controls. I would think they automaticaly show up in the Toolbox, but apparently not. So how do I get them to show up? If i'm creating them within an EXE project (at least in VC++) I am unable to add teh EXE in the choose item when right clicking on the toolbox, so I'm wondering what the steps are to get the control on there in drag and drop fashion, without having to resort to hand coding it?

Thx.

Size of a Folder

Well, I've been trying to get the Size of a Folder with .NET without using Recursion. There dosn't seem to be any property for it and all my searches have given me only ways of getting them using Recursion, which I want to avoid at all costs. Any Advice, Guys ?

The directory/folder structure itself is recursive and as far as I know there is no such information stored in any folder. Technically it could be done but if a file changes one should update this information of all the parent folders and that could make it quite expensive.

You could a tree structure containing this size information yourself and have it kept up to date by means of a service. Then you only need to ask that service for the size and you would have the answer immediately. But this is far more complex than the recursive algorithm. A unwanted side effect is that such service would take up CPU time and probably would decrease the performance of your disks. Do you have any requirement that ask for instantanious information?

If you just want to avoid recursion you could make an iterative directory walking algorithm but that would imply you should keep track on a stack where you have been. It might be a bit faster but it is harder to code.

Thanks Rob.

But, Yes, My App does require Instantanious Information. It is something like (Treesize), but also adds that it can actually operate on the files and folders. And, Since it uses a Chart and by it's Very Nature, changes the information about directories often, it does need instantinous Information...

And, I suppose I'd be doing some benchmarks about the time required to get the size of them by Recursion and iteration, but I think that It'd take a lot of time, especially for rather big Folders like the Program Files folder....
