Does anyone know how to reference to an assembly which is generated in memory from another assembly also generated in memory (compilerParameters.GenerateInMemory = true)?

Hi!
I have a multi file assembly that exists of two modules and a .dll that contains the manifest. If I add a reference to the manifest dll into my c# project, I can access the types within the modules, however they are not shown in the intellisense window.
Is there any way to make them appear in the intellisense window?
Thanks in advance!

Hmm... they are shown for me... are you adding the projects to the same solution? I am

Huh? Which version are you using?
I have two c# module that I compile from the command line using /target:module, lets say part1.module and part2.module. Then I use al.exe to create a manifest for these two modules (foo.dll).
If I add foo.dll to the references list (only the file foo.dll, no projects), I don't see any of the types of the modules. However, I can use the types and compile the program.
I got a post in microsoft.public.dotnet.languages.csharp that this is a known limitation (or bug if you want so).
It would have been *sooo* nice

I have the following problem :
- I devellop new inheriteded forms (visulally) , from a base form. The base form already contains some controls , among others some buttons. This works fine, but when I try to resize the new form , and I build the project, the Visual Studio designer just moves my bottons to the right . If I relocate the buttons, the same happes : they just don't want to stay put.
Different people told me they have the same problem , but didn't find a solution. Can anyone help ?

I need to compare content of two data fields of the same "unknown" type.
Here's the code example that doesn't work because it compare objects instead of data fields.
protected bool CompareRows(DataTable WorkDataTable, int ColumnIndex, int RowIndex_A, int RowIndex_B)<br />
{<br />
if (WorkDataTable.Rows[RowIndex_A][ColumnIndex] == WorkDataTable.Rows[RowIndex_B][ColumnIndex]) return true;<br />
else return false;<br />
}
So what I need is explicit type casting, but as the data type of the column is unknown it must be done on the runtime.
Therefore my question is: Is it possible to cast types on the fly?
Can I use DataType property of the DataColumn for type casting? How?
Any suggestions (other than .ToString() conversion)?

Thomas,
The Convert.Equals() method should do the trick for you here. As in the following:
DataTable Table = new DataTable();
Table.Columns.Add(new DataColumn("Test1", System.Type.GetType("System.DateTime")));
Table.Columns.Add(new DataColumn("Test2", System.Type.GetType("System.DateTime")));
DateTime s = DateTime.Now;
DataRow r = Table.NewRow();
r["Test1"] = s;
r["Test2"] = s;
Table.Rows.Add(r);
bool s = Convert.Equals(Table.Rows[0][0], Table.Rows[0][1]);
if(s)
{
return true;
}
else
{
return false;
}
Hope this helps.

Thanks Don
It works fine for current purpose.
But would still wanna know if it's possible to cast types on the fly using Sytem.Type object or some adequate property.
If someone know the asnwer please share it.
Thanks.

We intend to give our Assembly out side our group and it'll be used in any .NET application including ASPX and ASMX.
To restrict unauthorized use of this Assembly, it will demand a X509 certificate through PublisherIdentityPermission.
We want to handle distribution process in the following way.
1. Sign the Assembly which we want to give out side our group with a Certificate.
2. We will also sign caller assembly/application with the same Certificate, there by authorizing them to use our assembly.
3. Callers will Assert PublisherIdentityPermission before making actual call to our assembly (to stop the stack-walk as any upstream apps do not need to be signed), See sample code at the end.
As far as the choice between PublisherIdentityPermission Vs StrongNameIdentityPermission, we decided to go with PublisherIdentityPermission.
Because we felt it’s easy to work with certificates.
If someone could validate our thoughts, that would be great.
Sample Code Snippets
OurAssembly.dll Code
namespace Microsoft.MSCOM.MemberServices.Samples.PublisherIdentityAssembly {
[PublisherIdentityPermissionAttribute(SecurityAction.Demand, CertFile="ramCertificate.cer")]
public class ModuleClass {
public void ModuleMethod() {
Console.WriteLine("PONG: from ModuleMethod in myModule.");
}
}
}
CallerAssembly.dll Code
namespace Microsoft.MSCOM.MemberServices.Samples.PublisherIdentityCaller {
public class CallerAssemblyClass {
public void AssemblyMethod() {
X509Certificate cert = X509Certificate.CreateFromSignedFile("CallerAssembly.dll");
PublisherIdentityPermission pip = new PublisherIdentityPermission (cert);
pip.Assert();
ModuleClass mod = new ModuleClass();
mod.ModuleMethod();
Console.WriteLine("Reverting Assert.");
CodeAccessPermission.RevertAssert();
}
}
}

How do I create a XML as an attribute or component of a object in C#?
|
|
|
|
|
I'm not sure exactly what you mean. However you may be able to solve your problem by simply reading your XML into a string &/or an XMLDocument object in the class.
<code>
string s = getMyXml();
XmlDocument x = new XmlDocument();
x.LoadXml(s);
</code>
I havn't tried either of these, so they may not do exactly what you expect!

In a Windows form, I have a treeview/listview pair in a file backup app that behaves like Windows Explorer, with checkboxes for each element to keep track of what's been selected.
I'm looking for the best way to cascade a treeview check/uncheck from a parent node to all children nodes... for example, if I check "c:\winnt", I want any child nodes to also be checked, to show that everything underneath is also selected.
I'm wondering if .NET provides any built-in way to do this, or if I have to come up with my own algorithm to traverse the nodes myself... seems like a common operation in treeviews...
thanks for any help.

vlusardi,
There is no built in way to do this, however a simple function like the following should do what you want:
private void CheckChildNodes(TreeNode ParentNode)
{
foreach(TreeNode t in ParentNode.Nodes)
{
t.Checked = ParentNode.Checked;
if(t.Nodes.Count > 0)
{
this.CheckChildNodes(t);
}
}
}

Don,
Thanks again, I knew I'd be doing some recursion if I couldn't find any built-in functionality, just didn't realize it would be that simple...

Hi All,
I have a base class and then a class that derives from it. In the base class I have a virutal function. My question: Since the function in the base is virtual why do I still have to provide the new or override keyword? I don't recall having to do this in C++ (although I could be wrong). Which one (new or override) is be better to use? Both fucntions return the same type.
//Just added
I just tried to add the override keyword and get this compiler error: A member marked as override cannot be marked as new or virtual
Isn't this sort of a catch 22 type thing?
When I remove it I get this complier error: ToolTabsCS.ToolTabSplit.InitializeTool()' hides inherited member 'ToolTabsCS.BaseTool.InitializeTool()'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.
Thanks.

In my article C# Keywords[^] I describe both and give some examples.
Hope that helps.

No. If you mark something as override then it's automatically virtual, if you mark it as new then it's completely hiding the base class implementation so you can decide to make it non-virtual.

Thanks for the replies guys. The problem was that I was keeping the virutal keyword in as well as override, didn't know you had to remove it. Thanks again.

I have a project I am working on where I need to be able to programmatically search a remote SharePoint Portal Server for specific information. I would like to accomplish this using .NET, rather than going through Web Part developement (which at this point is a little over my head).
Has anyone run across a .NET wrapper library for SharePoint or some code that will allow me to interact with SharePoint? I found (I think here on CP) a set of classes that someone developed to interact with the Exchange WSS, but it seems to work only with that and not with SPS (which is based on the Exchange WSS).
Many thanks

SharePoint version 2 (which comes with Office 2003 beta 2), is written with ASP.NET. I'd think that would be what you're looking for.

Using various articles found here on CP I am putting together a small systray application to take a screen capture, resize it, and then upload to an FTP server.
I have everything working so far with the exception of the ftp upload, this is because this article :
http://www.codeproject.com/csharp/.net_ftp_upload.asp?target=ftp%7Cupload
Has a dead link, when you try an download the project files.
Does anybody know of any other articles of a similar ilk?

Hi!
(I hope this is the correct forum for this question)
I have a bunch of .net modules, written in different languages (managed c++ and c#). Now I'd like to link them all together into one .dll. I tried using al.exe, but this tool only generates an assembly manifest, that refers to the external modules rather than embeds them into the dll.
Then I tried this: I disassembled all modules with ildasm and then tried to re-assembly the .il files with ilasm into one final .dll. Hower this does not work, as my modules contain native functions.
What can I do?
Thanks in advance
- Andre
