First of all, is it possible usign .NET remoting feature inside a .NET
applet loaded into a tag object inside an HTML page ?
<object id="myID" height="150" width="300"
classid="http:applet.dll#test.applet">
If not please can anyone explain why ?
I think yes and so I'd written a small example immediately I've met a
problem.
I'm using .NET Framework v. 1.1.4322 and it's the only version
installed both client side and server side.
My test applet is correctly loaded into IE client but when I try to setting programmatically the remoting I aways obtain a SecurityException even if the assembly is strong name signed and client side fully trusted.
The exception is the following: <br />
System.Security.SecurityException: Request for the permission of type System.Security.Permissions.SecurityPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed. <br />
at System.Security.CodeAccessSecurityEngine.CheckTokenBasedSetHelper(Boolean ignoreGrants, TokenBasedSet grants, TokenBasedSet denied, TokenBasedSet demands) <br />
at System.Security.CodeAccessSecurityEngine.CheckSetHelper(PermissionSet grants, PermissionSet denied, PermissionSet demands) <br />
at System.Runtime.Remoting.Channels.ChannelServices.RegisterChannel(IChannel chnl) at test.applet.Check()
Could anyone help me please ?
Best regards

1.I create a strong typed dataset.
2.I bound the table from the strong Typed dataset to a DataGridView.
3.User Click on a row and press "Select" button. I can just cast the selected row with code below:
<br />
this.returnedRow =<br />
(TypedDS.MasterGroupSearchRow)this.dgvMasterContract.CurrentRow.DataBoundItem; <br />
4.At this moment the
this.dgvMasterContract.CurrentRow.DataBoundItem is (TypedDS.MasterGroupSearchRow)
But if After Click on the column header .. problem come out ...
this.dgvMasterContract.CurrentRow.DataBoundItem will become System.Data.DataRow.
So code below will fail ..
<br />
this.returnedRow =<br />
(TypedDS.MasterGroupSearchRow)this.dgvMasterContract.CurrentRow.DataBoundItem; <br />
Is there anyway to solve this problem ? or is there anyway to preserve it original typed row ?

Check the type before you process the OnClick event?
Is this a web grid view or a winform gridview?

Hello!
Ive got a solution with about 10 projects. I recently changed assembly version in all projects from [assembly: AssemblyVersion("1.1.0.0")] to [assembly: AssemblyVersion("1.1.0.1")].
When I now rebuild the solution and run the program I get this: System.IO.FileLoadException: The located assembly's manifest definition with name 'X' does not match the assembly reference.
File name: "X"
What did I miss?
/Regards

When you set your references between projects, did you set the reference to another projects .DLL file, or to the project itself?
If you set it on the .DLL file, this can cause the problem your having.

Hello Dave
I set in on the project itself.
/Regards

OK. If that's the case, then you have the older project .DLL's copied into the .EXE's Debug and Release folders, or somewhere else on the PATH. Search the drive for the names of the .DLL's and see if you have stray copies running around.

I have a similar problem.. but changing the reference to project reference didn't resove the problem...
In visual I clearly see reference to a project with version 1.1.x.1
But when I check with the .net configuration utility the assembly dependecy points to version 1.1.x.2
And If I check with lutz .net Reflector I see the reference to version 1.1.x.1
But when I test my app it is clear that the dependecys in .net config utility is right because it gives an error tha it can't find 1.1.x.2
This seems so strange.....
Please help !
thank you

Same answer. Search the drive and find all the copies of the .DLL's involved. Wipe them all out. If you have them registered in the GAC, unregister them first. Once you have them cleaned up, rebuild the entire project. Make sure of your project dependency order first, the rebuild the entire project.
You can find out more about how the runtime locates and loads assemblies here[^].

Thank you for this usefull information, But I'm still confused why you get different references on the same dll with reflector and .net configuration utility ...

I don't know. I haven't seen that behavior and I can't duplicate it myself.
I keep my Assembly Versions completely manual. That means that there are no * in the version assembly version numbers. I also don't copy my .DLL's around and I don't set references to them unless they are libraries that I use in multiple projects and I've installed them in the GAC. Otherwise I set references to the .DLL's Project, not the .DLL itself. This keep versioning nice and neat and avoids problems with "whatever version cannot be found" errors.

Search for DShowNET on CP.
As of how to accomplish that have you ever tried Google?

hi there
i have a form with many controls. when i will make final version my apllication will run slow because of that manny controls???
all my controls are from standard like labels, combo, textbox's ,datagrid..etc
if the answer is yes, what to do to avoid slow motion in use of my software?
|
|
|
|

Standard controls are going to be fine. Really, it depends, if you have a speed issue, then you need to look at what could be causing it, but with the speed of PCs nowadays, it's not likely you need to worriy

How do i de install .NET framework 1.1 and re install it. i have .NET framework 2.0 on the same machine and its a windows 2003 server.
How do i do it
|
|
|
|
|
I suspect some thing is messed up with the .NET 1.1 and so i want to reinstall that
The reason i came to that conclusion is that a .NET application i wrote previously which was working previously well is now generating an error
"Application has generated an exception that could not be handled process id = .... Thread id = .... "
The same application works perfectly on my computer and i know that it worked perfectly two days before too on one of our customer computer and some thing was done on that server afterwards.
Well i want to know if there is an easy way to remove it and reinstall it its on windows 2003 server. It does not show up in Add Remove Programs. When i just run dotnetfx.exe(redistributable package) it says its already there.

Seems more likely to me that the PC it's crashing on is showing you a problem in your code that depends on user settings or something like that.

Is there anyway of reducing the runtime of the .Net projects that I have done. Currently its taking too muh time.
|
|
|
|
|
That's a really vague question. What do you mean by "reducing the runtime", "taking too much time"?? Too much time for what?
The biggest problem with performance is writing inefficient code...

you should have to Modulate your programming style. And In ASP.net you can use This Tag in web.config file <compilation defaultLanguage="vb" debug="false"> when you filnaly uploading other time you can use
<compilation defaultLanguage="vb" debug="true">

I have done a few projects in .Net framework 1.1. I have found that these projects do not run in systems without .Net framework installed. There is always an "initialization error" that comes up. Is there any way of overcoming this. Plese Respond.

No. The Framework is hte runtime library. You can't have a .net application without the .net framework any more than you can have an mfc project with out the mfc runtimes, or a vb project without the vb ones. What you should do is have your installer check for the presence of the framework and tell the user it needs installed. "This app needs the .net framework installed. you don't have it. Click here to download (link to MS download location)". Alternately you could write a very small c/c++ launcher app that tests for hte framework, and spits up an error box if it's missing. IF installed, it luanches your main app.
if you're truely bound and determined to avoid hte framework, there are several expensive products that can compile .net code down into a native win32 app. My understanding is that they're all somewhat quirky as well, so you should start using them early in the dev cycle and test extensively to make sure they're not breaking anything.
