c# OpenFileDialog problem

[Sonia Igla]

Hi.
I use in my windows c# project External
Dlls(Assembly.L oadFrom(dllName );...).
All work fine.
I add to one of my forms using of OpenFileDialog. First time I call
this form
It works. Next times I get Error: "File or assembly name Extended.dll,
or one of its dependencies, was not found." in all modules this dll is
using.
This happen only by OpenFileDialog selects files (by cancel not
affect).

Help me please by this trouble.
Thanks Sonia

Hi Sonia,

Is it possible that your assembly uses other assembly "Extended.d ll"
that is not loaded?

Re: c# OpenFileDialog problem

Hi,

Is extended.dll used in your project somewhere? , If so is it used in the
code that gives you the error, are you sure that its loaded before?

Does the error occur inside the dialog, or in your code after the dialog
closes.

If no post more details.

cheers,

Re: c# OpenFileDialog problem



The extended.dll using in several parts of my project is loaded by:

Assembly a = Assembly.LoadFr om(extended.dll );
Type theType = a.GetType(nameS pace,true);

int paramLen = param.GetLength (0);
Type[] paramType = new Type[paramLen];
for(int i=0; i<paramLen;i++ )
{
paramType[i] = param[i].GetType();
}
ConstructorInfo ci = theType.GetCons tructor(paramTy pe);

try
{
bc = (BaseControl)ci .Invoke(param);
}
catch(Exception ex)
{
throw new MeteoException( ex.InnerExcepti on + "." + ex.Message);
}

Extended.dll is my assembly and contains some modules and forms. The
problem OpenFileDialog component is used in one of this forms of
extened.dll.


This all works fine in my project.

The problem occur after first time call and open with OK result (Cancel
not) OpenFileDialog in one of modules (forms) of extended.dll.
After that, All Loadings this dll by Assembly.LoadFr om (
extended.dll) gives error.

If not Open this OpenFileDialog( OK Result) the same forms works fine.

Thanks Sonia.

Re: c# OpenFileDialog problem

No it is not.
Extended.dll is my Assembly containing some forms that are called by
Assembly.LoadFr om(dllName) command and creating by
theType.GetCons tructor(paramTy pe).

One of this forms (of Extended.dll) include OpenFileDialog.
After using this form and open with OK Result the Dialog
I Get Error by all forms (of Extended.dll) create.

It not occurs if not open with OK Result the Dialog.

The same program reexecute (without rebuild) gives the same schema of
problems (First loading with OpenFileDialog call works, after ...).
Consequently all used dlls are on there places.

Thanks Sonia.

I found answer on my problem.
OpenFileDialog RestoreDirector y must be true.
