Does anyone have conclusive evidence as to wether or not a .NET application can make use of the App Paths registry key? I created a tentative test app and it doesn't seem to find the additional DLLs, but I wanted to get some corroboration.
Thanks,
Scott.

Yes, it can be done. Post your code fragment here, and we can see what's not working.

I would but I don't think the problem is in the code.
I have an application that uses some common DLLs that could potentially be shared by some of our other products. Ideally, we would strong-name these DLLs and put them in the GAC, but (at least right now) I'm not allowed to do that. The next best thing would be to install the shared DLLs to a common folder.
In the installer (InstallShield 12), I create the following registry key:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Console.exe
(The name of the app in this case is "Console.exe")
and then create a Path string value with the following data:
C:\Program Files\Company\Product\; C:\Program Files\Common Files\Company
When I try to run Console.exe, I get an error saying that it can't find one of the required components. If I copy the DLLs from the common folder back to the local application folder, everything works properly.

I have a problem with VB and graphic. I can generate all the graphics i want but saving is only possible in bitmap.
I need to scale and modify the output of my software with AI or Corel Draw but do not get results. Vectorizing is not an option. I tried various vectorizer lice Corel Trace and the results are not what i expect.

Have you found a solution to the problem?

Hi,
i want to ask can i call a crystal report without reportViewer control. i mean is there any way to call a report directly in some way??
basically i'm using c# express edition which do suports SQL server 2005 but doesnt support crystal reports. so i installed crystal report 10 seperately and begin using it. now in my C# IDE if i go to add Item then crystal report icon doesn't apear. also there is not report viewer control in the the controls area. so i asked this question. if there exists no way then sugest me what should i d0??
hope u'l respond for my satisfaction.
as far as my introduction is concerned i'm a student of BS doing my final project, i'm using .net since 1 year but crystal reports are new for me.
regards
thx in advance!!

hi there.
report viewer control is a part of dll so you wouldn't be ablt o use it serperately. there might be some other options, but here is a rough-one.
export the report to a file of desired format and then view in explorer or other application that supports the
format you chose.
Rep r = new Rep(); //report object
r.ExportToDisk(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat , "C:\\myreport.pdf"); //exporting as pdf file
ProcessStartInfo info = new ProcessStartInfo("iexplore.exe","C:\\myreport.pdf");
Process.Start(info);
if you cant find something more robust, this may be usefull, at least on educational level.
regards.

I am doing performance measurements and would like to use a native executable to avoid having JITs occur during performance timing. How does one execute an ngen-generated executable?
There are blogs and MS documentation everywhere that talk about how to use ngen, but I have not found a single place that says how to execute an ngen-executable! 
Here is what I tried. Compile:
% csc helloworld.cs
Then install in the global assembly cache:
% ngen install helloworld.exe
Then go to the assembly cache and try to execute:
% cd c:\windows\assembly\helloworld\[hex string]
% ./helloworld.ni.exe
This gives the error message: c:\windows\assembly\helloworld\[hex string\helloworld.ni.exe is not a valid WIN32 application.

|
|
|
If I remember correctly, you still run the "normal" helloworld.exe file. The runtime will figure out that you have a corresponding native image and use that instead.

I tried that before posting - I don't think it works. The md5 sum of helloworld.exe is unchanged by running "ngen install helloworld.exe".

We have various enumerated types in our system and we obviously want to present human readable values that can be easily configured by our UI folks rather than the cryptic identiofiers that we use in the code.
Just wondering what facilities are available in .NET 3.0 to accomodate this kind of thing. In the old days, I would use a string resource and a mapping table for the lookup.
Anybody got any cool/slick/modern ideas on this?
Thanks

The following will print "Blue" to the console:
namespace CSFoo
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine(ETest.Blue);
}
}
enum ETest
{
Red,
White,
Blue
}
}
|
|
|
|
|
I need to provide a secondary string description of the enum value.
Rather than "Blue", I would want to map that value to a human friendly string such as "The Color Blue".
Make sense?
|
|
|
|
|
The easiest way to do that would be to use a hashtable to map "Blue" to "The Color Blue".
--
Rules of thumb should not be taken for the whole hand.
|
|
|
|
|
namespace CSFoo
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("The Color {0}", ETest.Blue.ToString());
}
}
enum ETest
{
Red,
White,
Blue
}
}
|
|
|
|
|
should have extended subject to say
"that can be easily modified by non-programmers outside of the .cs file"
I think I can probably build a ResourceDictionary in XAML that would provide a basic lookup capability at application scope. Thus my UI guy can tweak the XAML and I can simply do a FindResource using the enum value identifier as the key.

Are you looking for something that can be modified at runtime or just modified by a "non-programmer" at design time?
You can also look at using the DescriptionAttribute and using a little bit of reflection to retrieve the attribute value at runtime. I believe the strings used in the attribute constructor can be referenced from a resource file.

No runtime modification or localization needs.
Decided to go with a simple XAML declaration of strings in Application.Resources and use typename.value as key (ID) name.
No hard coded string IDs, and easy for non-programmers to maintain (notepad) in a centralized location.

The meaning is writed as
"If the member was not serialized, the CLR will leave the members's value null rather than throwing an exception."
Visual Studio does the same thing as if this attribute was not used, so why should anyone use it?
Or is it to garantee compatibility with .Net 1.x?
|
|
|
|
|
It is part of the changes made to serialization in .NET 2.0 to help alleviate the versioning issues that can be encountered when dealing with serialized objects.
If you have version 1.0 of your product that serializes an object and then you create version 2.0 of your product that adds new fields, you would get an exception when you tried to deserialize the 1.0 version of the object. By marking the field with the OptionalField attribute, the object will be deserialized properly and the "missing" fields will be null.

Strange, I can't simulate an exception, what am i doing wrong?
1. Create a class
2. Create an object instance
3. Serialize this object
4. Add a field to the class (value or reference)
5. Deserialize (I supposed .Net would trow an exception here because there's a new field that isn't serialized, but it doesn't)
I think it's just .Net 1.x that generate an exception

By using 'BinaryFormatter', the .Net Framework 2.0 doesn't give an exception if you do not use the 'OptionalField' attribute.
But if u use the 'SoapFormatter', the meaning of the 'OptionalField' attribute becomes clear.
