I have a VS2010 project that I want to move back and forth between an x86 and an x64 machine. On the x86 machine, several assemblies are located in Program Files, and the path of the assemblies are shown as c:Program Files...... When I move this project to the x64 machine, the same assemblies are located in C:Program Files (x86).... Is there a way that I can confugure VS2010 so I don't have to manually change the path when I move the project from one machine to another?
View 1 RepliesWhen I use Project Reference to add dependent assemblies to my C# library project, I can use the "Go To Definition" popup menu item to go to the source file of the class defined in the dependent assembly. That is one of the most useful features of VS for me. However, when I add dependent assemblies as BIN References (via the Browse tab of the Add Reference dialog), I only get the class definition generated from metadata of the dependenat assembly, not the source file.
I realize that intellisense can't find the source directory of the dependent assembly, but where can I enter the directories so intellisense would know? There is a "VC++ Directories" page in the Options->Projects and Solutions dialog, but that is only for C/C++ projects. There should be one for C# as well. The bigger mystery is when I put my project in the debugger, I can step into methods defined in the dependent assembly and see its source file. Why could the debugger find the source file but not intellisense?
when I reference a assembly. It's reference gets added to the project file in my case ( ABC.csproj)
Also when I take a look at the web.config file there is a section called <assemblies>. And lot of assemblies are added there.
What is the difference between link to the assemblies in the Project file and the assemblies in the web.config file?
I have a .txt file and i open this file, read it and encrypt and decrypt it, it works fine. Now i want to read all types of files like .png, .pdf, .doc etc and do encryption /decryption. file.readtoend() does not work here. How can i do tht?

View 1 RepliesI'm working on a project in ASP.Net, and it requires reading/writing to files on my server. I'm hosted at GoDaddy, and they swear they've got me at Medium Trust. When I try to read or write files that are in my own domain, I get Security Exceptions. I've tried multiple ways of opening/saving the files and they all return security errors. Here's the most recent error and offending line of code (I didn't save them all, they're all pretty much the same thing):
Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.MediaPermission, WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' failed.
PngBitmapEncoder pbe = new PngBitmapEncoder();
pbe.Frames.Add(BitmapFrame.Create(new Uri("ornament.png", UriKind.Relative))); <-- Error
I've also gotten the error when trying to read/write using FileStream, Bitmap.Save and new Bitmap("ornament.png"). Could there be a problem with my Web.config? Is read/write supposed to be blocked by medium trust? This is a time-sensitive project and this is a brick wall for me. The deadline is end of business day tomorrow and GoDaddy isn't responding.
One of my NUnit tests has to read in some values from config files. In my main application this process works perfectly well, however when I run the unit test, the code that reads in the values from the config files doesnt read anything in. Ive tried putting app.config in my unit test project (I even tried web.config) but nothing seems to work. Are there any special steps involved when reading from config files in an nunit test ?
View 1 Repliesi've got some problem reading excel files to store into sqlserver database. currently my code has a fileupload control and a button for me to save the excel file into a folder and read the data inside the excel file and write it into the sql database. The code works only if the excel sheet name is Sheet1.xlsx, however i tried upload a diff file named ImportUserFile.xlsx and it gave me the exception below. 'ImportUserFile$' is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long. i have also tried other file names and it seemed only Sheet1.xlsx works.
[Code]....
I know this is probably a pretty easy thing to do and it is if I can upload the file and store it onto the hard drive of the server. What I need to do is read the text file into memory and then parse through it one line at a time. Anyone have any code that demonstrates that?
View 8 RepliesI just need to ask something about .net assemblies. I'm sorry if this question may not be appropriate for this forum but it is very urgent and very important for me to answer so if any kind person can answer in simple and in detail about 'What are assemblies?' I googled about this but I got only one line definition for assemblies rest is only about private ,shared, manifest etc. etc. but I need to know what are assemblies.
View 8 RepliesI have an ASP.NET MVC 2 app targeting .NET 4 that needs to be able to resize images on the fly and write them to the response.I have code that does this and it works. I am using System.Drawing.dll.However, I want to enhance my code so that not only am I resizing the image, but I am dropping it from 24bpp down to 4bit grayscale. I could not, for the life of me, find code on how to do this with System.Drawing.dll.But I did find a bunch of WPF stuff. This is my working/sample code (runs in LinqPad).

In 2005 you need to add a new registry setting in order to see it in the Add Ref dialog box.
BUT
can you add a reference an assemble that are in the GAC in the web.config file?
I get that assemblies store data about an application, and its components. I am still clouded about several vital functions of this very basic concept and cannot for the life of me find a complete all inclusive reference or explanation of this topic. Exactly how far reaching is this within c#.net development? Where is it stored? How is it stored? Exactly what, in it's entirety is in it and how is it used and when? Please, please do me a huge favor. Do not send me on a wild goose chase to some self serving, obscure site with partial explanations that wastes my time. By the time I'm done studying the information within your referenced site or response, I want all of my questions answered.
View 1 RepliesI have an .net assembly build against 3.5 framework. This assembly has a class Foo with two method overrides:
public class Foo {
public T Set<T>(T value);
public T Set<T>(Func<T> getValueFunc);
}
I'm referencing this assembly in my asp.net 2.0 web application to use first override of the Set method (without Func).
But on build I get an error saying that I should reference System.Core to use System.Func delegate... but I'm not using this type...
Is there a workaround to solve this?
PS: There is no option to convert my web application targeting 3.5 framework.
I was trying to go through this tutorial:

but when I tried to add the service reference to the silverlight app, the Add Service Reference window would show me that there was a service file, but the node wouldn't expand to show the rest of the files that contain the services and what not. I got this error instead:
"An error occurred during the processing of a configuration file required to service this request. review the specific error details below and modify your configuration file appropriately."
"Parser Error Message:There is no service behavior named 'AdventureWorks_WebServer.Service1Behavior'."
"Metadata contains a reference that cannot be resolved: 'http://localhost:55579/Service1.svc'.
The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.
If the service is defined in the current solution, try building the solution and adding the service reference again."

View 2 RepliesI'm trying to write some code to use reflection to load new assemblies. I observed the file system with FileSystemWatcher, so that if anything in the folder changed, I can get notified and then reload them.
Firstly I have an assembly filters.dll loaded. Let's say its version is 1.0.0. Then when I have a new one v1.0.1, I paste it into the folder and replace the older one. Of course this fires "Change" event of FileSystemWatcher, and finally lead to assembly reloading.
Everything works fine, but I just want to know, what would happen to the firstly loaded assembly? Get replaced by the newer one? Or still somewhere in the memory?
