IDE :: Error When Changing "app.config" Build Action
Apr 20, 2011
recently i have been working on a desktop project, and i made couple of changes to the project, one of them was changing the build action for the App.config to "Embedded Resource" by mistake! after that i built the application and no compile errors were shown, so i tried to run it but the following run time error showed up:
{"An error occurred creating the form. See Exception.InnerException for details. The error is: The URL cannot be empty. Parameter name: url"}
but it did not specify more information about the exact cause or the exact error place. so it will leave you in a miss!
for awhile, i did not know what was the cause of this due to the numerous changes i did, so i started to review my latest changes one by one till i discovered that changing the build action for the App.config file was the reason for this error.
i made a class library with by adding two .jpeg images and changing build action property to embeded resources and i saved i want to use this two images from this .dll into my application .
I've copied the files albanyc.ttf and MTCORSVA.TTF into 'Resources' and set the 'Build Action' for both to 'Resource'. A label is set to one or other of these fonts dependent upon what is being displayed. This works fine on this PC but when I copy the program to my laptop it seems to me that neither font is used and the same 'other font' is used in stead of either of the ones I want to use. I tried setting the build action to 'Embedded Resource' but that made no difference and I got an error message when I tried 'Compile' (I kinda expected that, but thought it worth a try). Both CP and laptop have the same OS, Win.7 64bit, the only difference is that the PC has Pro. and the laptop Home P.
I have a solution with several projects and several developers, each with their ownenvironment (of course). To manage connection strings between each environment, I have created several app.config files for each environment: app.config.dev, app.config.qa, etcThe pre-build event simply copies the app.config.$(ConfigurationName) to app.config. This pre-build event is done for each project in the solution, and the connection string is included in each (including the test project).
I am trying to build custom configuration section in my app.config file. I am using the following as my example: [URL]. According to this article, I am supposed to inherit from the ConfigurationSection class, add the desired section to my app.config file, and then specify a "configSections" declaration in the app.config file to identify the section and the class that should process it. My problem is that I cannot get the class loader to load my class for processing the section.
If I follow the example and set up my "configSections" as: <configSections> <section name="MyStuff.Configuration" type="MyStuff.MyConfigurer" allowLocation="true" allowDefinition="Everywhere" /> </configSections>
I get the following error: Could not load type 'MyStuff.MyConfigurer' from assembly 'System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
I think the error is telling me it can't load my class from the System.Configuration DLL and that makes sense; the class is in my application code. So how do I tell it to look in my application code to find the class? Do I have to put my class in its own DLL to get this to work? As an alternative approach, is there some way I can just find the section in the application configuration and process the XML myself? The app.config file is the ideal location for this information. Also, this would be easier for me than going through all of these contortions to do what should be a relatively easy operation.
I'm using app.config to store database connection strings.My question is. Is it possible to manual change configuration file on the user's computer after installing msi file. for example if I decide to change to the dev database vs live.
For example i have form within the application which shows the connection string in a text box so the user can change it to there database but i cant work out how to save the new string to the connection string within the app.config file
How do we overwrite config file at runtime. I have four config files for DEV, TEST, UAT, PROD. Based on user selection I need to overwrite the default config file completely with one of the selection specific config files. These config files not only have appsettings section, but also has complex cutom sections and subelements with lot of attributes. I need to overwrite and refreshsections dynamically at runtime. I know there are so many articles on editing appsettings sections. But I want to completely overwrite the entire file.
I have this VB.Net 1.1 project that I have to make some changes to. There is a flag in the App.config file. If it is false, the page just loads a splash screen and runs the program normally. If it is true it first opens a login window. VB.Net is not something I've ever worked with before. I can't for the life of me figure out where the logic for the picking the startup object is. In the property pages, Main.vb is always set as the startup object, but that's not even the window that loads up when the flag is false, it always comes after the splash screen.
I have a web.config file on my computer.There are alot of things i need to change and add in the file. (I am actually working with my SharePoint web.config file)Can i do this with a Batch file, if so how would i do it. Or how would i do it using VB.NET or C# code? Edit: i need to create a program to alter a web.config of lets say i web.config laying on my deskop and not the actual web.config of my project
I changed config file of the windows many times. Before changing config file I stopped the service and after changing config file, started again. Every thing worked fine.
But last time when I made some changes in config file of the windows service and started it - It didnt worked, I even tried reinstalling the service but in vain.
As a last resort I rebuild the service with new config file and copied newly build files on the server and installed the service. To my surprise the Windows service worked perfectly this time.But I have only made changes to config file and the code of the windows service was untouched. My question is, do we need to rebuild the Window service if we change the config file many time?
From my DLL project I have succeded in making AutoCAD launch by pressing F5 from VB.net IDE (Visual Studio 2008) en route to try to make debugging of the DLL easier ...
... however one last obstacle is currently in the way and the obstacle is that for some reason when I hit F5 and AutoCAD is launched my breakpoints are not recognized at all... and program runs from start to finish instead of allowing me to debug ...
It issues a strange message which says "The following module was built either with optimizations enabled or without debug information... to debug this module, change its project build configuration to Debug mode..." and it is all weird because as far as I know I am not in release mode .. but in debug mode (anyhow I am relatively new to Visual Studio .NET so I am thinking that my impression could be that I am in debug mode when in actuality I maybe in release mode)...
Here is why I think I am debug mode ...
1. From Solution explorer ... when I click on the Solution Name and view its properties ... the Active config property says Debug|Any CPU
2. When I look at the properties of the project and look at the compile tab it says that the Configuration is Active (Debug) and under Platform it says Active (Any CPU).
3. Under the Advanced Compile Options of Compile Tab from project properties ... Enable optimizations is UNchecked ...
Anyhow with all the settings mentioned above it seems that I have everything okay but then the message above proves otherwise ... and so at this point I know that I am still missing something ... like a setting somewhere... wondering what else do you think am I still missing?
As additional info...there are seven projects in the solution and it is the main one (the one that I set as startup project) whose properties I refer to in all the paragraphs above.
I'm programming in VB using Visual Studio 2005 Professional. I have a code munger perl script that generates some of the *.vb files that I want to compile. The script and the associated files are in my project directory, and when I run the script from the OS command prompt, it writes the files in the same directory, which is what I want. Rather than do this, I want to invoke the perl script as a pre-build event. I've gotten it to work ... almost. The only issue now is that the files are now deposited in TargetDir (/bin/Release e.g.) instead of ProjectDir. I could just change TargetDir to be ProjectDir, but that seems like I'm asking for trouble. Is there a way to separately specify the target directory for pre-build commands? Or change it to ProjectDir, then change it back after I'm done with the pre-build?
I imported a website made in visual studio express 2008 to visual studio express 2010. When I run the home page I get the following error:"It is an error to use a section registered asallowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS."
a datacontext defined in a module(domain services ado.net ria)a page having add/delete methods whenever any method is executed, it is found that all the previous actions (NEW RECORD ADDITION and DELETION OF RECORDS) are carried out before the new action is carried out normally
this behaviour is not prominent but "when using break points and inspecting the values of the variables and table object to be added to context, it is clear that all the previous actions take place again. even when the datacotext. savechanges is called, even after that still all actions carried out on the datacontext repeat themseleves, when any new action is to be carried out
The following code produces a sound that's like a tone or a soft bell, indicating that an action has completed successfully: System.Media.SystemSounds.Beep.Play() Any code for the opposite? You know like if you tried to do something in Windows that was invalid. Is there some kind of default sound indicating an error that I can invoke on a Windows computer in VB.Net similar to the one above only discordant?
When having hundreds of .rtf files in an app, is it best (and Quickest) to set the "Build Action" as "Content", "Resources" or another property setting?

I just found out that I have a bigger problem than i thought.. anyway.. it's with my app.config. It started with my main program that im almost done with but now its acting up and now it's everything.
I am trying to encryp web.confif using RsaProtectedConfigurationProvider.Everything works fine on my machine which is Windows XP. I know I am supposed to use "ASPNET" in following command for XP. My test server is WIndows server 2007 and following command gives me an error. "No mapping between account name and security IDs was done." I know ASPNET is not the default application pool on the server. What command should I use on the server?
