Alone form proxy.vb is working without problem, but when I copy it and include to my project I getting always:
Exception:Thrown: "Index and count must refer to a location within the buffer." (System.ArgumentOutOfRangeException)
[code].....
I include 2 exes in my setup project which share dlls. In 2008 this just resulted in warnings when building but I now get an error instead indicating that the file is already included.I can fix this by excluding them but they will reappear after each build so have to be excluded again which slows the process down - example error message is below:
Error 14 Two or more objects have the same target location ('[targetdir]interop.excel.dll') C:DevelopmentPIMSPIMSSetupPIMSSetup.vdproj PIMSSetup
I am reading a file like I always do, created the same way I always do, and EndOfStream never returns True:
Using sr As New StreamReader(filePath)
While Not sr.EndOfStream
'do stuff with Readline
End While
End Using
The only diff is I am using Windows 7. Any Ideas?
The error:QuoteThe CLR has been unable to transition from COM context 0x8683f0 to COM context 0x868560 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.
Following a move away from Desktops and onto Terminal Server machines, I'm having to recompile a number of projects created by my illustrious predecessor at the company.One of these projects is a fairly simple WPF MVVM project, with an error-reporting component added as a referenced project, i.e. the reference is to the project, not to a DLL. Both of the projects were started in earlier versions of Visual studio, but both now target framework 4.0 and are being maintained in VS2010.The whole thing compiles fine, but at runtime I get the following error:
Could not load file or assembly 'companyName.Tracer, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=0156bfd00d8c2368' or one of its dependencies.The located assembly's manifest definition does not match the assembly reference.(Exception from HRESULT: 0x80131040)
The referenced project is signed with a .pfx file, though I have tried compiling with and without the signing, and it appears to make no difference.I'm not sure where "Version 2.0.0.0" is coming from. The referenced project is at version 1.1.* and the main project is also at 1.1.*.Presumably I'm missing something obvious, or I've failed to include some vital piece of information, so I'll try to respond to any requests for additional information as quickly as possible.
I have added an XML file (File.xml) into a project (I can see it in the Solution Explorer), it resides at the root directory level of the project i.e. the same level as the VB program (.vb), the bin directory and the References directory etc..

in which directory is an image copied when you include it in your project?
View 1 RepliesI would like to refer to an image i have added to a project from inside a class of the same project.
View 2 RepliesWhen you add a file that the project will use (in my case an Excel file) and set it to be copied to the output directory, you can of course add a string to a class with the file name in it to use the file. I was wondering though does Visual Studio automatically generate a member somewhere that contains the name of the file? Perhaps in the My Namespace?
Kind of like how when you set the Build Action to Resource, Visual Studio generates a member in the My.Resources namespace for reference. Whenever I change the name of the file in the Solution Explorer it would be nice if I had some method that would automatically update the file name in the code.
Everything was working just fine...then one time running the debugger and I'm given a 401.2 error from IIS Express 7.5. I created a new project and tested - worked fine. I ensured the web.config and other project settings where identical - still getting the error in the original project!

Why does my VB.Net Project disappear instead of giving an error message?This only started happening recently, but when debugging with Visual Studios instead of getting errors, the program just closes as though the stop button was pressed. This doesn't happen for all error types but it consistently happens if there is some sort of casting error. This is an overly simplified example, but the lines below would cause a program to vanish as soon as they run. Dim i As Integer i = "A" One other interesting part of this is that if that was in a try catch block the error would be caught instead of closing the program.I'm in an office setting so I've been able to test a number of configurations and have found that this problem only affects Windows XP PCs, but not Windows 7. And it consistently happens with Visual Studios 2010 Professional and Ultimate, Visual Studios 2008. Besides that we apparently we all need Windows 7.

I was able to include (add) an existing project to a current one. I finally got all the references and libraries in place, and everything works great. I decided to move forward with development and started adding some features...much to my surprise, when I debug none of the controls are there (In the form belonging to the added project)...
Do I need to develop the second project from it's original solution (and not from within the combined solution)?

View 7 RepliesWith Visual Studio - 2008. I publish to my server. I have problem with the ClickOne, I cant find a way to include my DB connection and resources folder included in my project. It update correctly, but it does not include my resource folder a database connection. Maybe something with the rights to connect to the DB. Can can also see that every time I update my application, it make a new folder but it do not input my folders.
Any right way to do this:
Dim con As New OleDbConnection("Provider=Microsoft.jet.oledb.4.0;data source=" & "Resources/" & "myDB.mdb")
This is my string to connect. And I have added "myDB.mdb" it to my resource folder in the project. I have followed this video: [URL]. What is the correct way to implement a DB connection to my project when I am using ClickOnes?
I have some programming background in VB4,VB6, and some assembler, also I was a very big fan on of Qbasic.Programed 100's PIC micro in assembler and basic.
I know this list of experience will put a big smile of many readers face, that's what I have.Trying to learn VB2008 Express, I find everything I know is out of the window, nothing works the way it used to be.Cant find solution for the simplest task, like read/write a file in binary, read/write serial port.I have some e-books to read, all talks about thinks are actualy works and I could figure out myself or other case I cant get around what era they talking about.I'm cursing right now, ho would you teach a old dog for new trick's.English is my second language, not always understand all the terms and other lings what books and online sources use.I have not wrote any code for Windows for at least 5-6 years, but did wrote may program for Micro controllers in Assembler and Basic.
For example I found this code to demonstrate how to create a file, write in binary then read it back.It does not work, cant figure it out why, help is useless, stops at "fs.Position = 0", the function of this line make sense, but why errors out here.Debugger give me "Cannot access a closed file.", I don't see any line closing the file, is everything will be this difficult.Not to mention this is pose to be a working example from a book.This is the way I used to open a file.[code]...
I have no code specifically for this part of my project just saying this ahead of time.I have not used text files that are inside my project but I want to be able to open the file when I load my form and save it when I close my form.I know how to save manualy and same with opening but that defeats the purpose this has to do as much as possible on its own.All I have are code from a project I made a while back which was a notepad program.[code]however I need this to all happen on its own and it needs to install these text files with the program hence why they are in with the project there are about 30 text files that will need to be with it so if I can get help with one then I can figure the rest out.
View 3 RepliesI have the following code
TestArray(0) = "<RD><PS:CL><JL:Jump,""(.*?)"">"
TestArray(1) = "<RD><PS:CL><JL:Jump,""(.*?)"">(B)(.*)"
TestArray(2) = "<RD><PS:CL><JL:Jump,""(.*?)"">(C)(.*)"
Do Until xRead.EndOfStream
'do stuff here here with test array(i)
'do stuff here here with test array(i)
'do stuff here here with test array(i)
'do stuff here here with test array(i)
i = i+1
loop
I would like it so that instead of "Do Until xRead.EndOfStream" I would like to read the file line by line until a match is found, then add +1 to i and repeat.
If I have a .dll, isn't it I can place it in a folder providing that the folder is included in the project? since I really do have a problem during publishing.

Windows.Forms.DataGridViewTextBoxColumn'.C:SoftwareForm1.vb 1425 19..When the line generating the error is this Me.Name = "Form1".where it has the "Form1" portion underlined in blue.This is a weird error because that line was made by the IDE to say the name of the form and has nothing to do with 'System.Windows.Forms.DataGridViewTextBoxColumn'.I tried saving my progress and restarting the IDE with no luck..Now I cannot even access the form in designer mode,One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes.The designer cannot process the code at line 1424: Me.Name = "Form1" The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified.
View 5 RepliesI have a program that writes unhandled exception detail to a log file stored in the same directory as the program itself. I am wondering how I can have keep the file in the same location, and not have to worry about a file write access. With Vistas User Access Control enabled, the file is not accessible unless the program is run as an administrator, which I don't need it to be for anything else. The file does not exist all of the time, it only exists after an error occurs. Users are encouraged to email the file to me and then delete the file. Thus the file should only exist if their is a error that the user has not emailed. I really want to keep it in the same directory as the program itself, or within a subdirectory of the programs directory, since the portable version is exactly the same program executable and I would like to keep it that way. I am not sure how to go about setting the file security, set it when I create the file if the file doesn't exist, prompting for Administrator privileges to create it with the security. I was also thinking that I could just set the entire folder containing the program executable when it is installed, and then it would be able to create the file without having to have administrator privileges.
