• Project reference vs. DLL Reference - Which is better?

  - by Zannjaminderson

  I know there are other questions regarding this subject, and I've looked at this question, but I'd like to see a little bit more discussion and information on both sides of this - is it a better practice to add a project to a solution and reference the project, or to add a reference to the .dll?

• Can someone answer this for me?

  - by Dcurvez

  okay I am totally stuck. I have been getting some help off and on throughout this project and am anxious to get this problem solved so I can continue on with the rest of this project. I have a gridview that is set to save to a file, and has the option to import into excel. I keep getting an error of this: Invalid cast exception was unhandled. At least one element in the source array could not be cast down to the destination array type. Can anyone tell me in layman easy to understand what this error is speaking of? This is the code I am trying to use: Dim fileName As String = "" Dim dlgSave As New SaveFileDialog dlgSave.Filter = "Text files (*.txt)|*.txt|CSV Files (*.csv)|*.csv" dlgSave.AddExtension = True dlgSave.DefaultExt = "txt" If dlgSave.ShowDialog = Windows.Forms.DialogResult.OK Then fileName = dlgSave.FileName SaveToFile(fileName) End If End Sub Private Sub SaveToFile(ByVal fileName As String) If DataGridView1.RowCount > 0 AndAlso DataGridView1.Rows(0).Cells(0) IsNot Nothing Then Dim stream As New System.IO.FileStream(fileName, IO.FileMode.Append, IO.FileAccess.Write) Dim sw As New System.IO.StreamWriter(stream) For Each row As DataGridViewRow In DataGridView1.Rows Dim arrLine(9) As String Dim line As String **row.Cells.CopyTo(arrLine, 0)** line = arrLine(0) line &= ";" & arrLine(1) line &= ";" & arrLine(2) line &= ";" & arrLine(3) line &= ";" & arrLine(4) line &= ";" & arrLine(5) line &= ";" & arrLine(6) line &= ";" & arrLine(7) line &= ";" & arrLine(8) sw.WriteLine(line) Next sw.Flush() sw.Close() End If I bolded the line where it shows in debug, and I really dont see what all the fuss is about LOL

• Problem monitoring directory for file activity in VB.net 2010...

  - by Mike Cialowicz

  I'm trying to write a simple program to monitor a folder for new files in VB.NET 2010, and am having some trouble. Here's a simplified version of what my program looks like: Imports System.IO Public Class Main Public fileWatcher As FileSystemWatcher Sub btnGo_Click(sender As System.Object, e As System.EventArgs) Handles btnGo.Click '//# initialize my FileSystemWatcher to monitor a particular directory for new files fileWatcher = New FileSystemWatcher() fileWatcher.Path = thisIsAValidPath.ToString() fileWatcher.NotifyFilter = NotifyFilters.FileName AddHandler fileWatcher.Created, AddressOf fileCreated fileWatcher.EnableRaisingEvents = True End Sub Private Sub fileCreated(sender As Object, e As FileSystemEventArgs) '//# program does not exit when I comment the line below out txtLatestAddedFilePath.Text = e.FullPath '//# e.FullPath is valid when I set a breakpoint here, but when I step into the next line, the program abruptly halts with no error code that I can see End Sub End Class As you can see, I have a button which will initialize a FileSystemWatcher when clicked. The initialization works, and when I place a new file in the monitored directory, the program reaches the fileCreated sub. I can even see that e.FullPath is set correctly. However, it exits abruptly right after that with no error code (none that I can see, anyways). If I comment everything in the fileCreated sub out, the program continues running as expected. Any ideas as to why it's dying on me? Any help would be greatly appreciated. I'm fairly new to VS/VB.NET, so maybe I'm just making a silly mistake. Thanks!

• Debug.Assert Appears in Release Mode

  - by Ngu Soon Hui

  We all know that Debug.Assert will not be compiled into the dlls when compiled in release mode. But for some reason Debug.Assert did appear in the release version of a component I wrote. I suspect that I might have mess up my csproject setting. Any idea why Debug.Assert appears in release mode? P/S: I have double checked to make sure that I was really compiling in release mode before asking this question.

• What is your most obfuscated JavaScript example (5 lines maximum)?

  - by snowlord

  JavaScript is known as a language with many weird features. This probably makes it a good language to write extremely obfuscated and hard to understand code in (in the style of The International Obfuscated C Code Contest). What would be your best example of obfuscated JavaScript code (5 lines maximum)? I am thinking that it should be very hard to understand, but also have an element of style or humor in it. And for clarity: using obfuscation tools is not the point, of course. Hand crafting only!

• Switching between multiple reports (.rdlc) in a single report viewer

  - by UserNameHere

  I have 2 reports, "report1.rdlc" and "report2.rdlc" and I want to be able to swap betweent the 2 of them in a single report viewer ("rv_1"). I also have 3 buttons: btn_1 which does: rv_1.LocalReport.ReportEmbeddedResource = "Application1.Report1.rdlc" rv_1.RefreshReport() btn_2 which does: rv_1.LocalReport.ReportEmbeddedResource = "Application1.Report2.rdlc" rv_1.RefreshReport() btn_3 which does: dim rds as new ReportDataSource rds.name = rds.value = rv_1.reset() rv_1.LocalReport.DataSources.add(rds) rv_1.RefreshReport() Now no matter what I put for rds.name and rds.value it leaves me with "A data source instance has not been supplied for the data source 'dataSetName_TableName'. So my question is; what do I need to put there in order to get this to work correctly?

• Satisfying indirect references at runtime.

  - by automatic

  I'm using C# and VS2010. I have a dll that I reference in my project (as a dll reference not a project reference). That dll (a.dll) references another dll that my project doesn't directly use, let's call it b.dll. None of these are in the GAC. My project compiles fine, but when I run it I get an exception that b.dll can't be found. It's not being copied to the bin directory when my project is compiled. What is the best way to get b.dll into the bin directory so that it can be found at run time. I've thought of four options. Use a post compile step to copy b.dll to the bin directory Add b.dll to my project (as a file) and specify copy to output directory if newer Add b.dll as a dll reference to my project. Use ILMerge to combine b.dll with a.dll I don't like 3 at all because it makes b.dll visible to my project, the other two seem like hacks. Am I missing other solutions? Which is the "right" way? Would a dependency injection framework be able to resolve and load b.dll?

• Dynamic External Program in debug tab vs2008

  - by Justin Holbrook

  I am playing with NServiceBus using the generic host; specifically I'm working on having 2 different configurations, a debug configuration that logs to the console and a release version that logs to metabase (I'm using VS2008). I had just made some code changes (commented out a logging statement), but it was still showing in the log when I ran my solution. I eventually figured out that I had switched configuration to release, made my change, then built. I think the change isn’t being picked up because in the debug tab of my project properties I have the following (abbreviated) path to the generic host: C:...\Inventory\bin\Debug\NServiceBus.Host.exe Notice it specifically points to the debug directory. So basically even though I’m in release config it’s firing up the host in the debug directory which I think is then using the dll's in the debug directory (which is why my changes didn't get picked up). I tried to come up with a workaround, but have been unsuccessful. VS Macros (like $(Configuration)) and relative pathing are not allowed here. http://connect.microsoft.com/VisualStudio/feedback/details/422223/relative-path-not-allowed-in-c-project-debug-properties-window Any ideas? I hope this doesn’t require a custom build task.

• How to find which existing .NET solutions contain a certain project?

  - by Daniel Daranas

  I am exploring a structure of folders with C# projects such as the following: Projects ProjectA ProjectB ProjectC ProjectD Scattered around in the same folders as the .csproj files, there are several solution (.sln) files. Is there a fast way to find all the solutions that contain ProjectD.csproj? I can open them one by one and see what they contain, but I would like a feature such as "find all the solutions containing this project".

• EXE stops working if containing folder is renamed. MSVCP90.dll

  - by John

  This popup comes up as soon as the app is started: The program can't start because MSVCP90.dll is missing from your computer. Before anyone says "install the VC++ runtimes", wait! If I rename the folder containing my .EXE then the app runs. If I rename it back, it breaks. The app has been running for weeks without any changes to my system/VS installation (2008 SP1), we suddenly spotted this error a few days ago. Lost as to why the name of the dir is causing issues... again this has not changed in months and all our resource paths are relative anyway, e.g "../someOtherDir/...." It doesn't just do this on my PC, we have the /bin dir (the one containing EXE) in SVN and suddenly everyone started seeing the same issue, even though the binaries themselves seem just fine. Is it possible some additional data got put into SVN and that's the cause? Since it's not just one PC, there must be something either in SVN or the EXE itself... Note this popup comes before our code even gets to run.

• Compiling 32-bit Program on VS 2008

  - by gordonwd

  I've been developing on VC++ 2003 on an XP PC but am now on Windows 7 and bought a cheap legal copy of VS 2008 to continue work on the same project. My product has to continue to run on customers' XP systems, so I'm strictly interested in a 32-bit executable. The first issue I ran into was the PRJ0003 error "spawning cl.exe". I had to add the path to this file to the VC++ Directories settings (it appears in both a bin\amd64 and bin\x86_amd64 directory, but I don't think it matters output-wise which I use?). The issue I now have (not counting a tedious cleanup to convert strcpy to strcpy_s, etc.) is that I'm not clear on whether I'm generating a 32-bit or 64-bit exe out of this. My project properties are set to a target of "Win32", so I assume that all is well. Is this correct? I have read some discussions about this, but it's never quite clear if they are talking about whether the compiler itself is running x64 vs. x86, or whether the compiled code is x64 vs. x86, and how this is differentiated. So am I doing the right thing to generate a 32-bit, Win32, x-86 program?

• Windows service: Listening on socket while running as LocalSystem

  - by Socob

  I'm writing a small server-like program in C for Windows (using MinGW/GCC, testing on Windows 7) which is eventually supposed to run as a service with the LocalSystem account. I am creating a socket, and using Windows Sockets bind(), listen() and accept() to listen for incoming connections. If I run the application from the command line (i.e. not as a service, but as a normal user), I have no problems connecting to it from external IPs. However, if I run the program as a service with the LocalSystem account, I can only connect to the service from my own PC, either with 127.0.0.1 or my local address, 192.168.1.80 (I'm behind a router in a small local network). Neither external IPs nor other PCs in the same local network, using my local address, can connect now, even though there were no problems without running as a service. Now, I've heard that networking is handled differently or even not accessible (?) when running as LocalSystem or LocalService or that services cannot access both the desktop and the network (note: my service is not interactive) at the same time due to security considerations. Essentially, I need to find out what's going wrong/how to listen for connections in a service. Is running as NetworkService the same as running as LocalSystem, but with network access? Surely there must be servers that can run as background services, so how do they do it?

• How to pass sockets created to another Java Process

  - by whoi

  Hi; We have an application which creates many sockets which belongs to its thread, By design if this application somehow fails, all threads stop which is not wanted. So to overcome this issue, each thread must be separated from the main application, if one of the threads fails, the other ones should be running. One thing in our mind is to pass created socket to another java process, so what is the correct way? An other approach also is welcome? Waiting for your suggestions...
