VS 2010 Error Opening Design View - vb.net

There is no editor available for 'file path here'. Make sure the application for file type (.vb) is installed.
This is the error that I get when I try to open a project I did a while back in VB. I tried a C# project and I can open the form for viewing fine, but for some reason VB won't work? Any ideas? I really don't want to do a repair on the whole application as it takes a while and I'm not even sure I have the ISO right now.

Check the compile mode of the object. If it is not set to "compile" then VS gets a bit weird about opening it up.

Values cannot be null. (Parameter 'baseName')

When trying to open the form deisgn it says values cannot be null. (Parameter 'baseName'). I still can run the system without error. Dont know how to fix it and have to change some gui design. Help me its for my school tnx
I had this problem this morning and a few hours later I decided to just start over and copy the code from the old project to the new empty project. Everything is working in the new copy of the project. I copied from old to new by drag-n-drop. I copied all the UserControls before I copied anything that uses them, and built, then copied over the remaining things, and went through all the errors caused by the change in name of the top-level Namespace.
(All of the Namespace errors were in the .Designer.vb files. I have posted elsewhere "never edit those files by hand unless you know what you are doing." This case was one of the rare exceptions.)
I had the OP's problem that when I tried to open a Form in the designer, I got the message
Value cannot be null. (Parameter 'baseName')
It didn't matter if I tried to open the Form in Solution Explorer or by pressing Shift-F7 in the Form's code window. However, sometimes Shift-F7 resulted in a wait cursor followed by silence - no error message.
Like the OP, the project did run without errors (well, same bugs as before but you know what I mean).
Another symptom: If I launched VS and tried to open the Form designer before Intellisense was initialized, instead of the other error, the window that should show the layout of the Form showed this instead:
File path: full path of the file I was trying to open
Frame GUID: 2c01570-c72c-11d0-88c3-00ac0c9110049
Frame mode: VSFM_MdiChild
Error code: 0x80131500
There are no MDI containers in my project. It's a reference to VS 2019.
The same error occurred in every Form and UserControl in the project.
The same error occurred in any new Form or UserControl that I added to the project.
The error did NOT OCCUR in any and all other projects built in VS 2019 with a target of .Net 5.0
The error DID OCCUR with the same project on another machine running a clean install of a later version of VS 2019.
Attempts to Clean Solution or Clean Project failed, with a generic error message, it was something like "Clean Project failed."
Nothing about these problems appeared in any event logs.
Every time the problem happened, when I shut VS, one process was left running (per TM).
Here are some other things I did to try to suss it:
Ran a repair install on VS 2019 and reboot.
Opened each and every VS-generated file in another project and compared them line-for-line (most are text) against the corresponding files in the broken project. No data-independent differences.
Searched exhaustively with 3 search engines and many terms for someone else that posted about this error. This is the only post I found.
Deleted, renamed, or moved files that are automatically generated by VS, including some Json files, XMLs, and caches.
What I did not try:
Roll back the code to the most recent commit.
Uninstall VS 2019 completely, reboot, install VS 2019 as if an initial installation.
Just had the same experience. I took me a while before I got everything to work again, but the clue in my case was that I had added a new item to my project, and for some reason I had managed to delete the file name in the process so the only thing left was 3 new files with only the extensions .resx, .cs and .Designer.cs
I quickly deleted the ".cs" file but forgot the rest.
Suddenly I was unable to open my main form in the designer - and the “Value cannot be null. (Parameter 'baseName')” started to appear. It was only affecting my main form.
I tried almost everything described above except the reinstalling part.
But then I deleted ".Designer.cs" and ".resx" from within visual studio (Solution Explorer), and then the problem went away.
I started getting this error after using a hack to support generics forms (e.g. MyForm). The designer generated a file:
MyForm.resx
which worked for design time (even with the form being generic) but crashed at runtime. My hack was to rename the .resx file:
MyForm`1.resx
However that is when the Designer stopped working. It stopped working for ALL forms/user controls in entire solution (not just the generic I was experimenting with). I assume there is some kind of process that crawls all the resx files whenever you open any Designer and that is the source of the Exception.
I was able to work around the issue by:
Renaming the resx back to its non generic title (i.e. MyForm.resx)
Restarting visual studio.

Can only compile a VB6 DLL after opening a specific form in design mode

ActiveX DLL project - running it or Menu > File > Generate Dllname.dll... both produce the error message: Error loading DLL
However, if I open a specific form in design mode then I can compile or run the project without problem.
The form has a MSCAL.OCX v11 Calendar inside.
Note that if I open any other object (classes, forms, etc) continue with the error when try to Run/Compile. Is mandatory to open the frmDate.frm object if I want to Run/Compile the project.
I don't understand why it has this strange behavior and if there is a way to solve it.
Do you have proper appointed the startaup point of the project?
You can do this using this path above:
Go to “Project”->” Properties “, and in the “General” tab select the appropriate form from the “Startup Object” list box.

Debug Design Mode in Visual Studio not breaking

So I am currently unable to open a Form and get the following error:
System.ComponenetModel.Design.ExceptionCollection was thrown.
or:
The designer loader did not provide a root component and has not indicated why
Usually the way to solve this is to open another instance of Visual Studio with the same project, attach the debugger to the other Visual Studio and try to open the form.
However, that does not seem to be working. The debugger does not break when the error is hit, and attempting to 'Break All' at any other point does not show me the source code and just the screen saying:
Your app has entered a break state, but there is no code because all threads were executing external code (typically system or framework code).
Attempting to put break points also results in:
The breakpoint will not currently be hit. No symbols have been loaded for this document
Am I missing a setting? Incorrect Setup?
I have been battling this for half a day and thoroughly search the interwebs with no luck thus far. My designer is also fairly complex and lengthy which means trial and error is an absolute last ditch option.
First attempt to resolve:
you may have tried it already. Right click the Solution in solution explorer, click "clean solution", this deletes all the compiled and temporary files associated with a solution.
Do a rebuild of the solution and try to debug again.
Second attept to resolve:
Start debugging, as soon as you've arrived at a breakpoint or used
Debug > Break All, use Debug > Windows > Modules. You'll see a list of all the assemblies that are loaded into the process. Locate the one you want to get debug info for. Right-click it and select Symbol Load Information. You'll get a dialog that lists all the directories where it looked for the .pdb file for the assembly. Verify that list against the actual .pdb location. Make sure it doesn't find an old one.
In normal projects, the assembly and its .pdb file should always have been copied by the IDE into the same folder as your .exe. The bin\Debug folder of your project. Make sure you remove one from the GAC if you've been playing with it.
third attept to resolve:
Disable the "Just My Code" option in the Debug/General settings.
there are might be other causes to your problem, i picked them from here. you may try other solution to try resolve your issues. Fixing "The breakpoint will not currently be hit. No symbols have been loaded for this document."

Changes in the code or the designer won't update when debugging

I am trying to debug my VB.net app in Visual Studio Express 2010, when I realized my changes will not update on my form-on the designer or in the code. After looking online, I found that you should clear out the "Debug" folder under the bin. That worked-for only one time. Now it went back to the older version and when I delete it again, it doesn't change. When I build the project and run it from the "Release" folder, it works perfectly, but when a error occurs at runtime, it won't show where the error is because it is running independently.
Thanks in advance.
(I have Windows XP SP3)
I had the same problem. Frustrating problem....? Close the project, go to debug bin/folder, delete these files, reopen project and rebuild it (F5).
- .exe
- .pdb
- .vshost.exe
- .vshost.exe.manifest
- .xml
it works 99.99%.......thanks
Before I'd create a new project, I'd copy all of the code-behind (including the code that creates the controls that you're not supposed to touch) into another form. That may be all you need to do. Try compiling that form and running it and see if it's good. If so, you won't have to create a whole new project and can just delete the old form.
I would think there's something causing this that would be much easier to to fix. Are there any config files or anything like that? Are you building to the right location?
It's been a while since I've done winforms, but I remember this happening in VS 2005 and I just created a new form and copied the code-behind into another winform and compiled.
Hope this helps.
mmm... if it was for me, with such a weird bug, i would create a new project then insert the files (not as a link, but a copy) in the project, and i most likely all will work fine after... Faster than finding where-the-hell is that wrong parameter...
So how do you do that ? Well create a new project, choose the folder and name, change namespace in settings if needed, then in project explorer Add existing item, then Browse and select your code and xaml (and other maybe) files. Let us know.
This happened to me as well. I believe the /bin and /obj folders of my application must've been locked for by some other application. Before manually deleting them I tried running Visual Studio as an administrator and did a Clean and a Rebuild which worked. If it doesn't work for you, try deleting the folders manually.
Close VS
Press Ctrl + Alt + Delete
Choose "Task Manager"
In the "Process" tab in "Task Manager" find your "ProjectName.EXE" and click "End Task"
Restart VS
I have the same problem, but i changed the solution config next to the start button from debug to release and that fixed my problem, try it :)
"Save all" works for me in VS 2010 VB, in Debug and Release mode.
I put the "Save all" icon next to the Run and Build icons.
First make sure your Localizable Property of you form is set to FALSE

Windows XP Excel VBA Crashes on Windows 7

I am trying to switch a Excel VBA macro from Windows XP to Windows 7. Both of the Windows versions are 32-bit operating systems. My Windows 7 version is Enterprise edition.
The VBA code works fine on Windows XP. When I have tried to run the code on Windows 7, it crashes and reports no error description.
I have registered msinet.ocx, which appears to be required for Microsoft Internet Transfer Control 6.0. I have also tried to fix security issues by adding the additional com components tabctl32, comctl332/232/32 and comdlg32, all of which are ocx files. However, nothing changes - my code still fails on Windows 7.
Once msinet was unregistered, Excel VBA opens my Workbook, reports the missing reference msinet and does not work at all. How do I resolve this issue?
Awkward. Open the sheet in an Excel session with Macro Security set to high or medium, and reply 'No' to the dialogue about enabling VBA macros in the sheet.
If it opens, you should still be able to view the project, and this might show an obvious missing reference or an error if you attempt to compile it.
Next: save the workbook as html and close Excel. Clear the temp folder, restart excel, open the html file and save it back into Excel format. If you're lucky, all the legacy objects and references will be cleared out and replaced by versions compatible with your new OS.
This works about half the time.
The system not crashing when msinet.ocx is not registered doesnt necessary means that it is the problem.
If you have a call to that library (msinet.ocx) in any procedure inside of or called from the ThisWorkbook module and you have that library unregistered, then when the file opens and tries to run the On open macro the module will not compile and therefore wont run the line of code that makes it crash. (I am only guessing that this might be your case.)
Try to find out which exact call makes your system crash.
Let msinet.ocx registered.
Open the file without activating the macros.
Then manually run Step by Step (F8) through the opening code of your file ( Private Sub Workbook_Open() )
Eventually you will reach the exact line of code that makes your system crash. Whit that information you will be able to get more help.
NOTE:
To open the file without activating the macros you can use one of the following methods:
Press and keep pressed the Shift key after you doubleclicked on the file to open it(from the windows explorer). For this method to work, the Excel application must be clossed.
If the Excel application is open, then go to the VB editor and type application.EnableEvents=False in the immediate window (and press enter to run it). Just be aware that this will disable the events on every file in that instance of Excel. You will have to set it back to true or close the application (not just the file).
Check if you don't have references to missing libraries, if so simply uncheck it. I had a similar problem and it helped in my case.
