I am having another issue with WMP in VB.NET 2010.I wrote an app using WMP in VB.NET 2010, using .NET Framework 4.0 of course, but had to change the framework target to 3.5. After doing this, the WMP component does not work. How, if I even can, fix this problem so that the program will run on .NET Framework 3.5? The error says that it could not load AxInterop.WMPLib.dll because it was built in a runtime newer than the currently loaded one.
I have a Form with a Media Player in it. Which plays a Song.
[Code]...
It's playing in the background since the Form is hidden. When I play itin Debug, everything works fine. When I run the app outside Debug, I get this error: [URL] The Music File is there, but strangely, there comes this weird error.
I am using Windows Media Player library (WMPLib.dll) in my application. I wanted to make CD Burning wizard, because WMPLib.dll has ability to burn audio/data CD's. I declared an object which can erase or burn CD:
Dim CDBurner As WMPLib.IWMPCdromBurn
Dim WMP As New WMPLib.WindowsMediaPlayer()
[CODE]...
I get exception with message "Attempted to read or write protected memory.". I have an option "Full Trust Application" enabled in Visual Sudio. Is there anything I can do about this error?
I'm trying to make a simple equalizer I have my windows media control and a trackbar, this is the code im using.
Private Sub TBGLevel_Scroll(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TBGLevel.Scroll Dim equalizer As WMPLib.IWMPEqualizerSettingsCtrl equalizer.gainLevel1 = TBGLevel.Value End Sub
Upon moving the trackbar I get this error
NullReferenceException was unhandled Object reference not set to an instance of an object.
I also tried
Public equalizer As WMPLib.IWMPEqualizerSettingsCtrl
Same error occured.Basically i hit play so it would go through my playlist on the form then attempted to move that gainlevel and it produced the error.
I am using Windows 7 64-bit and Visual Studio 2010 (VB.Net)
I am trying to write a media player using the wmplib.dll for playback. Everything is working but I found a one problem I can't find an answer to. How do you find the songs duration before actually playing the song? the code I am using is below. I get an error when I try to update the slider with the current position. The messagebox returns all zeros. (i.e. 0 - 0 -0 ).
' SET FILE NAME Dim sFile As String = "D:MusicSongsArtistsEaston Corbin�1-Easton Corbin�4 - The Way Love Looks.mp3"
Hmmmm having discovered that using the mciAPI doesn't utilise 5.1 sound, but using a virtual WMP does - I started a new approach to my multimedia project using some code from the net. BUT I keep getting exceptions (particularly with type casting). In the subrountine 'Player_PlayStateChange'.
The listing (see below) is now well commented by me. Can anybody please help concerning the damn annoying exceptions and stop me pulling my hair out.
The MSDN documentation for WMPLIB states that syncing to device is not supported in .NET programming, only C++.Is there, however, a simple wrapper class or DLL that can be used to interface between a .NET program and the nescessary C++ code?Or is there a better way to sync files to a device using VB.NET? Are all devices suited/compatible with just a simple filesystem.copyfile ?
I need to get the current song in Windows Media Player, preferably using the wmp.dll library. There's documentation on MSDN [URL] but none of the resources I've tried have worked, even though I referenced the DLL and imported. Note that I'm using Visual Basic 2010 Express
When I iterate the media items in a Windows Media Player playlist and set the properties of a user-defined class to the attributes of a media item, the first n rows of the playlist are populated with useful information; however, the remaining rows are empty. If I perform the same operation but access the media items directly (e.g., display the attributes to the console window) then all items in the playlist are populated properly.
Here is an example of the output showing the condition:
Inserting song "The Arrest" from album "Jesus Christ Superstar [MCA Original Cast Recording] Disc 2" into database... Inserting song "Peter's Denial" from album "Jesus Christ Superstar [MCA Original Cast Recording] Disc 2" into database... Inserting song "Pilate and Christ" from album "Jesus Christ Superstar [MCA Original Cast Recording] Disc 2" into database...
I am using a 3rd part dll file (SolidWorks EModelView.dll, COM file) that has a version of 9.2.0.128. When I add it to the resources for the application, however, the AxInteropEModelView.DLL and InteropEModelView.DLL references show a version of 9.0.0.0. When I install the application on a client machine and try to run it, the application says it cannot find AxInteropEModelView.DLL version 9.2.0.128!
im getting an error in my compiled and deployed program that i dont get in the VB IDE that says
The error is: Could not load file or assembly 'AxInterop.zkemkeeper, Version=6.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified. ---> System.IO.FileNotFoundException: Could not load file or assembly 'AxInterop.zkemkeeper, Version=6.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
i have included a reference to the zkemkeeper.dll, and my setup program ships & deploys a few other files that zkemkeeper.dll needs in the application folder what really bugs me is that in the IDE my code works perfect but in the deployed run-time i get this error.
I have recently upgraded an VB6 project to vs2008. I was almost finished when the following error occured. Unable to emit assembly: Referenced assembly AxInterop.MSFlexGridLib does not have a strong name Prior to this error appering, I tested my app several times and it was fine. Only after publishing it did the error appear. I have tried all solutions I could find, but nothing helps. I have read [URL]
This might be a bit of stupid question but I need some clarification. I'm somewhat new to .NET and have created a EXE that had to reference an existing COM DLL. In doing so, Visual Studio 2010 automatically created an "Interop" DLL that it needs/uses to work with the legacy COM DLL.
I have deployed my project and included this Interop DLL with it (in the same folder) and everything is working fine. However, I have other applications that will need to use this same legacy COM DLL. Is it okay to reference it they same way in each application and keep deploying the "Interop" DLL with each application? Unfortuantely, all of these small applications go in the same folder and each use the same Interop DLL (so it will already exist there if it's used by another app.) I'm forced to having them in the same folder because these applications are being called as a way of customizing a parent application. As such it only looks in it's local folder when it wants to run a "custom" app. I'm just concerned if one the EXE's is ever removed and they take out the Interop DLL, then the others that still depend on it will fail.
So, I was wondering if it is possible or a good idea to put that Interop DLL in the GAC? I went ahead and installed the Interop DLL into the GAC and then removed the Interop DLL from the folder where my EXE runs and it failed to work. I get an error that says "Could not load file or assembly". I'm stuck on getting this working.
Do I need to reference the Interop DLL in my project differently such that it's now from the GAC? or Do I need to add something to my .NET code like Assembly.Load to make it work? Do I need to create that Interop DLL myself using TLBIMP?

I am using Interop to read and write to excel but I'm having some problems writing to excel... When I enter the information I need to be written on the excel in an inputbox, this pops up "COM object that has been separated from its underlying RCW cannot be used."Heres the Code:
Code: Private Sub editmodelbtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles editmodelbtn.Click
I am trying to use a 3rd-party Interop assembly called SmartWIM.
I have added it as a reference and added an Import statement
Imports SmartWIMLib
I then initilalise it with
Dim objSmartWim As New SmartWIM
All pretty standard stuff, I've done this countless times with Interops. However, whenever I try and use any methods I get the following error [code]...
I'm kinda new to using VB.NET and certainly with the Excel Interop.I have the impression that I'm doing something wrong in these simple procedures. I keep getting errors on them:
[Code]...
The first procedure fills a combobox with all the worksheet names of the workbook.The second procedure copies all cells in the selected worksheet to an array.The error is the following: System.NullReferenceException: Object reference not set to an instance of an object.I think the error is in the cleanup part, when I set the objects to nothing and close everything. Can someone confirm if this is good or wrong code and maybe point me in the right direction?
I Programe a COM Library in VS2008 to use in Excel , but I'm stuck with an error that I don't understand.
I use this two classes , that compile and register OK. One Class QBitems return a nongeneric collection of QBItem but when I tried to use the Add and/or Remove Method, I receive the following error in Excel VBA :
Run-time Error '438': Object doesn't support this property or method.
I added a class (SImpleClass) in the library and I called from VBA it returned the QItems collection without problem.
NEW: When I replace the QBItem object with a string in the Collection QBItems everytthing works OK. It looks like interface doesn't like to pass an object like QBitem class
Excel/VBA: Sub Pru() Dim obj As New CollectionCOMClass.SimpleClass Dim Itms As New CollectionCOMClass.QBItems
I have a .NET application that interops with a VB6 COM DLL. After installing the application on a Vista machine, I try to execute the code that consumes that COM component and I get an error attempting to read or write protected memory. The system's DEP is set to only essential programs and services, but apparently that automatically applies to .NET applications. When I tried to exclude the application from DEP, it said that DEP must be on for this program (could not be turned off). I had to use the bcedit.exe program to manually turn DEP off system wide and then reboot. After that, the application ran without a hitch, but this is not the route we want to go for our users. Are there any solutions/recommendations for this? It seems as though DEP has been more of a headache than not.
I am creating a report in my asp.net application. The report outputs to excel using the excel interop. Some calculations in the report cause excel to display "Inf" or "NaN" I want to force these calculations to zero so that the report displays zero and NOT "Inf" or "NaN"
I have tried (unsuccessfully) to save the file as an XLSX using the following code:

I get a This extension can not be used with the selected file type error)
I've developed a vb.net app which works great on my dev machine, both within the IDE and as a compiled executable. But when I deploy it to a user workstation, I receive the following:

I am trying to Import an XML file into Excel and then Export the data to CSV. I did the Import Data steps manually in Excel while recording a Macro. I am basically using those commands in VB.NET.
