It looks like the object you are returning is a DataRowView Object.
Try
Dim ComLevelID As Object = cbComLevel.SelectedValue
Set your breakpoint on the next line and look at the value of ComLevelId in Watch Window to see exactly what you are returning and modify your code to fit.

Thanks for reply.
i put a breakpoint on that code line, then the watch window return value "Nothing" for comlevelID, and i press F10,while it jump to next code line, the watch window show that the comlevelID is "{System.Data.DataRowView}". Is it cannot get the selectedvalue?
Best regards,

What is happening is you are returning a object not a integer, so what happens is when you use the toString method you get the text of the type, in this case the System.Data.DataRowView. If you made the changes I suggested you should be looking at the object and not the Text. You should be able to expand the object to see what property or method you need, most likely :
cbComLevel.SelectedValue.Value or cbComLevel.SelectedValue.Row

I wrote a macros for a customer in Excel 2003. He didn't tell me he used Excel 2000 until after the project and like an idiot I forgot to ask. The macros will not run on his version of Excel 2000.
So he got a version of Excel 2003 and the macros will still not work for him. I have tested this macros on other machines using 2003 and they all work correctly for me. I live in the US and the customer lives in the UK. When he runs the macros it immediately goes into the debugging window and highlights a bit of code that simply references the path of the existing folder to a variable. The exact code is:
DestFolder = ThisWorkbook.Path & "\"
There is a compile error with a message that the data folder or project cannot be accessed. The folder the macros resides in that I zipped and sent him was not password protected by me nor can I think of why he cannot access the path to the folder with this bit of code.
Does anyone know if there any issues between UK versions and US versions of Excel that I don't know about? Any ideas?
Also would it help for him to download .NET framework considering he is wishing to use macros? Would that clear up any of the compiler issues?

how to get the filename of the file being open and pass it to the associated application..
|

yeah i have it already.. my problem is how to get the filename of file being opened.. i want that my application know the filename of the file being opened..

This is in the article that he referenced.
Click on "&Open". You will see in the Properties window "Name", "Arguments", "Verb". Verb is hidden from the user, but is the key that is stored in the registry. Leave it the same as the name, but without the "&". The default for "Arguments" is "%1", which means to pass the full path and filename to your application. You can add other stuff here as well, if you need to pass flags to your application to do special stuff. All this information is getting passed to your application on the command line, so you'll need to be familiar with the "Environment.CommandLine" object.
It looks like the information you need will be passed in the command line that starts your application. So use enviroment.commandline to access it

Hello everyone,
In our project, we created a SSIS package to load data from Excel into SQL2005 database.
Right now, I want to write code (whatever is vb.net, Vbscrip, or SQL code) to change the existed excel worksheet name. If anyone can give me any suggestion with it, I will really appreciate it.

Someone please help!
I am using the following code:
Dim h As System.Net.IPHostEntry = System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName)
Me.Text = "Local IP: " & CType(h.AddressList.GetValue(0), IPAddress).ToString
In Windows XP, this results in the top bar showing the local first ip address
eg:
Local IP: 192.168.1.11
When this same code is executed on Windows Vista,
it gives:
Local IP: fe80::7811:d6fc:e34d:2102%8
which is the ipv6 address.
My question is - how can I make sure my code retrieves the ipv4 address (always - even on vista).
I am stumped...
(I already have a way of detecting if I am running on Vista or not as the OS - in case it requires
different code..)
I can't find anything on this issue on the net either which is annoying...
Thank you for any feedback on this..

search in the visual studio help on IPv4InterfaceProperties Class see if that info helps

I've got an error message (no. vbc30205) when I'd try to make a dataadapter.
and compile error is  "End of statement expected."
Dim dataadapter As New OleDb.OleDbDataAdapter=new oledb.OleDbDataAdapter(connectionstring)
What Does It Mean?

Are you sure the error is occuring when you create the dataadapter object? It sounds like what you get when you have an SQL statement that isn't properly setup and you try to run the sql through a dataadapter or command object.
If I were you I'd double check my connection string and then check SQL statements.
And another thing...your statement seems wrong. You shouldn't have to new the adapter twice. And in visual studio 2005 I do not see a constructor that uses just the connection string for an oledb dataadapter. I think your statement should look more like this:
Dim myAdapter as New OleDb.OleDbDataAdapter(strSelectCommandString, strConnectionString)
Hope this helps.

I have noticed that the hide method and the visible property of the tab pages are only accessible to framework classes and not to developers. If I need to hide certain tabs I have to remove it from a collection of tab objects. Here is my question:
What if I remove a tab from the collection and then user shuts down the app, or the application crashes then what about the removed tab page? Is it gone? What can I do so I always have the tabs but only show the ones I need?
Does that make sense?
Thanks b4 hand.

Obviously, when your app restarts, it recreates the tab control, with all the tab pages, your code defines this.
The only way I've found to add/remove tabs is to remove them, changing their visibility just doesn't work.

Im only a student soon to be graduate..were doing our thesis "Project development" we came up for an idea to make a system "thumb mark recognition system"..and for me it is impossible,it is my other co-member idea..
i know im helpless, but i do the program of it..cause in our group were only 2 programmer out of 5 members,other are web developers.
by the ways im blitz002 female from philippines..would you help me to make sure it is possible to make it on vb.net..thanks for reading....hope you reply it to me...
|
|
|
|
|
i believe it's possible to buy a system and integrate it with vb.net. vb.net cannot make it on it's own. you need the hardware for the finger print reader etc.
|
|
|
|
|
Yes, I have a client who has written a similar program. It's not much of a project tho, the fingerprint reader comes with the SDK to match fingerprints, so there wasn't much coding involved on their end.

If you do a Google search using the terms: fingerprint reader you can find a lot of information. There are many vendors for this peripheral. Microsoft is one possible vendor. Their device was listed on Amazon for about $23 (US dollars).
Good luck with your project.

I am inserting somewhat large files into an MySQL database. After about a minute or so I will get this message:
The CLR has been unable to transition from COM context 0x1a3008 to COM context 0x1a3178 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."
It give the options for me to continue importing the files or stop. The program works fine its just this message that I am getting. Any ideas or solutions will be greatly appreciated.
