I am trying to open/read excel (2003) file in vb.net but I m keep getting "Unexpected error from external database driver (22)". I have also tried SSIS but same error pops up. I have used following connection strings but none of them seem to be working:
conn.ConnectionString = "Driver={Microsoft Excel Driver (*.xls)};" & _
"Driverid=790;" & _
"Dbq=C:Report_1.xls;" & _
"DefaultDir=C:;"
When I attempt to bring a database into my VB.NET project, I get the following error message:

Trying to figure out if there is anyway built into windows 7/Vista/XP and/or Dpinst to verify that a driver is installed? I created a program that uses DPinst to install a driver and now I need to figure out how to tell the user that it is safe to close the program once the driver is install as the driver takes longer on some machines to install. Would anyone know how to get this to work?
View 7 RepliesIn duplicated code using Lockbits in VB to obtain the address of Bitmap.Scan0, the first is OK, in all applications, but the second NEVER is. What is the explanation please? Surely both StartAddrA and StartAddrB should be valid pointers to Bitmap.Scan0 for calls to valid, functional ASM code in the functional DLL. The error is, it seems, in the VB Lockbits process. Using VS2010 Beta 2 and XP.

Ok so i have a date time picker that holds a date that was entered by a user. My program works fine when ran on a computer using English(US) regional settings, but when i take it to a computer running any other regional settings, I.E. English(UK), which is the 2nd most common regional settings that will find its way to this program, I recieve an error because the Date format is backwards. What i'm curious about is how can i grab the system Regional Date format in order to rearrange my Date to fix its context?
I know that since the date is stored as a string i'm going to do something along the lines of this to break it apart:
Dim temp()
temp = Split(inputarray(7), "/")
inputarray(7) = temp(1) & "/" & temp(0) & "/" & temp(2)
i am almost 100% sure the above code will take a date in MM/DD/YYYY format and rearrange it to DD/MM/YYYY format.

We have an application (Vb6) that gets installed at all of our client sites and they often (Vista/Windows 7) run into a the error message Unexpected error, quiting after a install on a new machine. The problem comes about when the UAC is on and the application is trying to create registry entries in areas it doesnt have access to because the application is running as a standard user. If the user runs the application as an admin the first time, everything sets up and life if good.
My question is, what is the most elegant way to setup those registry keys without forcing the user to run as an admin the first time? We could force them to run the applicaiton as an admin using a manifest file, but I dont want them to have to run as an
admin every time, just the first time.

I am reading a large number of XML files and do not want my program to bomb on exceptions. I am making great strides in reporting the errors, skipping the offending files and continuing the import process. However I am having problems with XmlExceptions. I get the following XmlException on the While textReader.Read() line of my program:
Quote:
XmlException was unhandled
Unexpected end of file has occurred. The following elements are not closed:
my:PicInsert, my:PictureGroup, my:myFields. Line 153, position 430817.
I am finding some of the reasons why, missing tags etc, but those aren't really my concern. I just want to report the issue and continue. I am thinking about some kind of check for a valid xml file but fear that that might not catch it all. For example I had a image tag in one of the files that was missing an alt="" attribute and I am not sure if that would invalidate the entire XML file.What would be the best way to trap and deal with the exception with out causing interuption to the program?

In my MDI Application code I have a form that launches a second form then hides itself until the spawned form closes. It works great unless I choose to close the application while the spawned form is still up.
The following is some example code.
Dim ChildForm as New frmTaskWindow With { .MDIParent = Me, .AddingNew = True }
ChildForm.Show
Me.Hide()

Me.Show() ' error occurs here because my form is already closed by the system. Is there a way to get around this without just an error catcher?
I'm connecting to my mysql server using ODBC in vb.net, the database is shared throughout the company because it is used in an accounting program (simply accounting), each user has their own account user/pass to login to the database. I have developped a program that uses the accounting database and combines it with other information, my problem is that at least once a day I get this error when I run my program: "(10061) ERROR [HY000] [MySQL][ODBC 3.51 Driver]Can't connect to MySQL server on"and the error persists for at least 4 hours, for some reason it starts to work again later on in the day.

I am building a client in VB.net for calling webservices methods from a partner organisation.[URL]../system.web.services.protocols.soaphttpclientprotocol%28v=VS.71%29.aspx because I can't get it to work using the Web References feature of Visual Studio 2010 (when I try to do that it turns the methods from the WSDL into classes).I have created a proxy class and can instantiate an object of that class no problem.
However, when I try to call a method which requires arguments I get this error:
Unmarshalling Error: unexpected element (uri:"http://api.service.apimember.emailvision.com/", local:"key"). Expected elements are <{}key>,<{}login>,<{}pwd> Does anyone have any idea why this might be? (If it's helpful I can post my code and the location of the WSDL.) (P.S. I can get the whole thing to work fine in PHP using ZF Soap classes, but for various reasons I need to get it to work using .Net)
Edit to add: I have used Wireshark to examine the outgoing and incoming SOAP message to compare them with the messages being sent via SoapUI, where it all works fine.What this has shown is that my VB client is sending a message where the namespace of the web service I am trying to access is declared as an attribute of the method, and not in the soap:envelope attributes.

This error message happens about once a week from one of our sales staff, and I haven't been able to isolate why. It always seems like everything deletes and Backups normally. If they unplugged their network cable I would expect the delete or backup to fail, so I don't think thats the issue.
I'm currently doing a project that includes access 2010 My question will be what driver can I use for an access 2010 *.accdb type file? For a *.mdb it works perfectly well with
ConnString ="Driver={Microsoft Access Driver (*.mdb)};Dbq=" & Application.StartupPath & "\CITSDB.mdb;Uid=Admin;Pwd=123;"
But, when I changed the mbd to accdb:
ConnString ="Driver={Microsoft Access Driver (*.accdb)};Dbq=" & Application.StartupPath & "\CITSDB.accdb;Uid=Admin;Pwd=123;"
It resulted in errors:
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'.
ERROR[IM006][Microsoft][ODBC Driver Manager]SQLSetConnetAttr failed
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'
And then it shows me that my code for
If dsLogin.Tables(0).Rows.Count = 1 Then
IndexOutOfRangeException was unhandled
Cannot find table 0
I knew it must be the driver but I don't know what accdb driver I can use for the connstring.
