View 5 RepliesI had a working program a while ago, but now it is giving me an error when I try to insert some data to my Excel-file.I get this error: Old format or invalid type library. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD)) For example, one of my Excel referencing codes is:
Dim XL_App As New Excel.Application
Dim XL_WB As Excel.Workbook = XL_App.Workbooks.Open("C:Program FilesIAAExcelitTuntilappu.xls", , True)
Dim XL_WS1 As Excel.Worksheet = XL_WB.Worksheets(1)
The above code used to work, but now it gives me the error...I recently updated my Office from 2003 to 2010. How can I fix it?
I am trying to open an Excel file using the following commands:
xlsWB = xlsApp.Workbooks.Open(filename, , True)
where 'filename' is the name of the file.However I am getting the following error message:
Message = "Old format or invalid type library. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD))"
I originally developed an application where I used the above code with default language setting of "English" (under regional and language settings). When I am changing the language setting to "French", the above errror comes up. I am changing the language setting to French in order to simulate an error when this application is run in a French version computer.
Im getting the fol. message: Old format or invalid type library. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD))when i try to run a code from my vb app. I've just tried to change my regional settings to English but no luck

I requested a Code Signing Certificate from my own domain Certification Authority on my Windows 2008 R2 domain controller.
When trying to publish my code to my webserver via Clickonce, it throws "an error occurred while signing: Invalid provider type specified"
In order to get the certificate I duplicated the Code Signing template on my CA, and tried both options available:
1) must use Microsoft Software Key Storage Provider
2) use any provider available locally
algorithm is RSA, key minim size 2048, Hash SHA1, alternative format unchecked
Having trouble compiling when I have a reference to SHDocVw.

I'm using WMI code and VB 2008 to see NIC status. So far the queries are working, but the methods aren't. For example, I'm trying to set a network card to use DHCP, I get invalid function with this code:

Dim outParams As ManagementBaseObject = classInstance.InvokeMethod("EnableDHCP", Nothing, Nothing)
A co-worker checked a very simple Visual Basic Visual Studio 2010 application into our version control system. When I checked it out and tried to build it I got the weird error below, which I am guessing has something to do with which .Net Framework the build is targetted towards and also which Framework I have installed.

I created a simple user control and everything went fine.Then I created another of the same control (as a different project) from scratch (creating the controls in a different configuration; but pasting code from the previous one from a text file).As far as I know I did everything the same for creating a user controlCreate a Class Library project Then Project>Add New Item> User Control Then delete the initial class that was added automatically (usually named Class1.vb) Put all of my code and components into the user control class.However, when I wanted to run it in the debugger as I did in the previous project, I now get an error message:"A project with an Output Type of Class Library cannot be started directly."
View 6 RepliesI'm compiling a VB.Net 2.0 app (created in VS2008) using msbuild, and now I've added a generic return type, it's giving me the following:
Warning: Type library exporter encountered a generic type instance in a signature. Generic code may not be exported to COM.
Having just spent ages removing all of the previous warnings, I don't really want to add a new one. Any idea how to get rid of it (aside from not using generics)?I don't know what details I'd put in the attribute, or what number to put in the project-level ignore list.

I get an error while trying to install a third party Excel add-in [Thomson One Analytics]. Error: "Compile error in hidden module: Main" Microsoft Excel 2003..But when I had the Addin unlocked.I noticed that it was getting stuck at a specific line in the MAIN module of the Addin package and the debugger throws a compile error message saying that: "Object library Invalid or contains references to object definitions that could not be found". Earlier when I had this issue,I made another user login to the PC and we were able to use the add-in successfully. But this time even a different user with Admin Rights was not able to use it. [code]
Tried to install and run the Addin on the same computer by a different user having admin rights, no go.Made sure that he references for the add-in in the VBA editor are correct, by comparing them with a working computer, no go Re-installed "Service Pack 6 for Visual Basic 6.0: Run-Time Redistribution Pack (vbrun60sp6.exe)", no go.

i know this may seam odd but I'm getting an error navigating through a datagrid of an invalid cast. The trouble is it is of the same types!! I working on customising some Sage code and in the form there is a datagrid that is populated by a series of Sage.Accounting.Stock.TraceableSOPAllocationItems (a batched stock item allocated to an SOP).
I want to give the user some further information on each item so they can decide which batch and bin to use. I want to go through each item in the grid and then go find this extra information for it. the trouble is when I go to navigate through, My VB.Net code throws the error.InvalidCastException was unhandled by user code, Unable to cast object of type 'Sage.Accounting.Stock.TraceableSOPAllocationItem' to type 'Sage.Accounting.Stock.TraceableSOPAllocationItem'.

View 8 RepliesI've created a class that inherits from Dictionary(Of TKey, TValue) called KeyCopyDictionary(Of TKey, TValue). I'm now trying to use a pre-existing function which returns a Dictionary(Of String, String) and assigning it to a variable of type KeyCopyDictionary(Of String, String). I'm getting an invalid cast exception. Is it not possible to assign a variable of a parent type to a variable of its child type? I've tried DirectCast and CType to no avail on this...
View 5 RepliesOk, just needing a 2nd set of eyes looking at this to make sure the error isn't something else other than my LINQ code here. Here's the function class itself:
Public Function GetJacketByPolicyID(ByVal jacketID As Int32) As tblPolicy
Dim db As New DEVDataContext()
Dim j As tblPolicy = db.tblPolicies.Single(Function(p) p.policyNumber = jacketID)
Return j
End Function
and here is the code which calls this class function in the web control form itself:
Dim p As tblPolicy
Dim j As New Jackets()
p = j.GetJacketByPolicyID(3000050)
For some reason it's flagging the 2nd line in the GetJacketByPolicyID function saying the specified cast is not valid. So I'm guessing it's something I'm doing wrong. I'm sure the tblPolicy/tblPolicies class works right since I can create a new instance of a tblPolicy and set a few variables by hand and return it, so that's not it. I've also checked the datarow I'm fetching and there's no null values in the record, so that shouldn't be it either.
You know we have to register a type library for a COM component.My question is do we need to do in .net environment if I created a library?
View 1 RepliesI'm trying to send mail by using 'Groupware Type Library'. I'm using the following code for the task:
Sub send_mail()
Try
Dim strFrom, strSubject, strBody
[Code].....
When I check the groupwise mail client for the status. I can see the mail in 'Sent Items' but delivered status as Pending, also same mail in 'Trash' folder too but with 'To' field empty.
also, if I'm wrong of using the library then also suggest. My basic requirement is to send mail from groupwise that will be sent from toolbar button in groupwise mail client. So I'm creating test app to send a simple mail that can be integrated in the module.
I have an .net app that I created using visual studio 2005 and it also incorporates an autocad .api; therefore, in the project properties, under the application type, I have it listed as a class library.
I'd like to see if I can incorporate a splash screen; however, all the material i read indicates that I need to set the application type as a windows app in order to set the splash screen as the startup form.
I was able to tell the form to load...with out the use of this setting; however, I don't know how to tell the screen to only display for x amount of time. The example code suggests that i create an OnInitializer method by loading the app events..which i'm unable to do.

I have a function that is getting passed a String and a DataRow.The String is a custom formatter. The idea is to do this
String.Format(passed_in_String, DataRow("ColumnINeed"))
The reason this is being done is at this point we have no idea what the column contains.However, if the formatter is "{0:MM/dd/yyyy}" and the DataRow("ColumnINeed") is an integer containing 42, String.Format is returning: MM/dd/yyyy In this situation I need it to throw an exception instead of returning nonsense.Is there anyway to make String.Format throw an exception if the object does not match what the format string is expecting?
I have an assembly containing a number of classes. This is a class library type assembly, not a windows forms application. It's also single threaded.Is there a way to catch all un-handled exceptions so that I can log them?
