I defined a picture column as Image type. Created the Datasource and placed an Image control on a form. When I input the picture of a client in the input form every thing works fine but when I Open a second form (the search form) and try to search for a client with picture I get the following message:Inconvertible type mismatch between SourceColumn 'Picture' of Byte[] and the DataColumn 'Picture' of String

I have a question. When I try to use this piece of code in my program which will add a supplier to the database, I encounter data type mismatch error. As far as I know, the status of the supplier creates the error.How would I store the values of the radio buttons named radActive and radInactive in the database? Should I use Boolean or a String? I am using Microsoft Access as my database and the field of Status is set to Yes/No.

I have tried repeatedly to use a For Each Next statement inExcel 2003. The intent of this is to ititerate through a predefined selection of cells and set the value of the cell 3 columns to the right based on the value of the cell in the selection.
The latest code I have tried to use is the following:
SR.Range("a5").Activate
SR.Range("a5", ActiveCell.End(xlDown)).Select
Selection.Offset(0, 5).Select
[code]....
Where SR is the active sheet. (I have only been introduced to VBA and code language for a few weeks, so I am learning as fast as I can. Please excuse my ignorance!)When I get to the 'If x.value' line I get the type mismatch error. I have tried to set my "each" to variant variable types and my "collection" (or selection as it were) to different variable types and constantly I am getting this same error regardless of my efforts.

I have to implement a COM class with VB.NET. An object of this class has then to be created from a VB6 DLL. The code for the COM dll is very simple:
Code:
Public Class AdapterWrapper
Implements SchemaCompInterfaces.IEFAdapter
#Region "COM-GUIDs"
[code]....
Now when I'm running this code, I'm getting the Run-time error '13' Type mismatch in the CreateObject line. Late binding with
Code:
Dim adapter as Object
seems to work for my test code, but is not a solution for me, because I can't change the proprietary VB6 code where the COM object is created. So somehow the interface "SchemaCompInterfaces.IEFAdapter" is not known... :sigh: In the project properties I checked the flag for registration with COM-Interop. Perhaps something to do with the ClassInterface?

im trying to use this select statement on a OLEDB database and im am getting a data type mismatch.[code]its not just this particular select statement. its any where the where clause is dependant. in the past i have got round this by passing in a parameter but its not my prefered method and id really rather not pass in two dates as parameters.i have looked in to this and found some thing that said that in oledb select commands you need to CONVERT the dates however when i trid that i got an error thar says somthing like CONVERT is not a recognised function.

I am using parameters in my code to update records in an access database.
One of the fields I am using in my sql Query Update statement is the ID field and it is causing this error -
Data type mismatch in criteria expression.
I have isolated the error and it occurs with the ID field in the Update query.
The DataType for the ID Field in Access is AutoNumber, Field Size is Long Integer and New Values is Increment.
In my code I have declared the Data Type as Integer.
Is there an obvious mistake in my code?

Probably a simple problem but I'm failing to see how or why it's happening.
The error message I'm getting is Data type mismatch in criteria expression.
My coding is below:[code...]
The error is coming up when i'm filling the dataset, i've already figured that it works when the WHERE is removed.
So i'm assuming the mismatch must be from (VirtualLearningExercises.Level = '" & UserLevel). UserLevel is defined as a integer in vb and VirtualLearningExercises.Level is data type number on access.
I've had this problem many, many times. And it's always turned out to be a small typo or "" around an integer, but I just cannot find what's wrong with my SQL Statement this time! SELECT Card_ID FROM Payment WHERE Customer_ID = 12 AND Card_Number = 1231231231231231 The table and fields are named correctly (the table is actually a query).The only thing I can think of is the card number being too large, however it works fine in my INSERT INTO statement!All of the fields are formatted as their respective data types, ie. Integers are set to integer, not string.

Please see bottom edit for where I am currently at I have created a pivot table that works fine when the pivot cache is defined as:
Dim ptCache As Excel.PivotCache = mainHighway.PivotCaches.Add(SourceType:=Excel.XlPivotTableSourceType.xlDatabase, SourceData:=mainHighwayData.Range("a1:v7500"))
My problem is that the number of rows changes from day to day, so I figure out the number of rows in the worksheet and then use that in my pivot cache:
Dim highlRow As Integer
highlRow = mainHighwayData.Cells.SpecialCells(XlCellType.xlCellTypeLastCell).Row
Dim ptCache As Excel.PivotCache =
[code].....
This returns the proper number for the last row, but once again throws the same type mismatch error.
Edit: I found out another bit of information, but I am not sure what to do with it. The pivot table works fine if the values in it are <= 65536, but the second I increase the range to 65537 I get the type mismatch that has been haunting me. This is true for all numbers >= 65537. I know that 65535 or there abouts used to be the last row in excel, but that is no longer the case. Also when I create the pivot table manually in excel I have no trouble and it has all of the data. I am using int or long, so it should not be an overflow or anything. Anyone have any thoughts on why VB.NET will not let me make a pivot table based on data with more than 65537 rows?
I run a query on Access and although it warns me about null fields, it can still run the query and add the rows.However, when I run through JET in VB.NET, it says "Data type mismatch in criteria expression".Is there a way for JET to behave like Access (ie. still run the query and add the rows)?

I am using Access 2007 as an automation server for a custom form in Outlook 2007. I am trying to use the records in an Access table as a rowsource for a Outlook combobox. I have been debugging it quite a bit; I can tell that I successfully grab a recordset and can tell that they are the correct values. The only problem is when I try to add an item to my combobox (cboCategory).I checked the properties of the additem function and it expects a variant, so that's what I give it. However at runtime, it gives me a type mismatch error.
