Error on dataAdapter
-
Could someone tell me what I am doing wrong? I am trying to add access into visual basic. I have changed the server for access (Microsoft Jet 4.0 OLE DB Provider). I have done the test connection - all is well. I have added the dataGrid to the web form- Named it MyDG1. I clicked on OldDbDataAdapter and added the connection where the access page is. I have done the Query builder, generate dataset (which I called MyDS). I selected the the dataset and Previewed it - all is well when I filled it in. I assigned a table to the DataView - Shopping Products (my access page). I assigned the DataSource property on the DataGrid as DataView1. In the page_load handler I added OleDbDataAdaper1.Fill(MyDS1) Page.DataBind() I build it - all is good; however when I view in browser that is when I get my error. Here is my error. Server Error in '/WebApplication1/WebApplication1/Unit5' Application. -------------------------------------------------------------------------------- Unspecified error Description: An unhandled exception occurred during the execution of the current web request.

first thing we can find out about the error is to put a catch block and verify what exactly is the error. looks like you dont have any exception handler. and another thing you may have to look in your case is, you are using a typed dataset. so, when you try to fill it using adapter, it will have to fill in according to the tables structures defined. if the the 'SQL' using which you are filling dataapater does not follow the schema in typed dataset, it may fail. verify.

Sorry, I am just learning. :confused: Thanks, Thank you, ibok23

i think for dataadapter, there is a validation event which will fire when the incoming data does not comply with the schema. not sure thouhgh. please check on the validating events Bhaskara

I am sorry, I am new at Visual basic and ASP.NET. How do I check the validating events? Thank you, ibok23

ok, THis is helpful; however, i need to check out a folder to see if the read/write permissions for userAccount are not enabled in a certain folder. here is the folder Document settings\ServerName\ASPNET\LocalSettings\Temp I am not sure how to find this folder. The server Name is the server that I am using. is that where I went to change to MIcrosoft Jet 4.0 (because of access). I am sorry, I am lost. Thank you, ibok23

ok, I'll start from the beginning. I am trying to add access within Visual Basic. I followed the instructions that was given in my book. I also looked over the site that you suggested, it basically told me almost the exact same steps. The only difference was that it said to be in Visual c#. My book, which I have to go by, says to be in visual basic. Thank you, ibok23
