VBScript & Access MDB - 800A0E7A - “Provider cannot be found. It may not be properly installed”

喜欢而已 提交于 2019-11-26 22:57:51
I've having a problem with a VBScript connecting to an access MDB Database. My platform is Vista64, but the majority of resources out there are for ASP/IIS7. Quite simply, I can't get it to connect. I'm getting the following error: 800A0E7A - "Provider cannot be found. It may not be properly installed" My code is: Set conn = CreateObject("ADODB.Connection") strConnect = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\database.MDB" conn.Open strConnect So far I have ran %WINDIR%\System32\odbcad32.exe to try to configure the Driver in 32bit mode, but it hasn't done the trick. Any suggestions

问题 I'm using Microsoft Access unfortunately because of higher forces and trying to update a record with no luck. This is the code: private void UpdateContact(Contact contact) { using (OleDbConnection db = new OleDbConnection(_connString)) { string query = "UPDATE [Contact] SET [FirstName] = @FirstName, [LastName] = @LastName, [MobileNumber] = @MobileNumber WHERE [Id] = @Id"; OleDbCommand cmd = new OleDbCommand(query, db) { CommandType = CommandType.Text }; cmd.Parameters.AddWithValue("@Id",

DBNull in non-empty cell when reading Excel file through OleDB

问题 I use OleDB to read an Excel file. One of the columns has a "Common" format and contains both strings with letters and values consisting of numbers only. String values are retrieved without problem, but pure numerical values are retrieved as DBNull . How to solve?

问题 I am running following code /*Fetchinch Last CustID from custMaster*/ int ID = 0; try { con.Open(); da = new OleDbDataAdapter("select max(Id) from custMaster",con); DataSet ds = new DataSet(); da.Fill(ds); for(int i=0;i<ds.Tables[0].Rows.Count;i++) ID=int.Parse(ds.Tables[0].Rows[i][0].ToString()); con.Close(); } catch (Exception ex) {} finally { con.Close(); } I am putting debugger from the first statement of try block and finding that error is coming when I am trying to open the connection.

Scientific notation when importing from Excel in .Net

百般思念 提交于 2019-11-26 21:50:16
问题 I have a C#/.Net job that imports data from Excel and then processes it. Our client drops off the files and we process them (important because I don't have any control over the original file). I use the OleDb library to fill up a dataset (I hate writing that code. Seriously, is there any code that a .Net developer dreads writing more than that?). The file contains some numbers like 30829300, 30071500, etc... The data type for those columns is "Text." Those numbers are converted to scientific

SSIS: Filtering Multiple GUIDs from String Variable as Parameter In Data Flow OLE Source

拈花ヽ惹草 提交于 2019-11-26 21:46:17
问题 I have an SSIS package that obtains a list of new GUIDs from a SQL table. I then shred the GUIDs into a string variable so that I have them separated out by comma. An example of how they appear in the variable is: '5f661168-aed2-4659-86ba-fd864ca341bc','f5ba6d28-7283-4bed-9f11-e8f6bef225c5' The problem is in the data flow task. I use the variable as a parameter in a SQL query to get my source data and I cannot get my results. When the WHERE clause looks like: WHERE [GUID] IN (?) I get an

Could not find installable ISAM

I have the following code : string excelConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\db\suc.xls; Extended Properties=""Excel 12.0;HDR=YES;"""; // Create Connection to Excel Workbook using (OleDbConnection connection = new OleDbConnection(excelConnectionString)) { OleDbCommand command = new OleDbCommand ("Select * FROM [Sheet1$]", connection); connection.Open(); and i get the following error : Could not find installable ISAM. at connection.Open() . Any ideas ? There's no 64 bit version of the Jet OLEDB drivers, so if you are running this on a 64 bit OS you might need to

Check if ADODB connection is open

I'd like to test if rs is open so I know that it needs to be closed but the following does

How to connect to a MS Access file (mdb) using C#?

放肆的年华 提交于 2019-11-26 20:47:15
I'm trying to connect to a mdb file and I understand that I would need Microsoft.OLEDB.JET.4.0 data provider. Unfortunately, I do not have it installed on the (University) machine. Since, they don't provide that provider, I believe there should be a way around. How can I connect to the file without Microsoft.OLEDB.JET.4.0 or is there any alternative ? I have following providers: I have tried using OLE DB Provider for Microsoft Directory Services , to which while testing connection, I get 'Test succeeded but some settings were not accepted by the provider'. I took that string and used it anyway
