问题 In the end I want to grab a OLE type image from an Access Database and put it into a picture box. Working with Visual Studio 2012 in C# and MS Access 2010. My solution is an app non-web related.

OleDbConnection l = OleDbConnectionDAO.createConnection(); Equipamento eq = new Equipamento(); try { OleDbDataAdapter adapter = new OleDbDataAdapter

问题 I want to use access 2000 and 2003 databases in access 2010. Since I don't want to check if everythings's working manually I am looking for a tool that analyzes VBA code for errors or compatibility issues that occur using access 2010 (or if available at least access 2007). 回答1: See utility here and explanations here.

问题 I am trying to set up a form to use a disconnected ADODB.Recordset as its source. The issue I have is that changes are not saved into the original Access table upon closing the form and replying "Yes" to the prompt. What am I missing ? Note: Please don't tell me the method is useless, it's just a POC with a local table, I plan to try later with a more "distant" recordset. Dim conn As ADODB.Connection Dim rs As ADODB.Recordset Private Sub Form_Load() Set conn = New ADODB.Connection conn.Open

问题 I want to link the result of a query to a Textbox but I get this error: here is my code: Dim rst As DAO.Recordset Set rst = CurrentDb.OpenRecordset("SELECT XValue, YValue,Wert FROM tb_DCM_Daten WHERE (FzgID=" & Forms!frm_fahrzeug!ID & " AND Name='" & List2.Value & "')") Text10.Text = rst!XValue //error in this line It should be return c.a 20 record Why do I get this error and how can I solve it? 回答1: One possible reason for the error is that Name is a reserved word in Access, so you should

问题 I have an Access 2010 database with all tables linked to SQL Server 2014 tables. I have an Excel 2010 (.xlsx) file (though it starts as a .csv, and I could leave it that way), that I need to import into a SQL Server table via VBA code. I know that there are import tools available to do this, however, I have 20+ XLS files per month to import, and would rather have an automated method of doing this. All my VBA code resides in the Access database, and all the examples of VBA code I've been able

问题 I have the following problem: I am using two queries to parse imported data, they are both selecting data The imported dataset is pretty complex, but this reproduces the error. QueryA: SELECT CDbl(FieldA) As DblA, Imported.* From Imported WHERE FieldA IS NOT NULL QueryB: SELECT * FROM QueryA WHERE DblA > 7 AND DblA < 600 QueryA runs fine, QueryB throws an invalid use of null error If I insert the results from QueryA into a table and run QueryB against that I do not receive the error, however,

问题 I have a table for which I want to return the top 3 records by ErrorMargin per week commencing in Access 2010. The problem I'm having is that 0 values are being ignored and I'd like to see just 1 record in the case of ties where the tie would take the total number of records over 3.
