I have a problem that hopefully someone can shed light on. My OleDBdataadapters and OledbTableadapters have gone on strike In a simple vb.net 2005 pro project I have an Access 2003 .mdb with 2 tables each with 1 primary key and all other fields allowing zero length and not required. The database (not read only) is included in the project (see connection string below which works because data is presented on bound forms).
Although each table's data is displayed on one of 2 bound windows forms, it just refuses to update, add new or delete. I've deleted and recreated forms, etc, using wizards and just run time code but the problem is still there. I can change data manually in the mdb. The code below refers to a site mdb table and was wizard generated. I added an update query to the TableAdapter using the wizard, see sql below.

I have a problem in updating statements, can't write it correctly, every time I try to edit it, gives me different error (ora-01036 illegal variable name/number, missing expression, invalid identifier).
I have a bindingsource question, didn't know if anyone had run into this before, but,there are several textboxes I put on a form, the text of each textbox is bound to a field in a table from the bindingsource. Why is it when I update the tableadapter, some of the fields update and some of them don't?
Example:
using the bindingsource
Textbox1.Text is bound to UnitListBindingSource - UnitNumber

View 1 RepliesAssume my form has four text boxes and it's bond with a Dataset, therefore The user can 1-4 fields. Typically I write one update statement that take four input parameters. Therefore I update the updated fields as well as non updated field. To do this in the proper way, how many update statements I have to write?
Or
How do I do this update properly? I use SQL server 2K5
I have a table in my database that the fields of it are not fixed in number and name. in fact this table is the statistical report of other sections of my database.I want show this table in a data Grid View after finish calculation. I created a dataset and connected it to my Data Grid but the number of columns and names of them are not flexible and don't change according new statistical reports that would be available in my table.Is there any way to update my dataset and recreate it according to my new information in my table and show it correctly with Data Grid?
View 1 RepliesI have been tasked with writing a program for our yearly reviews. We want all of the information gathered in the form to be submitted to an access database. I have created the form and the database. I can send info to the database but it is put on a new line everytime it is submitted. I would like to check the first column of the table to see if the user login is already there. If it is there I would like to update the information. If it is not there I would like to create a new row. This seems simple, but I can not figure out how to see if the user login is already there.[code]...

I am building a vb.net application for a client, and there is a problem. I am connecting to a mySQL server, and using the UPDATE command to update certain fields to the specified values, however, once I run this code, the fields on the mySQL server turn EMPTY. Here is my code :

I've been running into some errors with converting strings to dates in the following code. I have recently added the intcall.Value = DateTime.Parse(txtIntCallDate.Text) function which had gotten rid of the error message, however the records are not being updated, any of them on the form. Prior to this the strings were being updated just fine. As long as there is a date entered on the form there is no error, if it's left blank i get the "Problem converting string to datetime"

I am making a booking system. I am using same form for insertion and updation. How can I update by taking the values from the textboxes. For example if the user enters value for just 2 out of 8 fields then How can i update just 2 fields without affecting the rest of the record. I mean to say that if I use a single update query using all the fields then if some textbox is left empty then it will replace the database field value by null or something else.

I'm trying to insert a couple of fields into a csv config file and then update all other rows in the file at the same index by copying the previous 2 entries. I'm reading through each row and converting the row into a list(of String) because it seems to be the most flexible way. Ine initial insert works fine, but the code below doesn't. The actual insert code is:

pcIndex is the list index value from elsewhere in the code at the insertion of the 1st of a pair of values into one row. I need to update that index point and pcIndex +1 in all other rows. However it's not doing anything. Tried using lstSteps.Insert, InsertRange, etc. Am I using this right? Is there a better way? It seems to be over-writing the entry rather than inserting a new column and moving the others up, so it appears the list capacity value isn't updating - so I'm left with the initial row with 4 more entries than the others sticking out of the file.
Let say I have a function inside a class which require 4 parameter (table name,field name,field value, return field) When I use this function my form, such as

Currently working on a project to automate the input based on the Summary file (xls format)
1. I want to be able to do the following: update, append, delete and populate the records to the various files based on two distinct fields, column A & F (see attached file).
2. Researched the process, requires knowing VB codes, are you familiar with this language? If so, how can I simplify the process? Please advise.
3. The files will reside on the SPP.
I'm currently refactoring an old Visual Basic DLL (VB.Net), which stores all of its data in one module called Globaldefinitions as public fields. There are about 200 fields, referenced thousands of times all around the code:
Public Module Globaldefinitons
Public a As Short
...
Public zz10 As Double
[Code]...
I need to change the module into a class with non-shared fields. This means, each and every of these thousands of references needs to reference the instance of that class:
globalDefinitionsInstance.a = 5
How do I go about this efficiently?
Regular expressions operating on the source fall flat. Refactoring tools like Re-Sharper or CodeRush don't seem to offer this functionality. Visual Studio 2010 cannot do it automatically either.
Class Foo
ReadOnly name As String
Public Sub New(name As String, dependentUpon As Foo)
Me.name = name
[code]....
The output of New Bar() is:
Dependent created. Dependent upon nothing.
Independent created. Dependent upon nothing.
It seems fields are initialized in the same order as they appear in the source code, which (a) leads to an unexpected result, and (b) seems a little puzzling, given that one is normally not permitted to read from uninitialized variables in .NET, yet that seems to be working fine above.I would've expected VB.NET to be smart enough to initialize referenced fields first, and only then those that reference it; i.e. I'd have liked to see this output instead:
Independent created. Dependent upon nothing.
Dependent created. Dependent upon Independent.
how to get VB.NET to behave like that instead, without simply having to swap the declaration order of dependent and independent inside class Bar?
I'm trying to create a table in Word using data from a table in Access. There are four fields in the access table that I need. 3 fields are text which I can populate the Word without any issues. However the fourth field is a memo with >255 characters.I'm struggling to come up with the proper code to allow me to populate the Word field with the memo data that has more than 255 characters. The code I have so far is listed below. But when it hits the memo field, it crashes on the line I marked with **. I know it's not text, but I've tried many different field types, but nothing has worked so far.[code]...
