I use Visual Basic in Access, and I have no problem writing data directly to a cell in a database table. But I can not figure out how to write the code for Visual Basic 2008. For example I would
use Me![cust_Cost] = 20 to input 20 in the database table.
I have purchased two different Books on Visual Basic 2008 and not one of them show how to input data manually.
I'm using Microsoft.Jet.OLEDB.4.0 to set/get data from database access file, but it isn't working perfectly on 64-bit systems, so I'm looking for an alternative way.set/get data from database access file working on 64-bit systems.
I have searched all over the forums and not found an answer to my question. My question is how do i write to an access database at runtime. The database is also created at runtime. I have a dataset loaded with a table that i needs to be written to the database. how would i write each row of my dataset to my database? Sorry if this sounds a little jumbled together it is late and i am tired. If it is unclear you can ask me and i will answer any questions you have about my question.

What i've written opens an Access database and one can read and write into it (on a table called Journal)It does indeed work for newly made Access files. However it doesnt work with a specific Microsoft Access database (again .mdb) which was made with a very old Access, like Access 2000 or something.The error message is: Syntax error in INSERT INTO statement.Inside the zipped file below you will find the source code of the program, along with an access file that the program CAN read, and the one access file that i NEED the program to reed but it cannot!
To see what i mean run the program one, try to add a new line to the database. you get an error!now rename the Journal.mdb to "journal.bak.mdb. And the journal_working.mdb to Journal.mdb try to add a new line to the database again without altering the source code at all. it succeeds now!!
NOTE: the program can READ data from both files. but it CANT write data to the old access file
this is the code:
Dim cb As New OleDb.OleDbCommandBuilder(da) Dim dsNewRow As DataRow dsNewRow = ds.Tables("AddressBook").NewRow() dsNewRow.Item(1) = txtFirstName.Text 'or .Item(1) =
I can save my data to access database and in the access database field I set it to date/time.But problem is when I get the value out from the database.. the format is always month/day/year hour:minutes:seconds example today: 5/2/2011 12:00:00..How to get the value into listview becoming May/2/2011 without the hour..Here's my code to get it from database ListView1.Items(i).SubItems.Add(dt.Rows(i)(14).ToString).The second problem is.When I would like to edit, how can the datetimepicker get the listview value ? [code] info: using access 2003 (.mdb) the Date of Birth field has been set into Date/Time.
I want to be able to click on the save icon and have the data on the form save to the original database. Right now I seem to have a disconnected dataset I have tried to change everything from read only to a false statement but it just will not work. It saves to the form fine just not the orignial data base.
I am trying to write data back to my database in my project, but it keeps disappering when I make any changes to code. I can build the project, add data, close the project and build it again and the data is still there. But as soon as I make any changes to anything, on the next build, all of the data is gone.
The table will not be bound to any controls in the final project, but for testing purposes I have a datagrid control that it is bound to. My code started as follows:
I'm makin an application which will calculate the amount of carpet needed to floor a room, i would like to add in an order management bit too the application so that the user can add, delete and amend pending jobs. I'm a bit of a beginner so i don't know which way is really best to go, should i use file writing on database? I will be takin values from variables and textbox's if thats of any importance.
How can I change the delimiter when writing my Access table to a text file? I was hoping it would be as easy as adding a similar option like we do for HDR=No; maybe Delimiter=|
Dim AccessConn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|mydatabase.mdb")
AccessConn.Open()Dim AccessCommand As New System.Data.OleDb.OleDbCommand("SELECT * INTO[Text;HDR=No;DATABASE=" & userPath & "].[" & fileName & "] FROM tblMyTable", AccessConn) AccessCommand.ExecuteNonQuery() AccessConn.Close()
I've been doing some more experiments and have summarized the query as below: I've created the simplest application. A project with a plain form, which writes text file within its application directory. Simple as that.Supposing this was my application which I want to distribute on the world web. I've created a basic installer for this using NSIS installer. The Installer installs my application in a folder created inside Program Files. The OS is Windows7 and UAC is enabled.Now I know many people have been facing difficulties in accessing files inside the Program Files folder. My app is simply creating a plain text file, nothing more, and within its own application directory. It is giving Access Denied error. But if I right-click on the EXE and run it as Administrator, then it works ok.The only solution thats available is not to write in the application folder, and write text file in some other folder which is not protected. My question is that other programs that are installed on my system are also doing it. I have a temperature monitoring software called SpeedFan on my system, it creates log files within its app directory. All other softwares create log files within their app directories, why cant I?I just have to make a small log file for my application and Win7+UAC is not letting me do it. I don't want to write the small file in any other folder. How are the other softwares accomplishing this ?
I am creating a fault tracker AKA issue tracker. It is going to be very simple in functionality. As of right now I am using a text file as a database for the end user to store current issues.
The reason for me using a text file is that I do not know much about database programming and I cannot find any simple examples in the same usage. My question is, is it really going to become a problem as more issues are added to this file and it becomes larger? I.E using up more resources, application getting slower etc?
If so, could anyone point me in the right direction to creating a simple database application. Most examples I have seen require ask to download their pre-made database. Although I would like for the program to create a database if one is not there.
I am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?
I am working on a program for work and I am stuck on trying to make a new XML file from VB.NET 2010. I have the old code which was done in C# and it works but even using a C# to VB converter didn't help. I will paste in both the C# and what I have in VB
I am trying to write the TOURN structure and then read the TOURN structure back in.. the file gets created on my desktop and the program does not have any syntax errors, but when I READ the file none of the Data gets retrieved. So I am not sure if the DATA was actually saved or it is just not being retrieved?? This is what I have coded so far...
The program that I am writing has three default variables that I would like it to store and also be able to change. I have them in a text file called "settings.txt" The format of the text file is as follows:
The field descriptions eg "Default Source" take up 30 characters, so the variable data starts with character 30. I know their has to be an easy way just to pull out the data from a particular line starting with character 30 but I can't find it.
Im trying to get some particular content from a site and place it in text file. i have used a listbox for loop of urls i want to process and another to see output of data. now i want all data in text file each item seperated by "~" sysmbol.

I'm working on a project where I have to allow users to write data to an existing Excel worksheet (by entering the data into a form created in Visual Basic.NET). I've created a form that allows users to enter data such as the following:
Name (First, Last) Mailing Address Email Address Gender Age
...and so on. I've programmed the data to be sent to the Excel file upon clicking on the Submit button in the form itself. I've also created the Excel file and placed it on my C: drive, but the problem I'm having is trying to send the data from the VB form to the Excel file itself. Can someone please show me some sample code or point me in the right direction as to how to get the submitted information from the form to save into the Excel file, please?
I'm trying to get the information to show up in rows and columns in Excel like the following below (the dashes are just to show that the information should be in rows and columns):
Name--------------------------Mailing Address-------Email Address-------Gender-------Age John Doe---------------------2300 Jackson Street-------- xxx@xxxx.com-------Male---------17
