i am trying to build a Visual Basic program with an Access 2007 database in the back. I have another Access 2007 database with two tables stored in there. Each table has two columns, a UserID and Password column. This database will be used with a LoginForm so that if the user enters a normal login and password they will be taken to a specific form whereas if they enter an AdminID and password they will be taken to another form with different features. I managed to connect to the database and it works fine but i tried making the passwords and user names case sensitive for better security. I don't have a problem with this when i try only one of the tables, but when i try to implement the second table (to check if the login is an admin or a normal user)
I am not able to add records in an Access 2007 database using VB 2010 Express Edition. I have read other posts and followed them but still I am not sucessful. I have the connection to the access database as MS Access Database, therefore it has the OLEDB connection (not the Jet 4.0). I am using the project instance in binding the text boxes to the fieldnames in the Access database. Did I miss something? I am also using Windows Vista Ultimate.
so i need to link the database but i want to use the bind source way, i dont like using the oeldbadaptionand all it needs to do is perform a search for records, insert new record and save the record but
So i'm creating a simple application as an example that is to link to a Access 2007 database.
On my main form i have four listboxes that are correctly attached to the table, I have one for First Name, Last Name, Phone, and School. I added 3 records to the database in Access to see if I could display the records in the listboxes on the form. I found that it was very easy by setting the properties and I have no problem there. I also have a command button that loads a new form for the purpose of adding a record to the database.
Here is my main form (frmMain.vb)...
And Here is the code for the form...
What i'm looking for is when the user presses the Add button on the frmAddNew form then it needs to close and the new record is listed in the textboxes and saved to the database. Id also like to know all kinds of things i might be able to do with textboxes and databases because i'm trying to learn for a larger project where i'll need to keep track of hundreds of records.
I understand that this is a simple procedure, but i've been spending all night scouring tutorials and getting lost in the msdn library online, so maybe some human input will be better.
i am working on a project that involves checking that a persons login and password are that of held in the database each person has a seperate username and password i seem to have stumbled across an error. here is the code and i will underline the problems
it's just for a program registration. i would store all of the registration codes in the access database, then export it to XML, then upload it to my web host. I would then somehow connect it to my Visual Basics login form (Which I have already made). If this can't be done, having them register through the form and having all the allowed codes on the internet (So i can easily edit them)!
I am working in Windows 7 Home Premium using MS-Visual Basic 2010 Express. I am having difficulty connecting to an Access 2007 database using ADO. When I try to connect to the database I get the following error:
Error Code: -2147467259
Exception: [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application

There were several reference to compiling the program using x86.
Go to Project menu -> Properties -> Compile tab -> Select "Advanced Compile Options" -> Select "x86" instead of "AnyCPU"
I followed the path and there was not any option to select x86 in VB 2010 Express.
Only my local dataset updates when adding, deleting or editing records.The Source Database is supposed to update on issuing DataAdapter. Update(dataset )However, when I check my source database after running the operations it remains the same as the original.
i have a basic form in vb using .net framework 3.5,when the save button is clicked, it should update the data from the form to the access 2007 database,however, the whole thing runs up to the point in bold,
here it says that "The ConnectionString property has not been initialized" Private Sub Holiday_BookingBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Holiday_BookingBindingNavigatorSaveItem.Click
I'm new to visual basic 2010 ultimate. I want to make a search button to "search" ms access 2007 database for specific data and display the results in datagridview. I also want to display the data to textboxes.
I am trying to learn how I can enter data into a Microsoft Visual Basic 2010 TextBox on a form and when I Tab to the next TextBox, the data from the first TextBox is automatically appended to a Microsoft Access 2007 table. For this question, no other controls or objects are necessary.
I posted this as a bug on MS Connect and am wondering if anybody else can verify the problem: I been beating my head against the wall for about 3 days and I don't think it is my problem.
Desktop computer - Vista 64 bit Portable Computer - Vista 32 bit vb.net 2010 express on both of them
I can not establish a connection to an Access db (either .mdb OR .accdb) on the 64 bit computer. When I try I keep getting a message that says "Format at the initialization string does not conform to specification starting at index 0." (this was typed not copied). (There are screen shots over on Connect).
I can establish a connection to a "Microsoft SQL Server Compact Edition" (.sdf) database on the 64 bit computer.I can estabish a connection to all 3 types on the 32 bit computer (.sdf, .mdb, .accdb).The 'funny' thing is that if I establish the connection on the 32 bit and copy the program directory over to the 64 bit, the prorgam loads and seems to run fine. But the %$# _(%* Wizard will not run on the 64 bit machine. Runs fine on the 32 bit but not on the 64 bit. Of course I make sure that the db's are in the location where the program expects them to be when I run the program on the 64 bit machine.
One final thing, when I am in the progam created on the 32 bit and running on the 64 bit and I try Data->Add New Data Source->Database->Dataset only two of the three connections show up while all 3 show up on the 32 bit machine. Also the connection string is incorrect for the non-sdf connection. It should include
I am brand new to VB. I am using VB 2010 Express. I have a MS Access database and can read & display the data. However, when I enter a line of code to manipulate the data I get a "read only" error message in the project editor. I have checked the file and directory structures from windows and the command prompt. I have even used the "attrib" command to make sure the file was not read only. Then I put the following code in the form and it dispaly the read only message.
Dim infoReader As System.IO.FileInfo infoReader = My.Computer.FileSystem.GetFileInfo("C:zzz-devaccesswhitneywhitney.accdb") If infoReader.IsReadOnly = True Then MsgBox("File is readonly!") End If
I am using the VB 2010 Express DataSource to connect to the MS Access database and not a connection string in the program.
For years now I have been using access as my database. But with the SQL server Express version around I have been wondering if it is not better to use this instead of access. Note: I only develop applications for small businesses and a limited set of users. So what do you guys prefer and recommend?
I'm using Visual Basic Express 2008 to create an interface with a order database in MS Access 2007 (.accdb file). Everything is fully functional except updating the "Inventory" table is very slow. Updating around 2200 items takes almost 2 minutes and the window will appear as "not responding" for the duration if you click away and come back. Here is the process:1. Tab-delimited text file is picked by user, which includes all inventory items (not just new ones)2. Each line from text is parsed and read into variables (tempSKU, tempItemTitle, etc.)3. Old items are updated and new ones are added. -> This is the bottleneck
I used to have a series of IF statements to check which elements were changed and report them, but that was about 2x as slow. The new code is a little faster but doesn't provide the feedback I liked (update part is commented around):
Private Sub btnImportInv_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) andles btnImportInv.Click Dim strName As String
