I have built an Access 2007 database with some data stored in it. I have managed to export data using VB2008 from that database to Excel 2007 and have it automatically draw charts based on this data and a query in the Visual Basic Code. One of the results looks like this:

View 14 RepliesThe CLR has been unable to transition from COM context 0x1b3008 to COM context 0x1b3178 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time.To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during lonunning operations.

View 2 RepliesI'm creating a database using Access 2007 and Visual Basic 2008.
I'm using the try and catch exception handler in my project. this try and catch are inserted in the Save Record button. here is the code snippet of my try & catch:
CODE:
My problem is that, whenever i add a new record and clicked the Save Record button, the msgbox "Data Update Failed" popped out. But when i recheck, the newly added record was actually successfully saved in the database.
Is there something wrong with my code? The new record is inserted in the database but why does the "Data Update Failed" msgbox was popped out instead of the "Data Saved" msgbox?? I've tried many times but i still cant figure this out. please help.
I have a table called MEMBER with fields for mem_id, mem_name, mem_addr, mem_city,mem_state, mem_zip and another table called STATE with state_id, state_addr, state_name in Access 2007.On the Visual Studio 2008 form, there is a combo box for the state. The goal here is to display the state abbreviations, but use the state_id value for the mem_state (there is a foreign key between those two fields).The mem_state is defined as number, the state_id is autonumber. Under the mem_state definition in Access, I used the lookup wizard (on the database that is in the bin/debug folder) to set the following properties:
Display Control - combo box,
Row Source Type - Table/Query,
Row Source - SELECT [State].[state_id], [State].[state_abbr] FROM State ORDER BY

History: (Do excuse me if I don't reference different methods I've taken so far correctly, I'm still learning!) I am building some search software for a law firm that I work for in Australia. It's all coming along really well, but I seem to have hit a snag getting data out of sharepoint lists and into my project!
I first attempted to add a web reference to sharepoint and after a while was able to pull in all of the data from the lists, fantastic!(OR NOT!). The issue then was when I attempted to load it up into an array using XMLNodes, whilst it loaded up fine and I could see all the data, if there was a null value in one of the columns, it wouldn't pull that null value across, therefore, I couldn't really use the data...

--I dont received an error message when i run the codes i even dont receive an exception message. but when i check my database the record was not added.
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)...
CODE:
And Here is the code for the form...
CODE:
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.

This code worked fine in Excel 2003, but since upgrading to Excel 2007 (Office 2007) it's not working. In Excel 2003 it opened the access db form and stayed open. In Excel 2007, you can see the db open, then the form, but then it immediately closes. I've checked to code and it still works fine in 2003. Can anyone tell me how to fix this? Here's the code:

i have create a software for my college which is document management. well am doing good so far up to now where i need to upgrade my database what i mean ?
in case i need to make any changes to my database i don't want to enter the database and create new table or add new fields to existing table to my current database,i would like to do that throught visual studio 2010 programaticaly. something like an additional application where i will choose my database path and the application will upgrade the database with new tables or new fields .
i would like also to ask, in order to create database,or if you already have the database and you like to just open the connection to it programaticaly and add new field ,or relate some table ,you have to work with different librarys? Like ADOX,DAO etc ? and other.?
I've create a new VS 2008 Window Form Project using VB. I added an oleDbDataAdapter to the first and only form, set it to a table in my Access 2007 Database (there is only one table, PK field autonum of course and two Memo fields). The Database is in the Project's folder. A standard oleDb Connection object was created, as I expected, then I select the DataAdapter and choose 'Generate Dataset' which produces a standard DataSet called 'DataSet1.xsd'. Now when I build the project I get an error 'Error 1 Type 'FontTest.DataSet1' is not defined.' I do have a reference in my new Project to System.Data.So what the @#%$@ is going on? Why isn't the Dataset create by the DataAdapter being recongized? I can get into the DataSet Designer. The DataTable create is perfect, three columns defined correctly as I expected.

View 5 RepliesWhat I need to get done here is not a GUI, like the SQL Import and Export Wizard, which can be run from the SQL (2000) Enterprise Manager only, but a code that I can run from within the Visual Basic For Applications IDE from Microsoft Excel 2003, maybe in the form of a module, class or userform or a combination of all three. The best that I have come across so far, was a class that first checks if the worksheet is in a database formattable condition, then creates the database, if it does not exist, a table and then transfers the data from the worksheet to the table.
I have tried the Access 2003 TransferSpreadsheet method, but that does not solve my purpose, because I want to move the data from Excel to Access, starting from the creation of the database itself.

For example, I thought I'd have to go to the references and add the Microsoft Excel 12.0 object, then import Microsoft.office.interop Once done, my thought on a simple line of code to just display the A1 box would be:
dim appExcel as New Excel.Application
dim variable as string
variable = appExcel.range ("a1").value
message.box(variable)
Running that results in an error exception. So I'm clueless. Any hints or pointers on what to do, especially how to contruct a loop to read the contents of each column in each row, process and move to the next row.
how can I let VB.Net writes an excel 2007 file?

I tried to find the solution on the Internet, but none of the codes worked for me, some people mentioned import "Microsoft.Office.Interop" in the code, but if do that in my code, VS said that "Namespace or type in the Imports 'Microsoft.Office.Interop' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases."
