Convert Ms Access Data Into Pdf In .net?
Mar 9, 2010
I want to convert the ms access data into a document so that the print function in vb.net will read it. Where do I start from here?
Here is my form:[URL]And here is the code for print preview.
Try
PrintPreviewDialog1.ShowDialog()
Catch es As Exception
MessageBox.Show(es.Message)
End Try
How do I incorporate the above code, to the code below so that there is something that can be seen when I hit the print button?
Dim cn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:search.mdb")
Dim cmd As OleDbCommand = New OleDbCommand("Select * from GH where NAME= '" & TextBox6.Text & "' ", cn)
cn.Open()

I just made a code to convert data from excel to access.
I encounter an error every time that I try to make the convertion.
This is the error:
'Sheet1 $' is not a valid name. Make sure where this does not include characters or punctuation marks are not valid and does not too long.
I have to mention that I have Office 12 (2007) that is not in English!
Public Function xls2mdb(ByVal xlsFileName, ByVal mdbFileName) As Boolean
Try
FileExist(mdbFileName)

I download a file into access. One field contains one to many numbers always separated by a colon and a space: I have no control over the download. TheNumbers have a 1 to many relationship to a customer. Each number must then be verified against two separate reference files, and if the numbers match the description related to the number will be displayed.I'm just learning visual basic. I've made the changes manually (yuk-this took forever); I've tried various string/conversion commands; I've taken the data and placed it into excel and tried to manipulate it, without success.In this case is always numeric. In another field, similar problem, it's a combination of text and numbers.
Example: Cust# TheNumbers
99 1234; 12345678; 123123; etc...
88 87654321, 345654, 98989898. etc..
The numbers can vary in length and quantity. For each customer each number must be loaded into one field.
Example outcome:
Cust# TheNumber
99 1234
99 12345678

i have done some research on converting an existing app to VB.NET, but have not found what I am looking for.
My existing app is currently created in Access 2003 VBA using access forms, modules, tables queries etc., and would like to convert all of it to VB.NET.
What would be the best method or tools to use to accomplish this? The VB.NET app would be developed from VisualStudio 2005..

We have developed an application on the Access plattform for the last 3 years. Now we see that it has grown to a size where we would like to convert to standalone program because of Access licensing demand. I have been in contact with MS about Visual Studio and gotten a price for 300pr license of VS.I also had some technical questions about VS, but there MS have a technical customer support which are to expensive to have some presale question

I am attempting to use the DateTimePicker and then add a day to each iteration in a For/Next loop. That seems to work fine and I can verify with msgbox that it is happening. However, I also need to write the date in string format to an Access database using INSERT INTO. However, when the code is ran, I get a "syntax error (missing operator)". Code is below. Can someone help please? I have tried all I know to do.(Please disregard the additional values in INSERT TO, I have verified they are working properly)

I'm a new member to this site, and I have been searching for a solution to this problem.. Although I have found variations in the problem, nothing has seemed to work for me. Just started programming last year.
I am trying to populate text boxes in a form based on information from an Access Database. Everything is working, except when there are empty field values; the program then crashes because a DBNull value is returned. I set up an if statement to check the index as the rows are read for DBNull values, the problem is How do I actually change the value in the field from DBNull to a blank string ("") ?? Everything I try gives me an error, most often saying something about setting up an object. The problem happens within my if statement of the do loop...I'm thinking maybe I need to set up parameters ? Or an actual edit session within a datarow variable?[code]...

I'm trying to connect a VB application (2010) to an MS Access DB by adding a data source from the data menu but I receive this error message "The connection you selected uses a local data file that is not in the current project.Would you like to copy the file to your project and modify the connection ?
If you copy the data file to your project, it will be copied to the project's output directory each time you run the application" and the options are (yes , No , Help)
If I choose Yes I will not be able to make the application 'device independent ' since it will not be copied under the bin , and if I choose No , changes won't be applied to the DB

I have a combo box with a data source. This box shows one column of a table and allows me to select one item.Next, I have an ordinary text LABEL that I need to put text from another column of the item selected above.I tried to set the data binding field of the label, but this grabs only the first row or data and shows the selected column. That is nice, but I can not figure out how to update the selected selected ROW when the combo box item is changed.In this case the combo box lists a bunch of inventory parts. When I select a specific part, I need the change the text in a label to show the manufacturer. (like a sub-form). This same behavior will be used in several other places, but the relationships can cascade.

How would you add data source to your combobox from a combobox that is connected to the access atabase?they are both ın the same form of course and the software language ıs Visual Basic. I ve got two comboboxes that I need to connect with eachother combobox1 is showing the "itemsonsell" from the "table_items" table from my access database, the second one should show the "prices" value from "table_items" depending on which "itemsonsell" item is chosen on combobox1,I ve done the solution below,but it didnt seem to be working,it is showing all the "prices" that are under the "table_items" table's "prices" class.

I am trying to import a large array of integers stored as a csv file into a VB.Net DataTable called BeamMap. The .csv file consists only of integers, with a delimiter of ,, no quotes around the data (ie., 1,3,-2,44,1), and an end of line character of line feed and carriage return. All I want to do is get each integer into a DataTable cell with the appropriate rows and columns (there are the same number of columns for each row) and be able to reference it later on in my code. I really don't want anything more than absolutely necessary in the code (no titles, captions, headings, etc.), and I need it to be fairly efficient (the csv array is approx. ~1000 x ~1000).
