View 1 RepliesVS 2008 : Updating A Data Base File Via A DataGridView Control When Called From Another Form?
Jul 24, 2011I am sorry to keep bothering you about this damn DataGridView control ... As you might have noticed I am having a hard time with the DataGridView control ... My latest problem has to do with updating the data base file (Access) through a DataGridView control .
Up to now I have managed to successfully edit an entry in the DataGridView control and moreover to successfully update the data base file itself .
The above form and its code work fine . The problem starts when I am trying to run the code of the Update button from another form .
You see , I have another form , through which I change the contents of some of the cells in the DataGridView control (back in Form1) . What I want next is to simply update the data base file itself , just like I was doing with the button in the first form , after I manually changed the cell in the DataGridView control .Thus , on the second form I have a button with this code :
Form1.Button1_Click(Nothing, Nothing) (of course the Click event is declared public)I have also tried :
Form1.Button1.PerformClick()
but still nothing ...Although Form2 successfully changes the cells back in Form1 , the data base file itself does not get updated ...If I manually press the Update button in Form1 I once again successfully update the data base file , but I want to do the whole thing by calling the Update button from Form2 .

View 25 RepliesBinary -store/retrieve Bit Data From File Using BinaryWriter?
Apr 11, 2012I need to store/retrieve a bit from a data table of 3.268.760 bits long.
Using w As New BinaryWriter(File.Open("test.bin", FileMode.Create))
for x = 1 to 3268760
For i = 1 To 3268760[code]....
the w.write(?) stores a boolean value meaning 0/1 for false/true values, but Vb.net seems to use an whole byte to store this data which is too expensive for my table (3.268.760^2).Is there a pratical way to store/retrive single bits from a file using vb.net? (meaning as little as possible conversion to other types).

Can Store Data Annotation Error Messages In An External File
Dec 17, 2010I am using data annotations to validation my class properties. A requirement has emerged to store the validation error messages in an external file from which they would be loaded into memory at runtime.I thought I'd be able to load a colleciton of error messages from an XML file and then set ErrorMessage:=[StringVariableHere] ... but apparently that doesn't work as you need to use a constant value.If I store the errormessages in a Resource.resx file then those error messages are compiled into the project and can't be loaded at runtime - or am I wrong?
View 1 RepliesVS 2008 Finding A Specific Row And Specific Columns In Data Base File (Access)?
Jul 24, 2011I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .
Program A Simple Web Browser That Can Search For Keywords And Store Relevant Data In Another File?
Aug 19, 2011Hi, I need to program a simple Web Browser that can search for keywords and store relevant data in another file.I am facing a problem with authentication, mainly cookies and maintaining a session.So I read that Web Browser Control is based on I.E.? So may I know how are cookies and session handled?Do I have to implement them manually or are they stored and retrieved from the same folder as the one used in I.E? If so, if I delete the I.E.'s cache, am I also deleteing the cache of any Web Browser I make using Web Browser Control?

Mar 22, 2012I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate.
