VS 2008 - Textbox Values To Be Written To The Table?
May 7, 2009
I am using OLEDB and using datareader and with the read function i am reading table to the form. But now i want the textbox values to be written to the table? I tried with the fill, but not getting.
I have a browse button that only searchs to .map files. This is my code: >>
Private Sub But_Browse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles But_Browse.Click Dim SelecteerScherm As New OpenFileDialog() SelecteerScherm.Filter = "Only .map files (*.map)|*.map|All Files (*.*)|*.*"
[code]....
When I do ok, how can I get this map file in a textbox ?
I have a question about the AddNewItem method. From what I understand, then this event occurs, the EndEdit() method is called and a new record is created IN MEMORY (or a buffer). The user fills in the form that is presented and when the Save button is pressed, the record in the buffer is actually added to the table.
In my application, a form is displayed and some of the forms databound text boxes have DEFAULT values (see the property for the textbox under the Data Bindings, Advanced and NULL VALUE). For example, I have a text box that holds a number and the NULL value is set to 0. When the form displays, the ZERO is in the text box. Assume the user NEVER enters the field or changes the ZERO to something else (which means the field is never validated).
Here is the problem. When the SAVE button is pressed, the ZERO that was the default value is NOT WRITTEN to the table. The field in the table is DBNULL. That is not the desired outcome. So - How can I check the fields in the BUFFER BEFORE they are written to the table?
I'm creating a Multiplayer LAN game in VB 2008 here is what I wanted to do I created a textbox named txtbuttons.text. If I inputed a value, for example 23856 in the textbox.The Values will be distributed in different textboxes.
example Value of txtbutton.text = 23856 2 will be distributed to txtAns.text 3 will be distributed to txtAns2.text 8 will be distributed to txtAns3.text 5 will be distributed to txtAns4.text 6 will be distributed to txtAns5.text

Can any1 teach me how to save the stuff written in the text box in the from not in a notepad file so i can retrieve it later in the same form. I just need help learning how to save the stuff written in the text.
I have a lookup table that contains a label that describes the data to be written back to my database. For example:Label = Manufacturing Repair Issue (This is what the user see's in my front-end windows app)Data = Mfg_Repair (What I want to save to the database when the user choses the label)
I tried to write a text written in my textbox to file.(a .txt). I scanned it to see if it contained any illegal characters, the program said that it did not. However, when I went to save it it said that the program performed an illegal operation.
System.Runtime.InteropServices.COMException was unhandled Message: Exception from HRESULT: 0x800A0005 (CTL_E_ILLEGALFUNCTIONCALL).
It created the text file but did not write the content of the textbox to the file.I can save the text in Microsoft word without a problem. Is there something wrong with the encoding for the textbox and how do I set the encoding for the characters so I can write it to a text file.
On my form, I'm trying to display information about a grade. I'm using a DataSet with BindingSources and TableAdapters. Using the tip from here, I'm populating the selected grade's ID, HazardType_ID and Code. Unfortunately, I want to display the the HazardType, and not the foreign key index. I've accomplished this with the following
' get the data Dim data As ProjectDataSet.GradesRow = DirectCast(GradesBindingSource.Current, DataRowView).Row ' fill in form fields

Note, I'm using VB Express 2008 (.NET 3.5) and connecting to a MS Access database.

I have a checked listbox that I've populated with a table that has three columns, Name, Address, Phone - and have done so successfully, but when i display the items in the listbox, i would like to retrieve additional values of the checked items other than the primary displayitem.[code]'we now have an array full of the Name column only, from our checked items 'i'd like to grab the other two as well (not to display in the listbox, but to use elsewhere as variables) 'and keep the checked listbox as a control in the above code, the fill_array variable is only populated with the items displayed in the checkedlistbox - my question is, can i keep the display item the same and pull the other two columns from the datasource, but only for the ones that make the checkeditems list?
I have a groupbox with a number of textboxes. I want to loop through all the textboxes, get their value( text) and add them all together and show it in a final totaltextbox outside the groupbox. This is what i have done but it does not work. The totaltextbox values do not change. Here is my code :
Private Sub AGroupBox_VisibleChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles AGroupBox.VisibleChanged Dim xxx As Integer Dim tota, ax As Integer
I have an app that reads 2 colums of numbers from a .rtf textfile. The textfile is added to a textbox line by line in a counter. Now I want to split these values to 2 other textboxes. but I don't know how to proceed now. The .rtf textfile is 2 columns of data (imported from Excel), I need this format because it is a pointpair list for Zedgraph. If I use this code both number is added, theres no split:
i used a split container, in the 1st panel, i put the textbox for the user to input the values. In the 2nd panel, i put the datagridview to output the values that the user inputted. Now, i don't know and i cannot find way how to print the values into the datagridview from the textbox.

I have a simple windows form application (I'm working in Visual Basic Express 2008). There are some forms that have simple text boxes. When somebody wants to edit something in this boxes he pushes edit button and then they are enabled. I insert some text and when I save this text is saved for good.
When I reopen the application this text is there like I want it to be. Just for information, this text is always the same in one text box, until I change it (me or some other user) - so I think there is no need for databases. For my needs this is ok because I don't need to change this data often. This is code in Form load event (for calling back the data)

I am using a string builder to set up an html table row by row so that it can be emailed. I currently gather my information from the database using a data reader and while dataReader.read, I use stringbuilder.Append to add each cell value to the table.The issue is that after about 200 rows, the html breaks and displays a cell value above the table in the email. I have tried changing the cell padding, but this was not successful.
