Use The DataTable.WriteXml Method To Create An XML File Without Erasing Previous Content In That File?

Feb 18, 2011

I have to generate an XML file from several database tables. I could use the WriteXml method of the DataSet to do it, but the database tables are really huge and I can't add all those tables in the DataSet at the same time or it may cause a problem because of the big amount of memory used. Then I decided to use the DataTable's WriteXml method and save table after table, but the the generated file only stores the information of the last DataTable.WriteXml's call. How can I preserve the previous XML data when adding all that information?

Drag A .txt File Onto The Txtbox, The Content Of The Text File Is Displayed In The Textbox?

Mar 3, 2012

I have a textbox on a form that is set to allow dragdrop operations from txt files.Basically you drag a .txt file onto the txtbox, the content of the text file is displayed in the textbox.All is working fine, however after the textfile is displayed in the textbox, the text box text is for some reason is highlighted.I don't want the text to be highlighted (or selected) after it's being displayed on the textbox.Second issue, after I close the file that I dragged, for some reason even if I didn't make any changes to the file, it is acting as if the file has changed.In another words, if I open a text file using my MenuItem Open item, and if I do not change the file, If I close the file it's fine it closes.However, if I close a file that I draged into the text box and then close the file without changing anything in it, the stringcompare function is telling me that the file has changed... I can't understand why.

Saving More Than One CheckListBox Lists?

Oct 23, 2011

I have 3 CheckListBoxes, and I want to save all of their "checked" states. I tried to change the code to save and load one to work for three, and this is what I came up with:

vb
Private Sub savechxlst()
Dim FileStream As New System.IO.FileStream("C:CheckedListBoxData.cld", IO.FileMode.Create)

[Code]....

Unfortunately, all this does is combine all of the checkboxes into one list (ChxLstSym), and leave the other lists (ChxLstAud and ChxLstEx) completely blank. By this I mean ChxLstSym ends up having 15 checkboxes instead of each of the 3 Lists having 5 checkboxes (Which is how it was before I saved and Loaded), though it does remember which boxes were checked originally.

Is there a way to fix this so that I can save and load the checked states for all three of the checklistboxes (ChxLstSym, ChxLstAud, and ChxLstEx) so that they are all in their own lists upon loading them?

CheckListBox Filled With Items From Array

Oct 18, 2009

I have a CheckListBoxthat is filled with items from an array. I want the user to be able to select the items they want to remove then press a button and have the items be removed from the array. I have never worked with a CheckListBoxthat before so I'm not really sure how to go about this. Here is what I have tried so far:

Private Sub btnRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRemove.Click
Dim TempNameList As New ArrayList
If cmbRemove.SelectedIndex = 0 Then
TempNameList.AddRange(NameList)
Array.Clear(NameList, 0, NameList.Length)

When I re-display the array into the CheckListBoxthat it shows that nothing was removed from the array.
