View 4 RepliesI am having a problem, which I did not have until recenty, adding personal macro buttons to the Quick Access Toolbar using Excel's Customize function. The macros, which I know are, enabled and executable, cannot be assigned to new buttons on the QAT. Actually, I can add macro buttons to a new workbook fine, but when I close, reopen the workbook, and try to add another personal macro button, they all disappear.
I set 'Show Add-in User Interface Errors' in the Advanced tab of Excel Options and get this error when I open a workbook with personal macro buttons added to the QAT[code]...
I deleted the macros and manually keyed some simple command (msgbox 1) into a new macro and still got this error message.
I set 'Show Add-In User Interface Errors' on a remote server (where I do not have this problem) and I do not get this error message when loading workbooks with customized QAT.

I was working on a program in Blend 3; I can work on all my forms and everything runs fine in Blend, but when I opened it in VS the WFP forms would not display (I have five of them in my program and they all have the same problem in Visual Studio.), but I can run the program in VS, see the forms in run mode, and work on the code behind with no problem. I can't determine what is causing the WPF forms error in VS. It appears I have a "ResourceDictionary_4 error, but I cannot locate that dictionary in either Visual Studio or Blend.

My startup form displays a login box and then, upon successful login, displays a series of buttons. One of the buttons displays a form named Calculator using the following
[code]...
When stepping through the code after clicking the button that calls the above code, it gets Calculator.Show and then jumps to code on the Calculator form that fires when a checkbox on he Calculator form changes checked state, apparently bypassing the Calculator_Load procedure altogether.This eventually results in the following error:{"An error occurred creating the form. See Exception.InnerException for details. The error is: Conversion from string "" to type 'Double' is not valid."}With the IDE claiming the error is occurring on the Calculator.Show() line on the previous form. Clicking the button a second time causes the form to load as expected, with everything working corectly.The load procedure header is:Private Sub Calculator_Load(sender As System.Object , e As System.EventArgs) Handles MyBase.Load Am I missing something in here that would cause that not to fire first upon a Form.Show call?Possibly relevant is the fact that I renamed the Calculator form prior to the problem arising, but I've searched for the old name and there are no vestiges of code still referring to it by that name. I also tried renaming the form back to the old name, but that didn't fix the problem either. (Plus I seem to recall having ran the application several times after the name change before the error was encountered, so I don't think this is relevant but didn't want to leave it out, just in case.)

Its my first time here. And I'm a new to programming and to VB.NET too so please don't mind if I say or ask stupid things :POkay here's my question. Let's say I have a table which contains student details. (Student Code, Name, DOB, Sex, Address, Contact No) and I have a grid which shows ONLY the student code and the name.
Now What I wanna do is when you double click on a cell, ALL the data related to that particular row should be loaded into a form with textboxes.
I have here a huge csv file with millions of rows entries. I want to load this data in a vb.net application, what datatype should i use, datatable, array or sth. else? It needs to be as fast as possible. how i can optimize the loading of the data? I once loaded this data in a datatable and it took days.. then i exportet it as xml data and loaded this xml file with the data. this was about thousand times faster.
View 5 RepliesI have an xml file called "QuotesxmlDoc", in my program I have written code for a search screen that searches the xml file for titles or keywords in quotes saved and the information is then shown in a datagridview, see the code below:
Private Sub btnSearchQoutes_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearchQoutes.Click
Dim xmlnav As XPathNavigator
[Code].....
On the main screen of the program, I want to show all the saved quotes from the xml file in a datagridview, I just need to show the date, category, author, title of the quotes, I also need the datagridview to refresh everytime a new quote is saved.
Try something along these lines:
TextBox1.Text=(dt1.rows(DataGrid1.CurrentRowIndex).item(0).tostring)
where dt1 is the datatable you're using as the data source and you want the data from the first column of the grid to be shown in the text box.
