I have to do some maintenance on an old VB.NET application (Visual Studio 2003) that uses Infragistics NetAdvantage 2006. I have a UltraCombo control binded to a DataView.
How can I refresh the content displayed after a change in the database?
I have a Label, whose content is displayed by a while loop.when i display a text in label, it displays correctly. sometime minutes, the same text displayed in the same label, and the size of the text in the control changes.
Here is the code :
//Form_Load :
Thread t = new Thread(displaySentences);
t.Start();
//display sentences:
void displaySentences()

I want my application to open a web page that has an iframe within it named "test_iframe". Now I want to obtain the text being displayed in test_iframe. How do I get this content (I dont need the HTML code, only text being displayed in that page). Also if the iframe is hidden, can I obtain the content in such a scenario also?
View 6 RepliesI have a main page that loads a content of a div:
var content = $("#content_layout");
//some code here
content.load("claim_form.aspx?claim_no=" + file_number);
The claim_form.aspx has a drop down, and based on that drop down it should show the apropriate input fields. I set the index to be 1 and automatically load the first set of inputs. Here is some code to explain it better:
$("#request_type").change(function(e) {
index = document.getElementById("request_type").selectedIndex;
if (index == "0") {

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.

i am currently making a project which is to make a cinema screen booking system. My main problem is that although i have most of what is working i need to find a formula to give the full result (overall price) in a label. My other problem is the fact that when i interact with my form certain things dont auto refresh when i change certain values e.g i change number of seats but it doesn't auto refresh the price or anything OR i click one discount then another but nothing changes and it keeps the old value.
Okay in my menu i have a CombBox (ComboBoxScreen) for choosing the film and there are 3 films to choose from in the drop menu each with their own price. I also have a Textbox (NumberSeats) for inputting a number of seats you want to book for chosen film. And lastly there are 3 radio buttons each with different discounts. e.g No discount, 10% off and 25% off. A formula to work out the overall price uses all three functions/tools above. [Code]
I use Vb.NET from VS 2010 I use a SQL File to run a script, when changes to the database should be done.This works fine for me. The SQL File is in my project and marked as embedded file.Now I run into an issue. I have to change the user name, when updating a Trigger or SP (for complete information: I use mySQL and 3rd Party Script component)So, I thought, I write the embedded file into a Temp-File, make the changes to the file, run the temp file through the script component and then delete the file.

I have been trying to work out how to change the content of a picture box using a context menu. The idea is that the user would have a choice of three images which are saved in the resources file to change the main picture on the form. Is this possible?
These are the few options that I have tried from looking around on the net:
Private Sub ButtonImage1ToolStripMenuItem_Click
(ByVal sender As System.Object, ByVal e As System.EventArgs)
Handles ButtonImage1ToolStripMenuItem.Click
PictureBox1 = (My.Resources.button1)
End Sub

None of these have actually worked.
I am using the FormLayoutPanel for the first time and I am not able to figure out what is going on.On the form, I have a label that can grow and shrink because the content can change. The text includes the name of the client and that name can always be different lengths in regard to characters. I also have a grid on the form.
As you will see from the attached image, the form that has the FormLayoutPanel on it is showing small and not showing the content of the form. The form is indicated via the green arrow.In regard to the FormLayoutPanel, I have set it up in the following way:
Three rows, one column.The label is in the first cell, nothing in the second cell and the grid in the third cell.The TableLayoutPanel is anchored top, left, bottom, right.
Autosize = True
AutoSizeMode = GrowAndShrink
The Label in the first cell is anchored top, left, bottom, right TextAlignment = MiddleLeft
The grid in the third cell is anchored top, left, bottom, right and also Dock = Fill

I have a ComboBox which content might change. The issue is when the content is changed, 1) i lose the previous selectedIndex, and 2) SelectedIndex is set to -1. I would like an MVVM solution, not some solution involving code-behind. I can have the SelectedIndex set to 0 on content change, but -1 is not a valid value for my model.
What i did as a 'trick' was to have the setter of the property bound to SelectedIndex to set the value to 0 when the value is set to -1. So now i don't have incorrect value in my model. But the ComboBox does not display the "0"th item, rather an empty box.
What could i do to have my ComboBox display the first item (index 0) when its content changes ?

I am using a DateTimePicker to allow the user to select dates between which, info from a database is selected and displayed in a DataGridView.This works fine exept that the dates selected by the DateTimePicker seem to bring back results in US date format!
If I do a debug.print (DateTime1.text), the date is in UK format i.e 11/05/2009 but when these variables are used in a Select statement, the dates returned seem to be in US format e.g. selecting dates between 01/04/2009 and 7/05/2009 selects dates between 04/01/2009 and 05/07/2009 when the results are displayed in the DataGridView!

I'm in the process of making 2 database applications. Each are encountering their own set of errors. For this particular application, I have a "Main Menu" form that has a button which loads an "Add Record" form. The user is suppose to be able to insert new records here via text boxes, but the problem is that record with the first primary key is being displayed in the text boxes when the "Add Record" form loads. I have no idea and can't find anything anywhere about making these boxes blank. I'm connecting to the .accdb through a dataset.
View 5 RepliesI'm using ASP.net; I have a popup browser window that contains an databound gridview with textboxes. It has an "Add to Order" button which takes the values entered and updates the database, then closes the popup and refreshes the parent. This currently works perfectly using window.opener.document.forms[0].submit();self.close(); in a RegisterScriptBlock
I now need to update the database on gridview page chage so that textbox values are not lost. I put window.opener.document.forms[0].submit(); into the PageIndexChanging event of the datagrid, but it does not refresh the parent window. Refreshing the parent window with the order lines helps the user see what they have already ordered. My update database method runs fine, just not the parent browser refresh. I also tried "window.opener.location.href = window.opener.location.href" to no avail.Refresh parent browser window on GridView page change?
I want to be able to hide the left hand side of the screen and right hand side of the screen at the beginning of the program.
Then when the user presses create new button the left hand side of the screen becomes available so they can create the new item. Then when they press save it comes back to the middle datagrid only.
Then I want to add an event when the double click on the datagrid row (data is programmed in to the datagrid in the code) the right hand side of the screen becomes visible then when the button allocate is pressed the right hand side disappears again just leaving the datagrid.
I'm having a problem with my software.
This is are the parts of my system where my problem occurs:
- Search Button
- List Box1
- TotalTextbox
- Button
- SQL Database with a Column named "Amount" and it only contains numbers Datatype is System.String
So, basically a user clicks the Search button and searches for a data in the SQL Database, and the result of the search displays in different Listboxes including the "Amount" Column from the database, which has it's own Listbox named "Listbox1". the Listbox is now filled with numbers.
Goal: The goal is to get the Sum of all the "Numbers" Displayed in the Listbox1, and the Total is then Displayed into a Textbox via using Click event or automatically.
The Code:
Dim sum As Double
For x As Integer = 0 To ListBox1.Items.Count - 1
sum += CDbl(ListBox1.Items(x))
Next
TotalTextBox.Text = sum.ToString
And i got this Error: Conversion from type 'DataRowView' to type 'Double' is not valid.
I ended up with this..
Dim sum As Double
For x As Integer = 0 To ListBox1.Items.Count - 1
sum += Val(ListBox1.Items.Item(x).ToString)
Next
TotalTextBox.Text = sum.ToString
But the values are not adding up, the total is always at 0. i've been searching for hours now from the net to a better way of doing this.
Here's a quick Flow on what im trying to accomplish here. Record from Database -----Displays on---> Listbox1 -----User Clicks--> Button1 ----Displays Total sum on----> Textbox1
I'm having a problem with my software. Im totally new to Vb.net and only learning through ebooks and google.This is are the parts of my system where my problem occurs:
- Search Button
- List Box1
- TotalTextbox
