Make Current Tab Page Update When New Data Is Loaded?
Mar 31, 2010
I'm working on a VB.Net windows application.In the top half of the form application, I have a vendor number with a "GO" button and in the bottom half I have a list of tab pages. We have built the application to only go to the database and display data when the tab page is selected by the user. If I'm in one of the tab pages, and I change the vendor number and click the GO button, the data on the current tab page goes blank (it does not refresh). I have been told that I have to find a way of programmatically clicking on the tab page's tab a second time. How do I do that? I've tried using _Selected event, _Selecting event, _Click event. I've even tried to do a .Focus() on the tab page itself. Nothing seems to work to reload the new data without clicking off of the tab and back onto it manually.

What I am trying tot achieve is the following:User inputs data in one form that saves to the dataset table no problems. On an edit screen I want the current data saved to appear in this page within all the relevant fields but when saving I want this data to add to the dataset table as an additional line of data so the transaction records are kept.I want to add a new datarow regardless of it saving one change or all 7 changes that are possble.
e.g. Line 1 - user inputs 7 cells of data Line 2 - user amends 2 cells of data Line 3 - user amends 1 cell of data an so on. Unfortunately the terminology for certain items above may not be correct as I am still new to this programming and still on a massive learning curve.At the moment I do not have the code for what I am trying to achieve as I really dont know where to start with it.I am currently able to save the data and have it appear in the "edit" panel however only the cells changed are saved an it overwirtes the initial input.

I have an update panel that has a table in it with 4 images. Every few seconds a new image is shown. All this works but when the image changes the whole page is refreshed. I am using Visual Studio 2008 and VB.Net 3.5.I only want the images in the updatepanel to refresh. How can I do that?
UpdatePanel Code:
<asp:UpdatePanel runat="server" ID="upImgSwitch" UpdateMode="Always">
<ContentTemplate>
<table height="200px" width="100%" border="0" cellpadding="0" cellspacing="0">
<tr>

I have created a service that will update a table. <foxpro to mysql>Before the update it will delete all the data in a table<mysql> and then insert the record from the dataset<from foxpro> one by one.I have more than 5000 records and it is very time consuming, now I would like to ask for some idea if there is a way in vb.net to only insert the data that have been recently added to the table<in foxpro> to mysql table. Is it possible in vb.net to know what has been added in the table?

I have a webbrowser control and the following code is in a for next loop. If I use wba = New WebBrowser the code works in the background and I don't see the loaded pages in the webbrowser control. My question is how can I see the results in webbrowser component with wba=New WebBrowser ?
wba = New WebBrowser
AddHandler wba.DocumentCompleted, AddressOf wb_DocumentCompleted
TheLoginUrl = Items(2) & "/test.php"
wba.Navigate(New Uri(TheLoginUrl))
results.Text &= "Login to: " & Items(2) & vbNewLine

In my userform I have a WebBrowser control to load PDF files. I have added a FolderBrowserDialog to allow user selection of drives and or folders.
What I am trying to do now is after a file has been selected and viewed, the user may want to change drives and or folder locations. How do I remove the current contents of the WebBrowser control to be a blank screen (just like when the app starts, its blank).

I want to make a message box appear to show that the webpage has already loaded. I have used the code below:
Private Sub Button11_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button11.Click
WebBrowser1.Navigate("[URL]")
If WebBrowser1.ReadyState = WebBrowserReadyState.Complete Then
MsgBox("yahoo is now fully loaded ")
End If
The message box is not showing at all . I have looked for "DocumentComplete" but can't get it working ..

I'm working on a project. I want to be able to right click on a webpage and click on my custom context menu item (let's say 'screen'). What this should do is get all the page source from the current web page from where I righ clicked and save it on the disk. Basically, "right click -> view source -> file -> saveAs ", this is what i want to do programmatically.

I am using VB 2008 express and would like to know, If i can Replace a string inside of Javascript on page loaded into axWebBrowser so i can then execScript that function. The specific string i wish to replace is "_new" to "_self" this is so when i call the function it will load in the same page instead of popping into a new web browser. Also, is there a way I can just insert my own javascript function in the DOM as well?

I have a session variable that changes some things about how a page looks. I have a button that changes the value of this session variable. But ... the onClick event happens after page load, so by the time I update the session variable based on the button click, it's too late, the page has already been loaded.
Theoretically I could put all the logic about changing the display into a function and call it from page load, and then call it again from the onclick after the variable as been updated. But this is impractical: there are many user controls that check the value, used on many different pages in different combinations. I would have to hard-code the list of user controls on each page, and if someone added a new user control to a particular page, they'd have to remember to update this function, which is lame.
Is there a way to force a page reload? (I can use response.redirect back to myself and it works. If all else fails I guess this is what I'll do. But it means an extra round trip to the server, which is clumsy.)
Is there a way to process the onclick before the page load?

I have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.
I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.

I have two data tables within my data set that are loaded onto my form on form_load using statements written in code (not the designer. When I change a value for the first table via a text box the change is made to the data set. But when I try the same for the second table, the change doesn't remain in the data set when I switch to a different company and come back. I query the second table using the primary key of the first table but no code is needed when I change the values for the first table so I don't understand why the same doesn't work for the second when I change a value via a data-bound text box....
Here is my code that initially binds the data:
'This is used to read our data from the data base
Public Sub Read_Data_SQL()
Call Clear_Bindings()
[CODE]...
Here is the code I call when the selected index of my company combo box changes to have the second table reflect that of the first:
'This sub populates any information contained in the Contact2 table
Private Sub Update_Contact_2()
Dim Company As String = cmbCompany.Text.Replace("'", "''")
[CODE]...

So just to get better at VB, I'm trying to make this application that takes pictures from your clipboard and uploads them. I'm adding a label, that will tell you if there's anything in your clipboard or not, but the problem with that is that I don't know how to make it check the clipboard all the time.I'm still a beginner, so I only know how to make the app do something when a Form has loaded up, or clicked etc., but how do I make it so it checks the clipboard when it has changed? If I can't do it, how do I make it so it checks the clipboard like maybe every second. Do I need to use threads (I'm not sure, because I don't quite fully understand threads).

I'm using Report Viewer(VS 2008) to make a report in VB.net. I add Table with Table Header, Table Detail, and Table Footer. Then insert a Table Group(table1_group1) and add expression =IntRowNumber Nothing-1/10 on that group. I check page breaks at end.
When I load the report its show normal :
page 1 : page header+ table header + table detail(10 list data) + page footer
page 2 : page header+ table header + table detail(5 list data) + table footer + page footer
But when I click Print Layout Icon its show an extra page(page 3):
page 1 : page header+ table header + table detail(10 list data) + page footer
page 2 : page header+ table header + table detail(5 list data) + page footer
page 3 : page header + table footer + page footer ( this is the error)
I also try to print the report and its print 3 page.

So I currently have a aspx page that shows details for any single staff member, and the page is setup with mostly ASP labels. I have a subroutine called "getstaffdata" that populates the page on load (via subroutine).
I would like to convert this to a page that shows details on one staff member, or many staff members, one after another. So I thought of using the repeater control, but I'm not sure how to convert the page over. The staff userids are passed via query string, but I'm just confused on how to do the datasource for the repeater control.

I need some help keeping a DataGridView at the current row while being updated. I have about 140 rows of data that is being update with engineering data every 100 msec.
If the user is looking at a row 80, the slider is in the middle, when my LoadDt() runs to update with the latest data, the grid jumps back to row 1. I tried getting the first cell displayed and setting that back when done but this is not working.[code]...
