Check / Uncheck Acording To Data Collected From A .txt File
Jun 4, 2011
I have a grid of RadioButtons, and need some help in Check / Uncheck acording to data collected from a .txt file.
The .txt file contains a list like this:
A01,a
B01,b
C01,c
A02,a
B02,b
C02,c
I have set up in a grid formation RadioButtons, and named them A01,B01,C01,A02,B02,C02. I have loaded the .txt file in an array, and want to use the first 3 letters in the array to point to the RadioButton.
Problem: How do I get the string "A01" from the array to point to the RadioButton control?
I have a txt file comprised of a vertical list. The list contains x-amount of groups but what is standard is that they are always made up three entities.Example as follows:
PANNEL A 38 2440
Explained as:
NAME WIDTH LENGTH
A list of three items (though list can contain x-amounts) is identical to:
NEW BEAM 38 2440
[code]....
I now need to create a new txt file, which is written as follows:
("NEW BEAM" is "38" x "2440") ("WOOD" is "22" x "610") ("ITEM A" is "50" x "1220")
I have data grid view with checkbox as unbound column and a button at the bottom and when button is clicked i want to check all rows in the datagrid view i.e check the checkbox if it is not checked for all rows in datagridview. If button is clicked again i want to uncheck the checkbox for all rows if the check box is checked.
Currently we are using a VB script macro created in word to create some fairly simple forms based off of data entered on a data entry form. I am very new to VB, and I have been able to create many applications using forms, but I have absolutely no history creating reports. I have been reading up on the reports, and it looks like they are designed to use with data sources like tables. I merely want to take either data from the entry form, or from data derived internaly from processing the user entered data and populate a defined report "form". I have been searching, but there is so much on printing reports, that I feel overwhelmed. I am not looking for the exact answer as much as a link or place to look for a sample for what I want to do.
Private Function Check(ByVal mytreeNode As TreeNodeCollection) As Boolean For Each node As TreeNode In mytreeNode If node.ChildNodes.Count > 0 Then If node.Checked = True Then

Using this function i can check child node when checking parent.I want to do opposite.Once i uncheck parent child also gets uncheck.It is possible using this same function.?

I have this app that can now control my browser but after I use the htmlcollection of links how can I put that stored information into a richtextbox?[code]
I use a SqlDataAdapter to fill a DataTable and then set that DataTable as the DataSource for a DataGridView. All works well. Then I add a column at the beginning of the DataGridView that will allow a user to check/uncheck a row for further processing. All works well. Then I display this to the user. All works well.
Since there are many times when the DataGridView could be displaying hundreds or maybe thousands of records, I have a button that will "Check All" records and another that will "Clear All" records. These work fine, but I've noticed a serious performance lag. Other test code that I've got shows that in an unbound DataGridView, even a large one with 50+ columns and 5000 rows, checking or unchecking all of these fields takes mere fractions of a second. (One test with 50 columns and 50,000 rows still only takes 0.334 seconds to check all of the rows.)
In my testing (with my current code), checking/unchecking 500 rows takes 15 seconds. Is this because the DataGridView is databound? If so, is there a way to UNbind it (making it simply a stand-alone set of data)? I don't need to push updates back to the server, so there's no danger in removing any databinding. I've even toyed around with this (to make the DGV unbound):
I have a checked list box having some items .When I click any item it first select the item and then when I again click it then check box is checked/unchecked How to change this behavior means I want to perform selection and check/uncheck action in a single click.
I am currently working on a Database that collects information. Firstly, i use a new windows form to collect that data. I have it set up to where, when the form loads, the database is ready to collect the information fields. And then the form closes on the button click to add that data, it does not update that data table view. It adds it once i close the program and debug it again.
Code: (Open the windows form) Private Sub btnAddNew_Click_1(sender As System.Object, e As System.EventArgs) Handles btnAddNew.Click AddNewClientData.ShowDialog()
[Code].....
Problem two: I need to make a button that will increment a cell that was set as an Int, by one, but can't figure out how to put it into code.
how to check and uncheck all asp.net checkbox on single checkbox check ?I have 5 asp.net checkbox on webform i want when 1 single checkbox checked then all checkbox will be cchecked and if checkbox is unchecked then all checkb ox will be unchecked ..

I 'm working on a quite large VB application, and recently I started profiling the memory usage, because there were some issues with objects not being collected.I noticed that the SplashScreen (boilerplate SplashScreen hooked up via Project Properties) never gets collected, because is remains referenced by My.MyProject.MyForms.m_SplashScreen. This is apparantly a private member, and I can't figure out how and where to set it to nothing with reflection code.I looked into my code to make sure i'm not doing anything special; I don't even reference the form anywhere.
If I want to narrow scope of a variable in C#, I can introduce additional braces - i.e.:
class Program { static void Main(string[] args)[code].....
In the ide, I can no longer reference y outside of the scope introduced by the new braces. I would have thought that this would mean that the variable y would be available for garbage collection.(it is interesting to note that when viewing the compiled code using reflector it appears that there is no difference with or without the additional braces)Is there any way similar to this to narrow scope when using VB.net? Does this have any impact on when variables defined in the inner scope may be garbage collected?
My application is like this : i have to search my data from database with some check box and text box when user select check box specific function go on and then when user enters some range of value in textbox then the result will shown in data grid view after that i can print it by selecting data my vb.net code is as follow:

The ToPay check box is (unbounded column) set as True by the following code in on load event;[code]What I want to do is when the checkbox (ToPay) is unchecked then Column 4 (i.e, Amount) is set to Zero.
