I have an array of structs and each struct contains values for the checkboxes. I am trying to display the checkbox values contained within a particular struct.
MyStruct is an array of structs which has a values for the checkboxes
ChkBoxCol is the collection of check boxes for the form.
I am iterating through the collection as follows:
[Code]...
What I am noticing is that if the check boxes are checked in order (checkbox 1, 2, 3, 4...etc) the code works fine and the values are displayed correctly in the form. However, if the check boxes are not checked in order (4, 5, 7...etc) the code does not write the values of the check boxes and instead keeps them blank. I just need to display the values for the check boxes for a specific struct.
I am working on a way to change either the x or y value of a point and am getting an error while doing so. the code i am using to do this is the following:pts(currentNo - 2).X = pts(currentNo - 2).X - 10pts is a list of Points and currentNo is merely a count that im using to track where i am in the list. I am getting the following error
i have 5 checkboxes in webform and textbox1... when i search the record using the date specified in textbox1 when i enter 11-Dec-2010 in Textbox1 and click on submit button then checkbox1, checkbox2, and checkbox3 will be disabled and unchecked .....
I have a ListView with Checkboxes in vb.net and what I want to do is when the user check the checkbox, the program ignore the response of the user in checking the checkbox, instead it leaves the checkbox uncheck.
I created 10 checkboxs dynamically. I am using DataGridView. According to Checkbox Checked the corresponding data will display in the Datagridview. How can i connect checkbox to DataGridview. Example: Assume Each Checkbox have one subject. like English,Maths,Physics,Chemistry,Arts..... If i click English Checkbox then Corresponding Students list will show in the datagrid. when i checked Maths , corresponding students list will show in the Datagridview. How can build the code to develop this???
I have a form that creates a row of checkboxes depending on the type of analysis the user wants to perform on the incoming file. I need to be able to determine if the checkbox is "checked" but I don't know how to do that when the controls are created at runtime.So right now I have a loop going through all the controls on the form and selecting the appropriate case: for instance chkbox1, combobox1, etc. Now I can access the values of the control by using Me.Controls.Item(chkbox1) but after that the only thing resemebling checked is .Text which wouldn't be accurate. how do you workaround the .Checked property of a checkbox when it is created at runtime?
I have a form in an application that I'm building and in it I have a datagridview that when a user clicks a checkbox on a line in the datagridview and "submits" the data, then the form will insert all of the data on that line (along with the code "Holiday") into a database. Currently if I click in the checkbox on any line other than the first line and put a line break on the "Try" statement, and then fire the submit_onclick event, I'm never reaching that break point but if I click on the checkbox on the first line and submit that data, that works and it behaves at I stated above. Here is the code as it stands currently:
Code: Private Sub holidaysaveButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles holidaysaveButton.Click For Each dr As DataGridViewRow In DataGridView1.Rows
With this code above I would like to retrieve the data values, like sex, to checkboxs. So If the value of the field in database is "Male" my checkbox4 must be checked, case else checkbox3 must be checked.[code]...Retrieve Data Values To Checkbox?
I have 50 checkboxes for 50 american states. The user can choose all 50 or only 1( so basically any number he wants). Based on his choice, I want to insert or update the table in sql server 2008. e.g- Color = blue and chk1=check, chk2= check and chk3 = check (chk = checkbox).
Now the user wants to ad 10 more states to this or remove these 3 and add 5 more. so u basically get the idea. the table in database looks like this -ID Color State_id
There is a table called states, so stateid shall come from there. so how do i do a loop insert or update in vb.net?

In my datagridview, I want to be able to change the value of comboBox1 depending on what the user selects in comboBox2 I had this working correctly, however if I move onto a new line in my gridview and select a different value in the second row it changes the previous row also.In the below code the correct values are generated in the combo boxs, however when I move onto a new line in my datagridview and choose a different value from my comboBox I get this error:
"The Following exception occurred in the DataGridView System.ArgumentException: DataGridViewComboBoxCell value is not valid To replace this default dialog please handle the DataError event." Private Sub Expenses_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.TblCompanyTypeTableAdapter1.Fill(Me.Exp_testDataSet10.tblCompanyType)

I want to loop through a databale and change the values of a specific column in that datatable.eg: the database returns Request_ID, Desc, Date and Status_Ind. The Status_Ind column contains integer values. I dont want to show the integer values to the user. I want to convert that to a string value based on the integer values returned in that columns.
Im trying to check to see if a value of a label changes over time. however I can't seem to get it right.
dim val1 as string dim val2 as string private sub form1_load() dim val1 = label1.text end sub

problem is it will only check it once after ten seconds when the timer is set to 10 seconds i need to to check it every 10 seconds becuase these values display altitude, and if the server freezes the altitudes dont change. I need to make sure they are updated and not frozen.
I'm writing a program to help me understand 3d points and how computers manipulate them to 2d. Every time I run the conversion routine in my program the value I passed to it get's manipulated even though I use the ByVal key word. Here is the code in process order , tell me if I missed something here ?
[Code]...
There is a status box for me to check one of the values :> This is the flow of what I have put together so far. The problem is once I run the program everytime I press the up key to make a call to the GetPoints method the value in MyPoint is changed to reflect the forumula in the getpoints method. I explicitly used ByVal in my variables on the method call so the values in the variable would not be manipulated. I've changed it many times but I can't seem to get the method to run where it does the conversion without manipulating the values in MyPoint. I've done similar things in visual basic .net 2003 , Now I am using the visual basic .net 2008 express edition. I don't if there is a difference in the two or some unknown bug.
My first time and first post here.I am trying to change specific registry key values (to enable fast user shutdown), but I get an error message when I try this. I will hopefully be implementing a number of the TweakUI functions, but in my own representation.
[Code]...
and I get the following error message:
"The specified RegistryKeyPermissionCheck value is invalid. Parameter name: mode" (I've changed the Security.AccessControl options but none of them are suitable)
I've only been using VB 2008 for about 4 months now, and had no coding expereince prior to this

how to disabled and uncheck the checkbox values from database fields.. if i have entry in my database records as :

I have a project due tonight and suddenly 2 of my datagridviews are acting funky while the others are fine.
I have 2 tables in an sqlce db. the first is books(id, title, copyright) and the next is publisher(id, name, bookid). I'm writing a vb.net frontend to access the data.
I have data bound datagridviews for both tables. Both have their respective ID columns hidden. The publisher dgv uses a combobox cell style to display the book title in the bookid column. So far so good.
I have suddenly run into a problem where if I have clicked in a cell on the books dgv and then click a cell on another row, the title changes to the id value. The publisher dgv also updates to show the id instead of the title.
It sounds to me like there may be a problem with the booktableadapter or bookbindingsource, but I don't know where to start looking for it. I have a 3rd dgv referencing an unrelated table, and it has no problems. The code for both the working and problematic dgvs are the same (only the control names are different).
I have a grid bound to a datatable. The grid has two boolean fields. What I want to happen is, when the user checks one field (or perhaps I change that field's value in code), I want to automatically uncheck the other field. I tried the following code, and it gives me the results I'm looking for, but only after the user leaves the row. I want it to happen when the user clicks on the cell.
Private Sub ComparisonGrid_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles ComparisonGrid.CellValueChanged If e.RowIndex > -1 Then If e.ColumnIndex = Me.FirstUseColumn.Index Then
I am reading values from a database 0/1 false/true to populate the checkbox .The databse field is 'PPorCollect'. How can i figure out why the checkbox is not populating ?
OpenSQLConnection() Dim mcommand As New SqlClient.SqlCommand("up_loadOrderID", conn) mcommand.CommandType = CommandType.StoredProcedure[code]....
I populated a textbox with the value i was reading from the database.....Interesting the value is True/False not 0/1 like i was expecting...so i changed up the above code to the below code with no resolve....
Dim PPorCollect As Integer PPorCollect = mReader("PPorCollect") If PPorCollect = False Then[code]...........
I have four textboxes that only accepts numeric data.On each box is a corresponding checkbox.I want to have a button that will get the total sum of all textboxes wherein their checkboxes are on checked state.
so i have a user form, and i want to uncheck certain checkboxes if some conditions are met, etc. the problem is, i also have instructions that are supposed to take place when the box is clicked, BUT these are done when the actual value is changed, even if no click takes place. how can i get around this? i tried to have some boolean barriers but because of the complexity of my code, theres no logical way of doing it. is there some property i can use to just change the value and not register a click?
