I think the problem arose because of Windows 7, but when I was at school the program worked. The program fills in the text boxes with information from Microsoft Access. However, my laptop has Windows 7, and when debugged, the information doesn't fill in the text boxes like before. Also, for added information, the school's computers run with Windows XP.
View 2 RepliesSeveral times av been come across of the need of how to create new variables on my application while is running and the next time i will run again the application to be existed in my source code and still be inside.
what excatly i mean is for example i have a listbox with out assigne it in any databound ,or retreive any items from any textbox i just want to insert some items inside
if i go from the designer then i can succesfully add any item i want and they will be there as i declare them.but if i want to to that programmatically i will be able to add them in the listbox but the next time i will run it again it will be lost.until i will select the command again to fill my listbox which is not what i want
in my case i have a datagridview which is running SQL querys and i want if the user selects to save this query i want from some way to save this query string in my listbox . and i want to be there the next time i will run my application with out using any text file or database,
is there any way to that ? i have search before i ask but obviusly my keywords dosen't much with what i was looking for
I have a listview control that contains 2 items, ProdCode and ProdName. When the user clicks on the Prodcode, I would like the Prodcode to be entered into a field on the form. at the same time, the ProdName should populate the ProdName field on the form. Below is the code to get the data for the ListView.
Dim objListViewItem As ListViewItem

I am wondering is there an easy way to fill up text boxes. Lets say, i have a form with 11 text boxes. User puts a decimal number in one text box, hits button and that decimal number becomes converted to binary and i need to fill up all 10 other textboxes with elements of that binary code. My code looks like that:
Dim a As Integer
Dim s As String
Dim aa() As String

I have successfully navigated to the page I want and now I need to know how to fill in text boxes on the page. I used SendKeys.Send before but that was when the first box was already selected. I can't seem to get the box selected by tabbing at all. I can find the textbox id if that helps.

View 4 RepliesI have a problem in that I have five text boxes pertaining to a customer/client, where there is a txtbox for each: Name; Address; City: State; Zipcode. Of course all the txtboxes are "" at initialization. I also have 2 combo boxes and a 2D array for prices which I have finally been able to understand the array logic. I have also been able to do my necessary calculations for.
My problem. The customer information is first to be validated as all being strings and not empty. The combo boxes I was able to get to tie to my 2 dimentional array and get good output and calculations for a finished product. I am just having problems with the error messages. Also I don't want summary totals unless the data is valid. In other words, the user must enter a complete address and make decisions about the two combo boxes, both of which are needed to use the price array. I will change the comboBoxes to represent dress sizes,"S" "M" "L" and "XL" and the other combobox to describe colorRedSatin or colorBlackBroadcloth with a two dollar difference in price between them. 'That would be similar enough to the problem I need to solve.
Basically I do not want any numbers to appear for price of the dress or addons to the dress unless all validation is complete. I do understand how the radio objects work for discounts and check boxes for accumulating accessories. The program should not give any totals untill the user has input all customer information and made decisions about input from combo boxes and selected calculate from menu. Right now it calculates and puts zeros in when choices are not made from the combo boxes by the user. It will include correct amounts for radio buttons and checkboxes if anything is entered. I need error messages for customer inputs and combo box inputs (if not selected from list of option in drop down for choices) (basically if nothing was put in a text box, the text box is empty. Of course the problem is the user must enter something in all 5 textboxes and not get multiple error messages in rapid succession to fix. We can't always count on our users putting in good data.. When I tried a Do While False with ORs I was getting endless looping. I could not get it to work because it will never execute because the control never passes back to the user.
I don't want to list a series of If/Thens becauser the user will see about 7 messages, where he/she only needs to be fed one at the time. I hope someone can give me some direction. I just need guidance on how to validate the text boxes and combo boxes. The code is analyzed with a "Calculate" on the menustrip. I would like for the calculation not to calculate and put outputs into the summery text boxes unless all textboxes are filled and combo boxes are valid for all the customer information and combo box choices for my two combo boxes describing what is needed for the order to calculate. There are also the radiobuttons and checkboxes, DIMs, Const, Variables, but not having problems with that part I have my indexing problems on the combo boxes worked out also, so I am not concerned about those now except for getting the error messages when I should. I hope that I have described my issues fully. I am using visual studio 8 with Windows 7
I have code which saves DGV contents including check box columns as a comma separated text file. I also have correct code which will take the text file and re-insert it into the DGV at a later time. This all works.When I'm working on the DGV, I have this
Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged
If DataGridView1.Columns(e.ColumnIndex).Name = "Column12" Then[code]....
So that when the check box is true, columns 1 and 3 turn different colours, and when false, go to a yellow colour.However, when I "re-insert" my DGV info from my text file, the check boxes come back correctly - as true and false on the right rows - but columns 1 and 3 don't change colour. I've tried a "DataGridView1.Refresh" option but not getting it to work.The DGV is unbound. I need it to recognise which check boxes are true and update automatically when the information is opened from a text file.
My website allows users to type a code into a textbox. If a recognized code is entered, the page will refresh and display a welcome message to that user, otherwise an error message will come up. I am putting their manually entered code into a session so that their name can be pulled up. I can't get the session to stay between pages.
I have been told to make sure EnableSessionState="true" but that doesn't work on master pages.I've been told to check IIS settings, but I can't because I don't have permissions to it. Tried SessionState cookieless="UseUri" and somehow that created a never-ending redirect loop.I have debugged the functions and they DO return values. The textbox DOES go away when I enter a code and the welcome message gets displayed with the user's first and last name, so I know that works.I've checked to make sure there is no Session.Abandon code anywhere in the site.
I added a Watch to every instance of Session("IB") on the page and they are filled correctly when I enter a code into the textbox. Then when I click on a link to move to another page, the debugger stops on the very first line in my Page_Load, Dim ib As String = CType(Session.Item("IB"), String) and all of my watched IB variables immediately turn into Nothing.
Here is the code behind for the master page:
Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.OleDb
Partial Class MasterPage
[code]....
More:sessionState has been changed and the site still acts like it has been, the ConnectionString must not have anything to do with the problem with the 2nd database losing it's session. It's gotta be something in the code behind, I can't think of what else could be wrong with the web.config.
<sessionState mode="InProc" timeout="20"></sessionState>
We also found out that the session variable is still there, it just won't display the user's information when it's connected to the back up database connection.
I currently have an old database that has tables for requests and customers. This information is currently displayed in ASP.NET
What I was required to do, was to connect a new database for users into this system, while keeping the tables for the requests in the old database. Thus it is using 2 databases. I have set it up so, when a user creates a new request, in the request tables it saves it with his userID from the new database, but when the table is being displayed, it uses this new userID to find the user information from the old customers table. Thus I ended up with this:
Sub BindDataGrid()
cmdoledb = New SqlCommand("SELECT r.customerid, r.RequestID, R.RequestDate, R.RequestDescription, a.AssignedTo, r.Urgency, r.ExCompletionDate from tbl_requests r, tbl_assignedto a where r.statusid = 1 and r.assignedtoid=
[Code]....
Currently it displays nothing, and gives out an error for myItem.Value = rdr.GetInt32(0) being a Null. I went through it step by step and it loads customerids normaly into the myItem.Value, but when they run out, it is supposed to exit, but keeps going, thus giving an error.
tell me a way that i can save the stuff written in 3 text box (Name,Address,Bday) by using a command btn. And then finding all of their information by just entering Name using another button.
any help would be grateful.
please and thank u

View 1 RepliesOk, I have a usercontrol in a Class Library Projects which contains a Button, 2 Listboxes, and a Progress bar. My code is to look for a file and if its there post to one listbox and fill in the progress bar and also put the programs current task in the other listbox. Recently, I started using VB.Net 2010 Express and wanted to turn part of a form into a .dll so it would be easier to update. I started getting a error and had to declare a variable as a New instance of UserControL1 (my user control). When I did this, the control would run, but the Progress Bar doesn't fill and neither of my listboxes show anything. What Should I do?

This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.
I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.
The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.
I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.
