DB/Reporting :: Bind These Textboxes With Current Datagridview Position?
Apr 10, 2008
On one of my forms i have a datagridview binded to an Access database. It displays only first and last names of my customers in a datagridview.What i want to do now is, when i double-click on one of the customers another form will open and display details for this customer (detailed view - textboxes).
What i have accomplished so far is that when i double-click on a customer in datagridview a form opens with details (linked to the same binding source as datagridview). But the problem is that it always opens the first record even if i dobule-click second or third in datagridview.I don't know how to bind these textboxes with current datagridview position?
How do I put a large amount of data (we are talking of a datatable with probably 50 columns and maybe 500 rows) from the access database that is bound to a datagridview in my program into textboxes depending on the row of the datagridview row I am clicking on.
What I have in the access database is countries and companies that are attached to several different dates to each company. these dates are supposed to be filled into the textboxes automatically when I click on the company row in the datagridview and also when i fill in a date in the textboxes it is to be written to the access database when I save the update.
I have used the below load code to fill my datagridview. Is there another way or can I use this?
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.TCOMHRVT2TableAdapter.Fill(Me.TCOMHRVT2DataSet.TCOMHRVT2) End Sub
I just started programming in VB.NET 2008 with the Express edition and have been having a blast so far. I thought a fun program to try and make would be an infix to postfix program.
I have five text boxes off to the side of my program that shows what is on the stack as you iterate through the equation. I'm wondering if it's possible to make these textboxes set to display what is at a certain index of a stack.
For example, if I pushed a "(" onto the stack, I would like the top box of my textboxes to update and show a "(". When something else is pushed onto the stack, say a "/", I would like the "(" to be displayed in the second box down, and the "/" to be displayed in the top box now.
I have this form filled with data using dataset, data adapter 1 Dataset , 8 data adapters Textboxes are ok and binding .. fills by 1 data adapter ComboBoxs are filled by 7 data adapters
The problem is 6 ComboBoxes data is from one table filtered by id1 i.e.: cmb1 : select id2,content from table2 where id1 = 1 cmb2 : select id2,content from table2 where id1 = 2 cmb3 : select id2,content from table2 where id1 = 3 ........ Now how can I bind all ComboBoxs with textboxes?
a table of addresses and a bindingsource for the table a enum list of address type: 0 = "Mailing", 1 = "Physical", 2 = "Shipping" etc...
I would like to bind the datasource of the combobox to the enum so it displays "Mailing", "Physical" etc. Then I would like to change the bindingsource position of the address table based on the user selection of the combobox.
Here is what I have so far:
cbxAddressName.DataSource = New BindingSource(ApplicationEnums.GetEnumList(GetType(ApplicationEnums.CompanyAddressType)), Nothing)
I am trying to develop a HANGMAN game and i need to implement a button where the user can click on it to "buy" letters. So, i designated 2 text boxes (one visible containing stars and another one not visible containing the word that should be guessed), and i wrote the following piece of code so that once the user presses the button any of the stars will turn to the correct letter. My question is, i found the index of "*" and removed it, and now i want to insert the corresponding char with this index (WordInLetters). How can i find what char is at index "index" in vb.net?
Private Sub picBuyLetters_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles picBuyLetters.Click Dim index As Integer = txtWordinStars.Text.IndexOf("*")
How do I get the current write-position using the BinaryWriter. I need to store the position in order to read from that position afterwards. (I know it would give the position where the next write would start, that will be taken care of).
Private Sub Button7_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button7.Click
[Code]...
oook so this when button7 clicked it will move my mouse to the X:700 and Y:700, but will start from the X:0 and Y:0 but i tried making start from my current mouse position but idk how not working:
i have a for loop "for each val in values" I want to within this loop some how check positions ahead of the current position for a condition. I am unsure how i can do this however apart from having an inner for loop to loop from the current position. If that is the case I am not sure how i can get the current position.I have attempted this with this code below, the inner for loop.
If creditPoints = "10" Then Dim valcount As Integer = Val.Count For intLoopIndex = valcount To Values.Cou
I'm trying to create a hook to monitor the current position of the mouse cursor. Nothing important, I just need to count some pixels during interface design and wanted to learn how to create a hook, so I decided to go for a hard way instead of a sane way.
I've found example code which declares the following function:
<DllImport("User32.dll", CharSet:=CharSet.Auto, _ CallingConvention:=CallingConvention.StdCall)> _ Public Overloads Shared Function SetWindowsHookEx _
[Code].....
But Appdomain.GetCurrentThreadID generates the warning: "'Public Shared Function GetCurrentThreadId() As Integer' is obsolete: 'AppDomain.GetCurrentThreadId has been deprecated because it does not provide a stable Id when managed threads are running on fibers (aka lightweight threads). To get a stable identifier for a managed thread, use the ManagedThreadId property on Thread."
I've tried using ManagedThreadID, but that doesn't work. The thread ID returned seems to be the logical thread ID of the thread, as it runs in the .net runtime, rather than the Win32 thread identifier.
Calling the function ith AppDomain.GetCurrentThreadID works, but I really would like to have a "stable identifier" for my thread.
Can someone explain to me whether it is possible to use ManagedThreadID in this context (I assume not) and, if not, the things I need to avoid in order to stop the AppDomain.CurrentThreadID from becoming "unstable"?
I'm using VB 2010 Express with two instance of AxWindowsMediaPlayer in order to sync two videos (the videos are of the same thing but from two camera angles). Because the videos were started at slightly different times I've manually set the start time of each one using the following
The problem I'm having is that whilst the WMP clock initially displays the above times in each AxWindowsMediaPlayer, when I play the videos each starts a few seconds out from the stated currentPositions.
The video files are around 300MB each and when testing with smaller video files the problem does not seem to happen. I'm guessing the large file size is causing some delay and hence causing the problem.
I am currently working on a VB.Net program where there are two parallel multiline text boxes like this.
----- ----- | | | | | | | | ----- -----
I would like that when one text box is scrolled, the other is scrolled as well. I was wondering if there was a Scroll event that could trigger the change the position of the scroll bar of the two text boxes.
Without using TopIndex, EnsureVisible, etc., is there a way to simply save the current scroll position of a listivew as a point, then reset the scroll position to that point after reolading the listview?
I'm currently developing an application with a reasonably complex DataGridView that allows the user to build the lines of a sales document: Quantitiy, Description, Price, etc with some additional fields to help calculate price based on cost or discount i'm sure you get the jist - all this means we're not just diplaying data but adding and manipulating it - It also means there's mainly decimal fields, nit just simple text fields
Now, i'm new to VB.net, so i've perhaps done things a bit backwards during my learning curve, namely designing and coding my DGV before creating the underlying database table and binding to it - so as i'm sure you can image there's a bit recoding to do to allow for the fact that it's now bound to a datasource.
I'd got the DGV working just how a wanted it to, but now that i've bound it to a datasource i'm hiting multiple problems with: Formating the appearance of figures in the DGV Problems with blank fields while enering data (before the i try to save the data back to the database) How the DGV is functioning - it seems to behave differently when adding lines to a new sales document than it does when adding lines to an existing sales document
And given that when saving edits to an existing line i need to provide a valid update command i'm begining to think that it might be easier to scrap the databinding altogether and just Select, Add and Edit the database with code rather than binding the DGV in the IDE
I've read various threads about avoiding databinding due to it's limitations, but i've also read that it's far better in later versions of Visual Studio and .net. and i'm using VS2010
I'd just like some advise as to whether my gut feeling is right or whether i should persevere with databinding the DGV. i've noticed some quirks of databinding while working with other controls such as text and combo boxes, but i've overcome these and the result seems to be easier than coding the data transfer manually.
But i'm really struggling with databinding the DGV and the fact that i'm dtatbinding to a seperate table to the rest of the controls is leaning me away from databinding
I have a form with multiple textboxes and I want the text from the text boxes to append to the current information I have in my dataGridView. How can I accomplish this? I have tried placing the text boxes information in a generic list but I can't achieve passing the list to my function...
Here's what I have tried: 'strPath is a .CSV file which I want to append to Public Function insertNew(ByVal strPath As String) Dim writer As StreamWriter = File.AppendText(strPath) [Code] .....
I am using VS 2008, VB.NET and Windows XP r3.I am trying to use LINQ to DataSet in my app. In my test app, I can get it to work find. My test form has an OleDbDataAdapter, an OleDbConnection and a DataSet. It also has a DataGridView bound to the one table in the DataSet, a BindingSource and a Button.[code]
I am trying to change 2 textboxes so that they show the current list view selection. When I click to change the selection the program crashes. Here is my code:
Private Sub BookmarkListing_ItemSelectionchanged(ByVal sender As Object, ByVal e As System.Windows.Forms.ListViewItemSelectionchangedEventArgs) Handles BookmarkListing.ItemSelectionchanged NameBox.Text = BookmarkListing.SelectedItems(0).Text LocationBox.Text = BookmarkListing.SelectedItems(0).SubItems(1).Text End Sub
Is there a way to bind the text property of a control to an expression? I have a user control that I add to a FlowLayoutPanel. You can see I have 4 controls in the FlowLayoutPanel below. The first control is a LinkLabel and the other three are my user controls which are numbered 1, 2, & 3. I'd like to bind the label that shows the 1, 2, or 3 to the user controls index within the FlowLayoutPanel.
If I happen to remove the 2nd user control I want the 3rd user control to now display 2. I could use the FlowLayoutPanel ControlAdded or ControlRemoved events, but wanted to see if I could do some binding first.
I am using this code at the last line of my form load. I want the position 5,5 to have the cursor set at it. It works when then datagrid is already open:[code]However, when I use it on the form load, you can see that it was selected on the datagrid, but the cursor is set at textbox1...which happens to have the first tab order on the form, even though I have acceptstabs off. Can anyone tell me why this would happen? Basically, it is setting the cursor at the cell I want, but after the form loads, it jumps to textbox1 and highlights the text.
I created a project in VB.Net 2008. i use a code to Add,Update and Delete record. It works fine. The problem is: How to get current records informations when i click in gridview or listview value.
Question: How to pass the current user on the web page from the IIS server to the Reporting Services Server.I have seen this topic throughout the forums. However, the answers are always hard code the user in web.config - use a login window and pass those fields to the IReportServercredentials or create one user for everyone.
When the person who asks the question comes back and says that doesn't work there is not answer.Does anyone know how to do this? I have VS 2008 ( and 2010 ) I am sending the info to SSRS 2005 server.As anyone using SSRS knows that if the reports have parameters and udf behind the report to inspect who the user is, then you have to pass that user to the report.

I have been programming steady with vb.net for a year now and was all happy about using the List view and email etc from web sites. I even used a reportviewer to pdf to email attach, cool. Now I feel quite lost and realize I have not been using properties, etc. That is my background.
I have a database app where on a button click, I export the current record to crystal report which in turns converts it to a PDF file. Upon application startup, I export one record into PDF just fine but when I move ahead to the next record and I click the export button, the new PDF file that was exported is now blank. If I restart the app, I can then export the one record again but any subsequent record will export to PDF as a blank PDF file.
To sum up:I can export one record once using the below code snippet but when I try it for a second time on another record, I get a blank PDF file (only the crystal report formatting is in the PDF).
How can we databind a datagridview to some of the My.Settings (user scoped) properties so the user can edit the values? This must be to a datagridview. I know we can bind to My.Settings in a form with textboxes and so on, but in this case we just want it as list of editable strings in a datagridview.
Of course some My.Settings entries can have different datatypes which complicates matters but generally we're only working with strings and booleans. Also, let's assume the user understands that he must enter the string "true" to set a boolean to true. No checkbox column needed. Here's what we are using (and it works), just looking for a better, leaner way: [Code]
