Drag&drop In VisualStudioExpress2010 Using Excel Sheets
Feb 21, 2011
I am experienced VBA programmer and I want to expand into Visual Studio 2010 (Express version at the moment, bacause it's free). What I need is some code samples to get me started. Possibly showing all relevant aspects. Here goes:
A form has products as icons (in ListView?) - ordering is done by drag and drop onto a basket Products will have color and size - selection is done by two TabStrips or similar feature ( if TabStrip control is still available in ViStuEx2010)Database might be Excel sheets if possible, but other free options are OK (if Excel can cooperate with ViStuEx2010). How about XML residing on the Web? SkyDrive?
Menu and starter of the application might be from Excel too - but I'll be glad to learn newer ways - code needed for both options: when Excel is a starter and compiled ViStuEx app. is a starter.
I imagine that many people write order taking applications using drag and drop interface.
I know that there is usually a DoDragDrop method that starts a drag and drop operation. And that there are events (such as DragEnter, DragOver, DragDrop, DragLeave) that can be handled on the target side.
Are there any events on the source of the dragdrop that will tell me whether the dragdrop operation was completed, or possibly cancelled?
I'm trying to make a program that will write and read excel docs in vs 2008 with these following editable items date, time, and results using text boxes and combo boxes but I can't figure out how to get the excel part to work in it.

I need to implement reporting.. with Excel sheets and need a lot of heavy excel workings..So..I have two options.. C#.net or VB.net !!What would be more closer to EXCEL ?What would provide me more excel api's and more control?

I wanna read all cells of all sheets/pages in my excel file and just show the text content of each cell.I have written my code but have 2 problems:
Dim ExcelConnection As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Excel.xls;Extended Properties=Excel 8.0;") ExcelConnection.Open() Dim MyCommands As New OleDbCommand("SELECT * FROM [Sheet1$]", ExcelConnection)
[code]....
1. How can I read cells inside the While?
2. My select command only selects Sheet1, how can I select ALL sheets?
I'm tryng to read an excel sheet that has more than 255 cell. I'm using the following code:
Dim MyConnection As System.Data.OleDb.OleDbConnection Dim MyDataSet As New System.Data.DataSet Dim connectionString As String = ConfigurationManager.ConnectionStrings("PCOConnectionString2").ConnectionString
[Code].....
this code throws me an error that indicates me that there are too many rows to read. I found, seaching through forums, that it can't be more that 255 cells on the sheet i'm reading.
How can i read this sheet that has over 500 cells?
I need to copy data using Vb.net if possible from one excel spreadworbook to another and place the data into the correct columns in the existing excel spreadsheet. The column titles of the spreadsheets match up, I have several templates I need to place data into and the order of the columns is different in each template so I need a way of searching for a column header in the template and then copying the data into that column.
With my Tool we are scanning excel files and generating reports. My problem is some excel sheets are password protected and getting pup-up while scanning and it halts the Tool to run further.Could someone let me know the solution, how to overcome with this problem. I just need to skip the sheet and continue with scanning without any user intervention.

I am looking for the code to consolidate multiple .xls sheets from within multiple work books in a file all containing the same format of information. Each sheet needs to be coppied to a new sheet within a single work book.
Once in a single sheet I need to then copy data from a range of fields into one consolidated sheet.
I found this code online that create a excel file and gives a name/id to the first cell of the first sheet. The excel file have 3 sheets. So how do I add the name/id to the first cell of each sheet? The code is below:
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object,_ ByVal e As System.EventArgs) Handles Button1.Click
I'm looking for a way to click and drag an item out of a listview, and get the explorer path I dropped the file on, so I can write data to that location.
i have to forms, one with a RTB on it, the other with a treeview on it.I want to be able to drag a image from the treeview over to my rich text box.Basicly like a clip art window.The treeview nodes have a short description of the image (e.g Dog) then a picture of a dog next to it. I want then to be able to drag that into my rich text box, and the picture of the dog to appear.Is there a easy way to do this?
I am trying to drag and drop items from a listbox into a richtextbox? I can not get the .DragDrop event to fire? I have copied and past the code from [URL]
I can get the .DragEnter event to fire. The mousedown event fires the drag and drop, is there something for mouseup?
I am dragging and dropping values from a listview to a datagridview cell.In the datagridview I have AllowUserToAddRows = True because I want them to drag in as many items as they need.
The problem is that when I drag an item into the new row a newer row is not created below it as it would if I had typed something int he cell and left.
I tried to add a new row on the CellValueChanged event but that inserts a row above the row that I just dragged to.
Anyone know how to trigger that event after a drag and drop?
What I want to do is have data rows on the first sheet that is basically a master list, then have the sheets behind it display the data rows that meet a given critera.For example, sheet 1 column 1 has a person's name, column 2 their phone number, column 3 their address. Column 4 has 'M' or 'F' designating wether they are male or female. I would then like to open sheet 2 and all the entries marked with 'M' are automatically produced and display all the information for each person. I also need to "change the gender" of the person and these changes are also automatically changed on sheet 2. I'm guessing it may be a combination of filtering and macros but have no idea how to execute it
I have a FlowPanelLayout that can contain several UserControls called DataGridViewFilterSortElement. These controls look kind of like buttons, but different. I want the user to be able to click one of the DataGridViewFilterSortElement controls and drag it to another position (index) in the FlowLayoutPanel. Is there a way to see the control physically moving as the user drags it to another position? In other words, is there a way to take a "snap shot" of the control that is being dragged (instead of a shadowed box) which would show the actual control moving as the cursor moves?
Also, as the control is being dragged I'd like to have the other controls position to shift automatically instead of waiting for the user to drop the drag to see the shifts. For example, let's say the FlowPanelLayout contains 3 controls and the user wants to drag the first control to the third controls position. So the user clicks and holds the first DataGridViewFilterSortElement, then drags over the second control, which causes the second control to shift to position 1 of 3, then the user drags over the third control, which causes the third control to shift to position 2 of 3, then the user drops the control in position 3.
Here is a short little video that shows what I want to do: Video Example Private Sub lblDescription_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown, lblDescription.MouseDown ' if the user left clicks and holds the element begin a DragDrop action If e.Button = Windows.Forms.MouseButtons.Left Then Me.DoDragDrop(Me, DragDropEffects.Move) End If End Sub [Code] .....
I have a treeview dragdrop event written in VS2003. It works perfectly fine when the application is running on desktop, until we move the application to Citrix. So, users are now running it off from Citrix, the DragDrop event doesn't work anymore. It doesn't even have the effects of allowing dropping.
I'm using the following code to reorder rows, it does work but i can't find a way to implement any indicator that shows me where the row will be droped, is it possible to do? It seems that the handler DragDrop is blocked until the mouse is released..vb.net
Below is a practical example of how this would be useful:A practical example would be an FTP client where a user dragdrops files to be uploaded and would naturally want to dragdrop remote files to their local folders with the intention of triggering a download of that file to the folder they dragged the listview item to.
I have loaded an Spreadsheetgear Form with 5 Taps (Sheets) in a Windows Form Application (Form2). I also have anouther windows Form Application (Form1) with 5 Buttons on it but I can't work out how to make each button open the Windows Form Application (Form2) with a different Tab (Sheet) open?
