i want to create system that can search and open 1 excel file from multiple excel file.Since there are too many excel file, i create a database(using excel) which list all the excel file and sorting it by project name in which i want to retrieve the excel file through project name. this is the example database that i had create:
ProjectName ExcelFile
PA201 d:Project.xlsx
i just want to design 1 user interface,type the project name in the textbox then click command button to open the excel file but i don't know the coding.
1. I get a list of excel files from a dir into a list box and search for number by select each files at once. I want to select multiple files at once and search them one by one.May be using checklistbox.
2. The output is shown in a new window (labels) with result from that particular file. If multiple files are selected that the output should show result from all files in different labels.
3. Excel program stays open in memory after closing my application.
4. Also I cant get the app to display message "maskedtextbox1.text" not found in the sheet.[code]

I have this issue that occurs with me and driving me crazy i have a report that contains thousands of records and i need to export it to excel , but the excel normal extension .xls
is showing missing records at the end of the file , so i save my file as an .xlsx extension it saves correctly but when i open the file it generates an error
"Excel cannot open the file '<var>filename</var>.xlsx' because the file format for the file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file."but when i test the file i drag it and open it in an empty notepad all the records shows up correctly
I would like to open the excel file after create the excel file. The creating file function is done, but the system unable to open the excel file. My coding as below:
Dim xlApp As Excel.Application Dim xlWorkBook As Excel.Workbook Dim misValue As Object = System.Reflection.Missing.Value
I have an application the contains several excel files bundled with it. I'm not opening the files and processing them within my application. These files contain a data-connection to reload all of the pivot-tables within each excel file. I have a 'link' on my form, that when clicked, it determines which file to open and calls a sub using filename and executing Process.Start(filename) for any excel file I want to open. I have no problems opening any one of the files and then exiting excel.
The problem is when I 'close' a file, but don't exit Excel; then try to open another file(clicking link on form)... it creates a new instance of Excel.
I know from experimenting that the fileopendialog form will 'reuse' an existing Excel instance, IF it does not already have a file open.
How can I do the same thing without using the fileopendialog?
I don't want the end-user to have access to the folders where these files live. That's why I have multiple 'links' on my form, one for each xls that already exists. I just want them to be able to click on a link and the xls file opens AND if they choose to merely 'close' a file and not exit... Don't create a new instance of Excel, but re-use the existing one.
I've got a Form with a Textbox & a button User will type a file name into the textbox & click button.Code will search for the file in a specific folder & open it, or display message "File not found".I've used Process.Start() to open which works ok but I don't know how to deal with "File not Found"
I want that if the user of my program hits a button the other file loads, but that file is not always at the same place. I want that my program search that file and open it.
When a cell in column A changes, run a macro that will search for a file at a certain folder path (including sub folders) containing what was entered into column A. It will then open that file, copy items into the rows beside where the information was entered. So far I cannot get the search for the file to open the workbook. Microsoft runtime script is included in the references.
Here is what I have so far. Which is not working except for the first sub.
Private Sub Worksheet_Change (By Val Target As Range) If Target.Column = 1 Then ActiveCell.Offset(-1,0).Select Then
I have a form with a couple of combo boxes. The first combobox adds items based on each row in an excel sheet.
Public Sub FetchExcelValues(ByVal ControlType As String, ByVal control As Object, ByVal xlApp As Object, ByVal xlWorkBook As Object, ByVal xlWorkSheet As Object, ByVal column As String, ByVal row As Integer)
[Code]....
This basically reads each cell in the specified column until it hits a blank cell. Then it takes the value of each cell and adds it as items to the first combo box. Now, what I want the code to do next is to take the selected item from this combo box and look for a match in another worksheet. When it finds a cell that matches, it should pick up the value from column B of the same row as the match. There might be more than one match as well, so every time it finds a match, I want to pick up the value of Column B of the same row and add THAT as items in the second combobox.
I need to do a search-system from excel file. User can put some word to a textbox and then VB looks for this word from excel fail from first column and if it finds, then it writes the corresponding value from next column to a label.
I got so far this:
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim oExcel As Object = CreateObject("Excel.Application")
[Code].....
but on that underlined if sentence it gives error "Object reference not set to an instance of an object". Without that if sentence it shows the value, but I would like that it finds the right one.
Path = "C:" For Each FoundFile In My.Computer.FileSystem.GetFiles(Path, FileIO.SearchOption.SearchTopLevelOnly, "FILE*.10") _ And For Each FoundFile In My.Computer.FileSystem.GetFiles(Path, FileIO.SearchOption.SearchTopLevelOnly, "FILE*.09") 'do code
Next My goal is simply to search for multiple file extensions. I cant use FILE* as my search parameter as this returns other files e.g FILE2012.10z which i don't want.
I am needing to open up a file, it is a kml file, and I am wanting to search for a particular line and the replace some of the lines following that.
Dim file As New System.IO.FileStream(kmlFileName, FileMode.Open, FileAccess.ReadWrite)But I don't see any means in which to actually go through the file line by line in order to search for my criteria.
I'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.
Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.
I need to open an excel file from vb.net and then search it for specific data. I then need to take those data and insert them into text boxes on a form that i have created. This is all controlled by a button click. I already have some code that will open a file dialog box and let me navigate to the correct file, but I am having trouble with the search portion. I have tried the Find function but I am not sure of the proper syntax. I am using Visual Studio 2008 and Excel 2003.
I have written an access application for project management and am trying to convert it to VB so i can make an exe. what i need to do is open an excel file because my gnatt chart creator is an excel document.When i run my debugger it says it doesn;t know what the open command is..I think i need to include a reference but do not know which one and there are lots to choose from. i have included the excel reference so the compiler knows what an Excel.Application is and what Application.Workbooks is. but when i try and go beyond work book i get no options like open or save or saveas or worksheets.[code]
The following gives me an error when I try to open an Excel file if the value of lblFileName is different than the file on disk by differences of upper or lowercase letters.
Im struggling on how to open an excel workbook without one of two problems.
1. After the first workbook is opened and I close the workbook, if another is opened the worksheet area is "transparent", as in, you can see the desktop or any open app behind excel.
2. Closing excel and opening another workbook after X times (4+?) via the vb.net app I use causes the computer to reboot.
I am stuck thinking it is the method used to open excel within the app.The code below has two methods, both produce the same affect. One method is blocked (makes it easy to test either one).[code]I have two buttons that open workbooks, both have identical code less the workbook requirements.Is there a better or best method to use for opening excel workbooks from vb.net?
I've been trying for a while to declare or to open a excel sheet in vb.net. I already read excel file in vb.net and other links but it doesn't work. I added Microsoft Excel 12.0 Object Library. I included:
On my computer I've VB.net 2005. and also office 2007. I try to open an excel file like that
Imports Excel = Microsoft.Office.Interop.Excel Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles Button1.Click
I am working on a VB.net program that must get data from excel workbooks. I open the excel workbook, copy a chart image tp the clipboard, then copy the contents of the clipboard to a PictureBox.Image. The problem I am having is the files contain links to other workbooks so when I open them I get a message box asking if I want to update the links. Since this is ment to run automaticaly at certain times I will not be there to click on Yes or No.I also have a similar problem when I try to close the workbook. I get the messagebox for saving changes to the file.Here is the code I am using:
Dim objXLS As Object = CreateObject("Excel.Application") Dim FileName, Sheet As String Dim data As IDataObject
[code]....
objXLS.ActiveWorkbook.Close()'This is where I get the file save changes message boxI am using Visual Studio 2008 Pro and excel 2003My operating system is XP?
