View 6 RepliesI'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 am trying to import a bunch of excel 2003 files all with A:H columns and they are under the same headings etc. into a table in access 2003 database. This is a module in access im making. Im using a file search to look for every file that begins with Format (which they all do ) to get at all the files in the folder path. is there a more efficient way to do this? somehow select all files in a folder? and import each to the same table in access? The DoCmd.TransferSpreadsheet seeems to take each file path individually so I'm not sure how to get each file name in the folder to import it.
I have this at the moment:
Sub Import()

Set db = CurrentDb

I am trying to load an array from an excel sheet (in xml), whic I have managed by altering some code kindly provided by Beth Massi. the trouble is that I don't really understand some of the original code, hence I cannot remove the binding to some objects in the GUI that I don't need.

I'm using Excel as a database backend to load into a datagridview.

I was wondering if there is any way to load data from excel sheet into a datagridview in VB2008 dynamically. I have looked at few data connection codes but all of them involve the excel sheet and thw workbook name. Is there anyway that I enter the excel sheet name in a inputbox and the data from excel loads into datagridview without hardcoding the sheet name. I know data can be imported using the below code, here the programmer has to mention the excel workbook name, path and sheet name. [code]I am developing a program to perform some calculations and my data is in a number of excel workbooks and worksheets. I need to be able to bring the data from these excel sheets into the datagridview to perform calculations. So I was thinking if I could mention the excel sheet name in the GUI and then accordingly the data from that particular sheet would be loaded into the datagridview to perform calculations.

I have a problem when trying to show details of XML file by choosing an item from Combobox. I have two XML files, called Employee.XML & Subject.XML. The format is like below
<Employee>
<EmployeeID> </EmployeeID>
<Position> </Position>
[code]....
The Combobox contains Employee and its Position also (eg: A1 - IT professor). When I choose an item in here, its Subject details will automatically show in Textbox (one EmployeeID can have many subjects). I cannot use Combobox.SelectItem because I already set Option Explicit On & Option Strict On. I also make EmployeeID by ascending coming up with its position. How can I show details in TextBox by using Subject.XML? I tried many methods but none can work properly.
I have in my form 2 RichTextBox , one Listbox , one OpenFileDialog and one Button . In those 2 RichTextBox I would like to load two (*.RTF) FILES .
Application Steps :
1- When I click the button , an OpenFileDialog open .
2- I choose those two files (*.RTF) and when I press the OK in OpenFileDialog, the path of those two files are written in the ListBox as Items.
3- After getting the path of those two files , I would like to load them into those two richtextboxs .
The problem is that I don't want to specify the richtextboxs names in order to load the files . What am I saying ? I.E : I don't want to use that code : "RichTextBox1.Loadfile(Listbox1.items.item)" When I debug my application : everything goes well , only when the listbox items are loaded in the richtextboxs control I get only one file loaded on those two richtextboxs. Right Now I have written these codes :
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
OpenFileDialog1.Filter = "RTF Files (*.rtf) |*.rtf"

I'm having one basic aspx script that needs to load some "plugins". Every plugin has its own settings and it should perform different logics. What i'd do in php is create a class for each plugin, load that class, pass the settings file to it and call some method on that class that would give me some output. But is it even possible in vb.net? I'd need to have multiple files with multiple classes, load those files, depending on the plugin name and call some method on them to parse that plugin's settings.
View 2 RepliesI am creating a program that uses XML files and saves them automatically when the user updates information. When I have XElement.Save("Name.xml") it saves the XML file in the same directory as the EXE. What I am trying to do is allow the user so select the location of the XML. Also is loading XML files through the loaddialog box basically the same way as XElement.Load("Name.xml")?

I have managed to get the songs from the playlist into the listbox but using the for loop above it it only play the first song in the list.
Is there some code I can use in the for loop to tell it to wait until the song is finished playing before is processes the next iteration.
this is the code i have on form load: textbox1.text ="C:Documents and SettingsOwnerDesktop"
here's the code to load the listbox:
ListBox1.Items.Clear()
Dim filepath As String = (textbox1.text)
My.Application.DoEvents()
Try
For Each file As String In My.Computer.FileSystem.GetFiles _

now what this does is load the files w/out the file path or extensions , but, it loads the files in the subfolders as well . i just need the desktop files to load in the listbox, not the subfolder files
