I have done some code to write to Excel from a String Array of 3 items. These 3 items are written to columns 1, 2, 17 or 3, 4, 17, depending on the value of the 3rd item in the array. For certain Excel files, this is taking too long to write. Is it because I'm writing cell by cell? Is there any other way of writing faster to Excel?

View 4 RepliesI need my program to check and see if it contains any of the items in an array. For instance I want the program to only filter .jpg png bmp and gif in a listbox when files are added, so I did this
If str.Contains(".Jpeg") Or str.Contains(".png") Or str.Contains(".bmp")Or str.Contains(".gif")Or str.Contains(".wmf")Then end if I want to have a a list of all these filetypes in an array or so and have it only checking in the whole array instead of typing each one.

I'm trying to use something simple this:
Dim Names() As String = {"Bob", "Bill", "Jim"}
Dim AllNames As String
For Each Name As String In Names
AllNames &= Names & " "
Next
Operator '&' is not defined for types '1-dimensional array of String' and 'String'
I guess I'm not trying to store each item in the string array correctly. How would I do this?
How can I write and read a string array to a text file?
View 2 RepliesI'm having a problem recently, a logical issue so hard to determine various examples.I need the text that is inserted in textbox, which has been altered or modified or twisted to have a proper format through line accordance and constant white spaces etc. And some cases I stuck at defining the If statement within the loop. Here's an example of a text I'm trying to reformat.[code]I'm using Microsoft Visual Studio 2010 Ultimate version with Microsoft SQL Server Management Studio. This code is being fired on mouse click event of a button control. This is a snippet of my code there are more filtering after but here is what should be changed.
View 11 Repliesbasically i have Three messages in an array Private MyArry() As String = {"This is Message one", "This is Message Two", "This is Message Three"}
I want to compare it agasint a string which is a web sites page source.If it contains one of three messages return true.
I'm close to getting this to work, but currently can't get any output to display in the listbox. I had it working, but needed to move some things around to get the join function to work.In my program, a user enters input into a textbox and an array is displayed in a listbox based on what they type in. For example, if they type in "a", all foods (in the textfile that is connected to the program) that start with "a" will be displayed.
When there is output, I need to find a way to name this array (which is created based on what the user inputs) and join all of the items in the listbox (example: foods stacked on top of each other in the listbox will be shown at the bottom as a string).I am posting the code that I have thus far; all of the errors that I'm getting (and potentially my logic errors) are just in the first public class until the end of the first if-next statement:
Public Class frmFoods
Dim foods() As String = IO.File.ReadAllLines("foods.txt")
Private Sub btnDisplay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplay.Click

I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

I have imported a sheet from Excel. It grabs the first row as the column names saves it in a dataset, and displays it in a grid view.
here is my code to do so:

Dim MyCommand As System.Data.OleDb.OleDbDataAdapter

I need to create an excel file from scratch in VB.NET given a DataTable from asp.net. I can do this for a specific file, but I don't know how to do it for a general database. That is, where I use the "CREATE TABLE ..." I don't know how to tell it what types to use for the data in the table.
The DataTable is derived from a FoxPro database. (I don't know if that matters.)
I invoke the table similar to as follows:
<%
return_value = make_excel( sql_table, excel_filename)
%>

What I need to be able to do is run through the values in sqlTable above, check their type and then build the sql to write them.
