View 4 RepliesI want to read an Excel sheet into a DataTable using an OleDbDataAdapter, however, I only want a section of the spreadsheet (the part that 'looks like a database').[code]
View 1 RepliesMy requirement is to read all rows of an excel-sheet in first column that are not empty, are numeric and have a length between 15 and 20.
For example:
358218033354974
359473035499561
358218036156129
354022038366247
358218032490035
359473030516492
353210040325399
This column might have a header that is not numeric and there might be empty rows. This would cause an exception when importing them via SqlBulkCopy. So i want to prefilter the correct rows via OleDbCommand.
What I have tried so far is following(C# is also appreciated):
Using connection As New OleDbConnection(sExcelConnectionString)
connection.Open()
Dim schemaTable As DataTable = _
connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, _
New Object() {Nothing, Nothing, Nothing, "TABLE"})
[Code] .....
But this throws an exception if there are empty rows or the format of the value is incorrect. So my question is: How to restrict the rows of OleDbCommand to:
Get only first column of every worksheet
All values that are numeric
Skip empty values
Ideally only the values with a length between 15 and 20
Any way how to skip the empty rows, Or do I have to to select the whole datatable? I hoped it would be possible to do that only with one query because of performance reasons.
im looking for the method how can i copy from original sheet to my new sheet.
View 3 Replies[code] objExcelAppDataSheet is the excel application's object and strTemplatePath is the path of the excel file.This excel file is like a template that i am using in my application. In this file some cells are merged. After copying to the new sheet the formatting of the sheet does not remain same. Columns sizes are changing. Why this problems occurs? Is this MS office versions issue??
View 2 RepliesI have to provide an Excel file as an output. I have to color some of lines and make them bold.The input is based on a dynamic list (in memory) and it also could be based on CSV file that I'm already provide today (based on the same dynamic list).I'm wondering what would be the most efficient way (in terms of performance) in order to provide the colored Excel output?Should I export directly from dynamic list into Excel - or - Should I export from CSV into Excel ?

View 1 RepliesSo I've got this Excel sheet of employees which have all the information about them. I'm trying to import this info into AD, but in order to do that I need to get the username for these users as well. And I would like vba code or vb.net code that basically takes the value of every row in column D and looks for it in AD and returns the username and adds it to column A. Would something like this be possible?
View 1 RepliesI need to Store Objects with Key like:
Key: <Fontname & FontSize> / Object: <Font Object>
Example content:
ArialRegular8 | <Corresponding Font Object>
ImpactItalic10 | <Corresponding Font Object>
TimesRomanRegular12 | <Corresponding Font Object>
These font types come from an external library, the real type is DocumentFont, I prefer not to store just values and recreate the font object later, so I need to store the object, and i want to be able to call Contains() later without looping. like for example Dictionary (of T Key, T Value), is this the best option? Also, to be able to call Contains(), i will have to overload function Contains() using an Interface or this is already built-in in some Collections / Dictionaries when using a String as Key?
I'd like to use a dictionary to store the contents of an ini file. Now I know you can simply say
myArray.add("key1","value1")
myArray.add("key2","value2")
etc...
But Id like to store more information with a specific key, not just a single value, so id like to associate other values with key1 eg firstname,surname,address.
So by knowing the value of 'key1' I could retrieve the firstname, surname or address associated with it.
I know in PERL, hash arrays work in this manner
eg
$hash{'key1}{'firstname'} = 'john';
$hash{'key1}{'surname'} = 'smith';
etc....
I have been making an rpg that i have been programing to be event driven, so the last step at this point is the items... i tryed using dictionary to store all the items but this kinda failed(Im not shure if dictionary is good idea for something like this any way). well i know how to hard code the items but i dont want to do this(Event Drivien is better). So any ideas on how i could store the items?

I post a question similar to this a few days ago, but nobody answer. Now I modify my request a little bit, I want to read an excel file using VB.NET program. I know the logic below can do this. The logic is shown below.
But I have a question. This logic needs the worksheet name, but usually my application doesn't have this information, the worksheet name cannot be hardcoding. I have 2 request:Can I always upload the first sheet from the selected excel file. (ACCESS can do this without knowing the worksheet name).
