View 1 RepliesI am converting several VBA projects to Windows form applications. The only problem I have is that some of the functionality of Excel is essential to the application, such as R1C1 formulas. I do not want to instantiate the Excel application or access saved worksheets. All of the data is retrieved by querying Oracle databases. 2-Dimensional arrays are not an option because the columns contain differing datatypes, and DataGridViews are too slow to work with.
I thought simply dimming a Microsoft.Office.Interop.Excel.Worksheet object would be enough, but the program kept failing and upon inspecting the object's elements in debug mode, I found that every value says this:
{"Unable to cast COM object of type 'Microsoft.Office.Interop.Excel.WorksheetClass' to interface type 'Microsoft.Office.Interop.Excel._Worksheet'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000208D8-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."}
I want to encapsulate the use of Excel Interop to make it easier to use somehow in a reuseable library.So far, I have written some tests that work good altogether, except that between each test, I force Excel to quite so that it does have handle on the test file no more in order to be able to delete.Once I quit the application instance between after each of my tests, Excel seems to be no longer responding, causing Windows to display "Excel has stopped working and is looking for a solution"
message. This message lasts a few seconds, meanwhile Excel is closing, causing the hang on the file to occur and my tests to throw an exception like "Cannot access file because it is being used by another process..."

This is what i do, i first export the data to excel then i import that excel file to another datagrid, this is just for testing cuz i will be getting excels from another computer same program, anyways, there are 2 columns that wheni import the excel file, it doesnt read it it shows in datagrid with no value,empty cell, i dont know why, because in excel the values are there, and all of them are strings sometimes it contains numbers, but theyre manage as string.
I added the images of excel file after i export the datagrid
and image of datagrid after i import that excel file NOTE THE EXCEL VALUES IN EXCEL< and empty in DATAGRID
I don't know how exactly it is called but I look for a function like in Excel when I write e.g. in the first cell a 1 and then pull the field down with my mouse and it automatically completes the following cells like that:
1
2
3
Is it possible to this in VB.Net and how except that I have to add every time one I have no idea.
I am trying to display an excel spreadsheet on a page using datagrid, but for some reason it is filtering out some of the cells, leaving a blank space instead. Also, the "$" sign won't show up in most of the columns.Could someone please take a look at my site and file, and give a suggestion as to why this would be happening? I've tried a bunch of troubleshooting on it, with no success.

I am working on exporting some data to a DataGrid (with no luck). So far I have:
[Code]...
When this runs, I get an error message that says: System.Data.OleDb.OleDbException: The Microsoft Jet database engine could not find the object 'Sheet'. Make sure the object exists and that you spell its name and the path name correctly. The excel file has only one sheet that is named "Sheet", and the location specified in the connection line is correct. Any ideas on why this may be happening?
This code works well however when data is exported to excel in one field some values are wrong. Instead for example populating 16-12-19 it populates 43815, 01-03-99 it populates 36220. Again, if the sort code is like 20-72-68 or 60-01-22 it is populated the same way, which is correct. If the value is a date lookalike then this problem appears, but if not then the exact value as displayed on the grid is shown in excel.
I inserted the code (highlighted in red) to set all the fields as text values. Right, it is exported and when excel spreadsheet is opened the field property is text, but the problem still exists. Why doesn't excel display it as it is displayed on the datagrid and database, instead of changing it even when set text.

I am working with Vb.net and this code below works fine. However, when I review the data exported to excel I have a problem with one particular field i.e., sort code. Sort code in the database is in the format 00-00-00. Therefore if it is 12-11-09 or 11-01-66, a look alike of a valid date it is disaplyed as 12/11/2009 and 11/01/1966 in excel after the export. Excel thinks its a date which is incorrect. I expect it to show 12-11-09 and 11-01-66.

View 2 RepliesI am having a problem using ACE. I am on Windows 7 64 bit and I am using Visual Studio 2010. I have inherited a program that needs to be converted from using JET to ACE as more and more users could not use it on their new computers. All this little application does is sort data according to selected fields and then insert blank lines whenever the data changes. It worked fine with Jet built in VS 2005.
Line 32 is where I am getting trouble. I get one of two error when I get to this point "IErrorInfo.GetDescription failed with E_FAIL(0x80004005) when targeting any CPU. I found suggestions from people on the web to target X86 in the advanced compile options but then I get 'Microsoft.ACE.OLEDB.12.0' provider is not registered. This I think is due to the system looking for the 32 bit version of ACE but I am using the 64 bit.
When reading through the code the line da.Fill(dt) is underlined with the comment "Variable 'da' is used before it has been assigned a value. A null reference exception could result at runtime." This confuses me as I declare it at the top and it gets used in the if the statement. The only reason for the underline I can see is that there is no option in case the incoming data is not from csv,xls or xlsx but since the open file dialog doesn't allow for anything else that shouldn't matter.

I have a problem loading big spreadsheets into a datagridview.
I had a similar code as above that i used and it works great if you have say 10000 cells to populate cell by cell.
How ever moving to 2 mil cells is a different cup of tea, the code took more than 7 minutes to load the data, and although the data was perfect in every way, its too time consuming, i cant get it to work faster so I used the datagrid instead.
The sheets needed to be imported is 350,000 cells plus. I used code that works realy great, does the import into the grid and transfers the data to a datagridview within 15 seconds with little resources which put a smile on my dail :) then i saw something and it dropped ...
see code:
[Code].....
My problem is that whenever there are values below the heading of the cell the datagrid displays (null)
No matter what i do even converting the values in excel to text it does not display the heading of that column.
When i paste other text into the cells below the heading (NOT NUMBERS) it shows the data and heading, Only if the "type" of content is the same does it display both the heading and the text that follows in rows below.

I am trying to read a date from a cell in excel into a datagrid and then compare the current date to the one in the datagrid, however vb.net converts the date (which should be of the form 03/09/2011 UK style) into a number so for instance 03/09/2011 becomes 40789
how do i keep it as a date so i can compare it to todays date?[code]...
