C# :: Multiple Tables Conversion From Excel XLS File To XML With OpenXML
Apr 25, 2014
I have downloaded this project from here -->> [URL] ....
This one works fine and it's a great commented code to understand even for beginners like myself, but it only works with one table per sheet. Once I add second table in sheet, it throws an error that something is wrong in one of the columns in my spreadsheet: It says: " Error occurs! The error message is: Cannot find column 4. "
Basically, I have this type of tables in my spreadsheet:
So I want that my program would export those two tables in a single .XML file (just read them both). And those two tables should be separated in two XML childs: the upper one should be Order-Header and the lower one - Line-Items, like this:
<ROOT>
<Order-Header>
.....
</Order-Header>
<Line-Items>
.....
</Line-Items>
</ROOT>
ConvertExcelToXML.cs:
[Code] ....
I copied all the code because I think it is the easier way to spot where to change it, to read those two tables in one spreadsheet and export them both in one XML file. How could I achieve this kind of functionality.

i'm trying to update multiple table values with same column using one query.
Here's what i've tried so far:
mySql.CommandText = "Update tbl_employees,tbl_emp_additional_info,tbl_allocated_deductions,tbl_benefits,
tbl_cashadvances,tbl_deduction_history,"+
"tbl_dtr,tbl_empabsences,tbl_empstatus,tbl_otherdeductions
,tbl_ots,tbl_payroll_history,tbl_rdcomments,tbl_reversed_deductions,tbl_reversed_deduction_paid "+
"set tbl_employees.emp_id=@newemp_id,tbl_emp_additional_info.emp_id=@newemp_id,tbl_allocated_deductions.
[code]...
I've also tried removing all the other "and" operators but still no luck.It doesn't throw in exception yet it doesn't update my tables column values.

I'm having a bit of trouble with something. What I'm trying to do is create a new Access table by combining other already existing Tables.
For instance, let's consider Table1 (with columns A, B and C), Table2 (with columns A, D and E) and Table3 (with columns A, F and G), where Table1.A = Table2.A = Table3.A.
From these, I want to create a new table TableResult, with columns A, B, C, D, E, F and G, with all the data contained in them. There's one catch: I want the code to get the names of the other columns, apart from column A.
I've thought about using Union, but I need to actually create a new table by combining the previous tables.

I have the following code which allows me to add the pdf files if I give the exact name and path of the file. But I have multiple pdf files in a folder which I want to add to each cell in the first column. I am having trouble thinking of the logic to have a for loop for a folder which contains the pdf files.
private void button1_Click(object sender, EventArgs e) {
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
xlApp = new Excel.ApplicationClass();
xlWorkBook = xlApp.Workbooks.Add(true);
[Code] ...
But this is very very rough draft. I have say 20 files in the folder pdf with different names(Title). How can I add all the 20 pdf files in the excel sheet?

I am currently having issues with the following code when trying to create a excel file using C#. This is the code that I have at the moment.
oXL = new Microsoft.Office.Interop.Excel.Application();
oXL.Visible = false;
oWK = (Microsoft.Office.Interop.Excel._Workbook)(oXL.Workbooks.Add(System.Reflection.Missing.Value));
oWK.SaveAs(path + "" + fileName);
oWS = (Microsoft.Office.Interop.Excel._Worksheet)oWK.Worksheets.get_Item(1);
oWS.Cells[1, 1] = "Student ID";
oWS.Cells[1, 2] = "Student Name";
oWK.Save();
The line that I am having issues with is
oWS = (Microsoft.Office.Interop.Excel._Worksheet)oWK.Worksheets.get_Item(1);
If I remove it, I am able to create and save teh workbook in the directory. However, I want to make some changes on a worksheet, and that is where the issue is. I have also tried using the line of code:
oWS = (Microsoft.Office.Interop.Excel._Worksheet)oWK.Worksheets[1];
This line had no luck either. The issue I am having is the error regarding InvalidOperationException: Dynamic operations can only be performed in homogenous AppDomain.

I am able to export a tabulated string to an Excel file, when I open the file in Excel it looks fine (3 rows, 3 columns). However, the formatting seems a bit dodgy as I can't then read the same file back using C#. If I open it in Excel and do a save as, then I can read it from C#.
fileWriter = new System.IO.StreamWriter(@"C:Sheet1.xls"); //
This overwrites file each time by default.
fileWriter.Write("COL_A COL_B COL_C
1 2 3
10 20 30");
fileWriter.Close();
To read the Excel file back i'm using the following code:
OleDbConnection cnn = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + (@"C:Sheet1.xls") + "; Extended Properties=Excel 12.0;");
OleDbCommand oconn = new OleDbCommand("select * from [Sheet1$]", cnn);
cnn.Open();
OleDbDataAdapter adp = new OleDbDataAdapter(oconn);
DataTable forceResultsTable = new DataTable();
adp.Fill(resultsDataTable);
The error I'm getting back is "OleDbException was unhandled" with "cnn.Open();" being highlighted in visual.

I wish to read an excel file which contains the table shown at the picture below.
I don't really know how to code the direct storage of the values in the appropriate array.
For example I wish to store the countries in an array of a string type.
could I have some piece of code which illustrates it (I mean the reading of an excel file and the direct storage of his value in an array).

I have been asked to create a program that accesses an inventory file done in excel, look for a alpha-numeric code, which will be inputed by the user, and return to the user informations related to the position of that code, and informations related to the header of the column in which the code resides.
An example of the function I need the program to perform would be:
User inputs: 1429-R1
And the program returns: Marco's 6A, 8/21/2014, 3/7/2014.
using the following example of file:
Marco's 6A
Assessment 8/21/14 3/7/14
1584-R1 1584-R1 1584-R1
1461-2R1 1461-2R1 1461-2R1
1429-R1 1429-R1 1429-R1

I have a program that converts document files to html , however there's a very strange issue with the program, it is only converting files that i open within the program using fstream i.e. ofstream out("test.doc"); now ill have to copy the contents from another document that i want to convert to this test file and it would convert but if i try converting a document that has not been implicitly created it would give me a garbage .html file.

// file extensions that the program can handle
// you can add more extenssions if needed

In my code I have lots of structures. I try to make tables of structures and then get access to elements of the structures to use them all along my code: here is an example to clarify things
typedef struct {
Fabric **closfabric;
}Network;
Net is part of another structure called Switch and Fabric itself is a composed structure. I have done the following
aSwitch->net.closfabric = (Fabric **)malloc(3* sizeof(Fabric *));
aSwitch->net.closfabric[0] = (Fabric *)malloc(m * sizeof(Fabric ));
aSwitch->net.closfabric[1] = (Fabric *)malloc(k * sizeof(Fabric ));
aSwitch->net.closfabric[2] = (Fabric *)malloc(m * sizeof(Fabric ));
The compilation returns a segmentation fault because aSwitch->net.closfabric is NULL (0) .
Surprisingly, in other codes the same analogy of using tables made of double pointers works perfectly with no problems and I have no problem of core dumped and NULL pointers.
Why am I getting this problem. It is the case whenever I try to use large dimension tables (tab *** struct for example)...
