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:
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 have a requirement where I have to import a lot of text files into excel. Up till now I can import the text files using visual studio C# but after importing the format is not exactly the way I want (mostly the delimiters). So I have to manually use the text import wizard and make the changes. I was just wondering if there is any way to program all of it. Delimiting the spaces, specifying the column widths, eliminating a few rows and columns.
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.
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'm kinda new to c#, i wanna create a program which will take few data from GUI and export it into an excel file. Another thing is how to modify the data displacement in that particular excel file?
I am very very new to C++. A bit of background. I have been writing in excel vba for large number crunching, and the code is now taking quite a while to run. A friend of mine suggested i start writing in C++, so i read up on it. And downloaded Code:Blocks.
My VBA Code is:
Sub arrayss() Dim NameArray As Variant Dim datarray As Byte Dim DirectionArray As Variant Dim WinArr As Variant
[Code] .....
Ultimately i would like to recode this to C++, but my first and probably silly question is how do i get the data from Excel to use in C++. I was thinking either to put the data in 3 csv files and convert into three Arrays in C++. Or maybe create a library of the data in C++. Ultimately it is speed i am looking for, so before i start recoding i wanted to start with the best way.
The data is like this in excel: (don't know how to create a table)
So the headers would be in one array, the 15's, 30's etc would be in another array and the 1's and 0's and Empty ( i need it to record an empty cell) would be in another 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.
I have to compare data in excel and csv based on the file name and update the status of file from CSV into excel file by creating a new column status on weekly basis.
Is it possible to create an app that can be saved on my desktop that can be used with an excel file that is saved on my desktop? I have opened VS 2010 and I have created a form design that has a button for every sheet name in my excel file. All of the sheet names are hidden with the exception of one. When a button is pressed on the c# form, I would like for that sheet to be shown in excel. Then once the updates have been made to that sheet in excel, I want a button to be at the top of the excel worksheet that will hide that worksheet again and return to the form c# form...can that be done?
I am using Excel 2013, Visual Studio 2015. I began learning about Excel XLL. I wrote simple function which tests whether the argument is missing. Here's code:
how to extract certain cells for an excel file that is continuously updating. I had a look at [URL] since they provide a .h library that is useful for this situation, but could not find any code.
I want to export the windows form in which text box,label and gridview ,gridview export to excel is working fine,but i need to export the whole form as such to excel.Is there any option to select Panel : This is my code:
I'm attempting to write a method that opens a file from Excel, finds a value within the spreadsheet and returns the value from another column along that row.
So I know I want to pass in the filename and the item I'm initially searching for, plus also a column identifier and that way I can locate so something like this:
public static int GetParameter(string filename, string parameter, string channel)
I've attached a snip of the spreadsheet so you can see what I'm lokoing at. I want to open the spreadsheet, find the parameter I've specified, move along the column to find the channel I've specified and finally read and return the value.
The bit that's troubling me is I have no idea how to work with excel in c#. I've done a few searches and I believe I need to add thiese references
using DocumentFormat.OpenXml.Spreadsheet; using DocumentFormat.OpenXml.Office2010.Excel; using DocumentFormat.OpenXml.Office.Excel; using Excel = Microsoft.Office.Interop.Excel; using Excel;
I have added those usings and also made reference to them in my project. I was also looking at this as well but it just confuses me in how I add my parameters and modify the code to suit:
using System; using System.Windows.Forms; using Excel = Microsoft.Office.Interop.Excel; namespace WindowsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent();
Is not the first time I upload this program i know, but the problem now is that i try to export files, because i need to create an excel graph. But when I try to run it, I don't have any result, no file and no result of the program.
Code:
#include<stdio.h>#include <time.h> #include <cstdlib> #include <math.h> int randfun(double arrX[], double arrY[], int size); int cenfun(double arrX[], double arrY[], int size); int rotatefun(double arrX[], double arrY[], int size, double center_x, double center_y, const double angle);
I have to develop an application that uses Qt, Excel and live-time file checking. My client gave me this:
I have a problem at work. I need you to develop this: I want one application with GUI (it said windows), that generates an report for each sheet (employee name) in the file, with the columns. I don't want to make the computer slower, so check the file and get the name of the employee that is altered and only change his report
How to start it. All Excel libraries I use stop working on my computer and this "File Checking" is other trouble, because if for each second I compare the size of the "old" file with "new" file, the memory will explode.
