Visual C++ :: Exporting Struct From DLL
Nov 8, 2013I'm trying to build the gtkmm library using MSVC. One of its source files declares a struct called BuiltinStockID together with some objects of that type - e.g.
Code:
// In the header file:-
namespace Gtk {
struct BuiltinStockID {
const char* id;
[Code] ....
GTKMM_API is obviously _declspec(dllimport) (or export) as appropriate. It seems a bit unusual to use extern in addition GTKMM_API but the code won't compile if I try to exclude it. The actual instantiations are in one of the library's source files- e.g.
Code:
// In a source file
const Gtk::BuiltinStockID APPLY = { GTK_STOCK_APPLY };
const Gtk::BuiltinStockID CANCEL = { GTK_STOCK_CANCEL };
const Gtk::BuiltinStockID OK = { GTK_STOCK_OK };
GTK_STOCK_APPLY etc are simple strings such as "gtk-apply". They mostly refer to image files for the library to load (in this case, for dialog button images) although that's probably not relevant to the problem.
If I run dumpbin /EXPORTS on the built DLL it does seem to have some exported symbols with the names Gtk::Stock::APPLY, Gtk::Stock::CANCEL, Gtk::Stock::OK etc. However, if I write this in one of my own source files:-
Code:
Gtk::BuiltinStockID MyStockID;
MyStockID = Gtk::Stock::CANCEL; // <--- debugger reports <Bad Ptr>
You can see that the Gtk::Stock::CANCEL object is invalid (my debugger reports it as a bad pointer). Likewise, if I try to pass Gtk::Stock::CANCEL as a parameter to a function.
C :: Importing / Exporting Library Functions
Feb 22, 2015I already have this but I sense I'm missing something so I'd like to be pointed to a proper article/document on this sorta thing.
Code:

#define PP_ATTR( TYPE ) __attribute__( TYPE )
#ifndef _PRAGMA
#define _PRAGMA( COMMAND ) _Pragma( #COMMAND )

Visual C++ :: Exporting Class Or Member Function?
Oct 2, 2012Usually we use the following statements to export a class or member functions,
Code:
#ifdef DLLMICRO
#define DLLIO __declspec(dllexport)
#else
#define DLLIO __declspec(dllimport)
#endif
I understand that the files using the exported class or function need to call this class or function with dllimport and the file containing the exported class or function needs to call this class or function with dllexport. But I tried to use __declspec(dllexport) only instead of the statements above. It still works. Is there anything I am missing?Why'd we have to switch between dllexport and dllimport?

Jan 2, 2013Is 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?
View 2 Replies View RelatedC++ :: Excel XLL Returns Different Results?
Feb 1, 2015I 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:
#define DllExport __declspec(dllexport)
static LPWSTR rgFuncs[1][7] = { { L"GetSum", L"BU", L"GetSum" } };
DllExport double WINAPI GetSum(LPXLOPER12 arg)
{
if (arg->xltype == xltypeMissing) return -1;
return arg->xltype;
}
This code works as expected: if I miss argument, it gives me -1, and the type otherwise. But when I change code to this:
DllExport double WINAPI GetSum(LPXLOPER12 arg)
{
return (arg->xltype == xltypeMissing) ? -1 : arg->xltype;
}
then, when I miss argument, it gives me 4294967295. Why?

C# :: Opening / Finding And Reading A Value From Excel
Jul 3, 2014I'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() {

C Sharp :: How To Create Excel File In C#
Dec 28, 2013I 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 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.

Jan 15, 2015I am displaying data from an Excel Spreadsheet through an ASP.net web form using C#. I would like to run an SQL query on the data, but am having trouble figuring out how to use a string in my query.
Here is the code I am running in my .aspx.cs file. I am also using a .aspx to display the data in a GridView.
public partial class ExcelAdapter : System.Web.UI.Page {
protected void Page_Load(object sender, EventArgs e) {

Ideally, I would like to add a WHERE clause to my string (string sSQL = "SELECT * FROM [Sheet1$A1:D14]"/> in order to query the current month and display the row of said month from the Excel Spreadsheet.
I have attempted to use a DataAdapter to insert the string into the query, but could not figure out how to conform my code to work with it.
