Visual C++ :: How To Define Name Range With Excel Automation
Mar 4, 2015
Using Excel Automation in Visual Studio 2010 C++, how do I define a name? As a user of Excel, you can enter a name that then can be used in formulas to refer to a range of cells. The range changes as the user inserts columns or rows. My program has worked with various versions of Excel dating back to the early 2000's.
I have a bunch of classes derived from COleDispatchDriver: CXLApplication, CXLRange, CXLWorkbook, CXLWorkbooks, and CXLWorksheet that have many functions, but I have no documentation... How to define a named range using functions of these classes (probably CXLRange)?

We have a C++ 5.0 app that does something like this:
Creates the excel dispatch, exports the data, etc...
...
then calls these functions:
xlsApp.SetDisplayAlerts(TRUE);
xlsApp.SetVisible(TRUE);
xlsApp.SetUserControl(TRUE);
This has always worked to display the excel spreadsheet in the foreground, most recently on Windows Server 2003.
Now, testing on Windows Server 2008, the excel spreadsheet is created, but in the background. How to force it to the foreground?

I want to define a range of exit codes in my application. These codes will be used as a return value of ExitInstance function. I want to know the exit codes availables (values not used for example by windows to inform about an other error). When I force to crash my application, I get some different error codes: 8148, 10176.
What is the no available range exit codes?
Is this the ranges code unavailable?

I want to create an application that automatize different applications in the sense that my application will be able to press automatically different buttons on another application.
For example: my application will start, let's say, Microsoft Office, will press some buttons in MSOffice, and will close MSOffice.

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'm trying to minimize an Excel window using c++. but it doesn't work.
Code:
//Save the PID
HWND hWnd = FindWindowA(NULL, (LPCSTR)pXlApp);
GetWindowThreadProcessId(hWnd, &proccesID);
// Make it visible
[Code].....
I checked the HWND is not null, but is not visible....
Code: bool visible=IsWindowVisible(hWnd);
and visible=false, but the window is Visible (I see the Excel file)

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 just got a job programming a windows application. One of the requirements is reading and writing values from an excel spreadsheet. Looking online, it appears that C++ isn't the best (one of the worst?) languages for reading and writing values from excel files. Now the language I'm most familiar with is C++ and I've been looking at C#, and it appears to be much easier to read excel files.

So there is suppose to be a constant that shows the total number of values to be shown in this range. The user enters two values, lets say userMin is -2 and userMax is 2, it's suppose to add 0.2 to -2 and so on until it reaches 2. It starts doing that up until it reaches -1.0, then it goes to -0.9, -0.7.... etc, It also goes beyond 2.
Code:
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
cout << fixed << setprecision(1);
float userMin;
float userMax;
[Code] .....

I'm having problems with progress bar when using a big number in set range. For numbers below 50000 it works very well but for big numbers like 100.000 it doesn't work, it makes 2-3 rounds of animation
Code:
int number= 50000; // 50k works well but if i put 100k it won't work (it will animate 2-3 rounds instead of complete one)
progressbar1.SetRange(0, number);
progressbar1.SetStep(1);
for (int i = 0; i < number; ++i) {
listcontrol1.InsertItem(i, _T("whatever"));
progressbar1.StepIt();
}
What's wrong with the code ?

In my app the user can select the pages to print by typing in a start and an end page. I think this is the standard dialog.
How can I give the user the possibility to select e.g. page "1,2,6-9" like in Word?

Write a function named generateLotteryNumbers. The function is passed an int array of size 5. The function should generate 5 different lottery numbers in the range 1 to 50 inclusive and place the numbers in the array. The declaration is as follows:
void generateLotteryNumbers (int lotteryNumbers []);
Note that no data is passed in to the function. The array is used to return the function results. Thus the parameter is an OUT parameter. Do not display the result. Return the result.
Do not seed the random number generator inside the function. If you seed the random number generator inside the function and the function is called many times in the same second, your function will return the same results each time it is called.
I know how to generate the numbers in the specified range but I do not know how to test for duplicates. Here is the code I have so far:
Code:
//This program will test the "generateLotteryNumbers" function
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
void generateLotteryNumbers (int lotteryNumbers[]);
[Code] ....
When I try to compile this, my compiler tells me that lines 41 and 46 require an array or pointer type.

I have a ULONGLONG variable uDate which express the number of dates starting from 0001-01-01, up to 9999-12-31. Now I want to convert it into a string like this
"yyyy-mm-dd"
However, the COleDateTime can only express the date from 100 to 9999, smaller than what I need. So are there any third-party classes or libraries that can express this. Or make the conversion from uDate to CString?

I am new to C# and just want to understand if an entire Test Automation Framework can be built using only C#. I would not want any dependency on available commercial tools in the market for executing the Test Action steps. Though a few points that i see will need to be taken care of at the onset.
1. creating and maintaining Object repository in some form of file extension
2. preparing a GUI for capturing user Test Action Steps
3. retrieving the respective test objects from Object Repository and firing the respective Action commands on those objects
4. handling test data within the Automation Framework Solution folder.
I have been exploring a series of blogs and found that point # 2 and 4 are achievable. However points 1 & 3 above looks a big challenge.
