I am writing an MFC app in Visual Studio 2012 that will open a JPG file as binary and read all the contents to a CString.
I am able to read it to a std::Vector, but that doesn't work much as i need to pass all the binary content as a MFC CString to another function.
More Update:
Let me explain the problem a little more deeper.
I am trying to call a JavaScript (JS) function in a HTML page and then want to pass the binary date. The C++ function that calls the JS is given below.
bool CallJavaScript(const CString strFunc,CComVariant* pVarResult);
The 1st argument is the JS Function Name and 2nd is the one to pass the Binary Data. 1st argument works fine as i am able to call the JS fucntion called "LoadImage" without any problem. Problem is with 2nd argument that's supposed to take the Binary data of the JPG file.
If i try to pass a std::Vector or std::string then it will give me an error.
But it's happy if i pass CString. But then with CString there's a problem with NULL characters.
Actually my plan is to pass the binary of a JPG to a JS function and let it display the JPG in the HTML page.
Can i typecast a Vector or std::string to a CComVariant*?
I am new to using classes, and am running into an issue already. I have created the class, and am in the process of adding data to the classes. I have added one piece of data, and now just want to see if I can get it to show in another function, but I am not sure why it is not showing. What about getting the data to show. Then, I will be able to work on adding the rest of the info.

I m making calendar in server control page by taking composite control.I am also adding textbox in each cell of calendar. Now i want to access the value of each textbox of selected month and respected date in default.aspx page on button click event. Here the button is not a custom control but defined in default.aspx page..
Can't access textbox text and date or controls of server page in website(default.aspx) page.

View 4 Replies View RelatedIn 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.

Currently I have to manually look up values on several different tables in different locations. I have 8 or 10 tables with 100 to 500 parts.
I would like to write a program so if I enter a value it will return the corresponding correct answers from the tables.
If I entered 2.5 for a value it would return the following three items from the tables since they all meet the requirement.
Table 2
Part min max
235 2.4 2.9
Table 6
Part min max
589 2.3 2.5
Table 7
Part min max
12 2.3 2.7
What would the best method be for setting up and accessing tables like this? Is C++ good at representing something like this or should I be looking at a different language?
i have stuck in a join and i cant figure out where the problem is, i have those tables
public class Themes

[PrimaryKey, AutoIncrement]
public int Id { get; set; }
[Code].....
Basically I have a few tables in my Database.
So I have one table that is like so:
Item_ID, Name, Parent ID.
1 , jeff , 5
and another table like this:
Parent_ID, parent_Name
5,jackson
What I would like to happen, when I run my code is that I'll get the following
Item_ID, Name, parent_Name
1 , jeff , jackson
DataSet DS = new DataSet();
if (this.OpenConnection() == true) {
mySqlDataAdapter = new MySqlDataAdapter("select Item_ID, NAME, Parent_ID from table1, table2", connection);
mySqlDataAdapter.Fill(DS);
dataGridView1.DataSource = DS.Tables[0];
//close connection
this.CloseConnection();
}
So this spit out parent ID = 5.
I've not worked with Dataset before and I was just wondering what is the best approach? Can this be done via a SQL command or will I have to replace the value(5) with the string(jackson) using a large IF loop to search and replace.
I'm trying ultimately to do a radix sort. I'm going with the implementation using two tables. One will initially hold the unsorted values then hold the partially sorted values thereafter. The other will be an array of linked lists which will be where the radix sort is done. Here is my code thus far:
Main
#include <iostream>
#include <fstream>
#include "radix.h"
#include "radix.cpp"
using namespace std ;
int main ( int argc , char * argv [ ] ) {
ifstream input ( argv [ 1 ] ) ;
[Code] ....
It appears to be crashing during void insert_into_sorted ( int to_insert , int place ) ; and I'm not sure why.
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 2 tables with primary and foreign key
Customer Details
EID - Primary Key

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>

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.

Now I'm getting the value of id i.e "DisplayImages.aspx?id=3" from DailyDarshan.aspx and want to display the images of each respective link according id.. when I click on "DisplayImages.aspx?id=4" link so it has to show the if(id == 4) images...but The problem is int id its not taking value itself.on DisplayImages.aspx.cs page I must have to define the id. for e.g. I wrote int id =3; on DisplayImages.aspx.cs file so it shows the images of id = 3 on each and every link.. Tell me what should I do to take value from another page or else how int id takes value by itself...
I've run across this issue before, but for the like of me, I can't figure out what keeps causing it. The problem compiles and runs as expected; however in the salaried object (Employee #1 in main.cpp) the console displays the number of vacation days as -858993460 instead of the value entered.
The parent Employee class is abstract with calculatePay() and displayEmployee() being pure virtualls and with a Benefits, Salaried, and Hourly class derived from it.
The Salaried displayEmployee() and the portion of the Main.cpp that contains the salaried object follows. What causing this?
Salaried displayEmployee()
Code:
void Salaried::displayEmployee()
{
cout << endl;
cout << "Employee Information" << endl;
cout << "----------------------------------" << endl;
cout << "Employee Name: " << setw(7) << FirstName << " " << LastName << endl;
cout << "Gender: " << setw(12) << Gender << endl;
