I created a dataset that contains an empty dataTable that has several columns , and then I created a new report that is linked to this datatable using the report wizard. In my form there is a button when clicked should fill the datatable mentioned above ( I checked if it is being filled by displaying its content in a dataGridView and by firing a messagebox that is triggered when 'datatable.rows.count > 0' ).
The reason that the datatable is initially empty is that it depends on some conditions that may alter the query used to fill it.
But finally when I load the form that has the report viewer it only has the names of the columns of the datatable and no contents. What's wrong ?
I am writing a program that models the ups & downs of a particular stock. Everything is pretty much done, except that I need to create another event to notify that saves the following information to a file when the stock's threshold is reached: date & time, stock name, initial value & current value. I have something like this so far:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.IO;
[Code]...
I feel like i need something along the lines of
s.stockEvent += new Delegate( ???? ) in my myFile class so it know when the threshold is reached, to write the information of the current stock to the file.
Code: private: System::Void GOBUT_Click(System::Object^ sender, System::EventArgs^ e) { int x; x = sender->Location.X; }
Returns error saying Location is not a member of Object^.
I'm trying to create an array of button (user/runtime created buttons) and get different interpretations of the click event depending of wich button is clicked.
For example, if we create buttons[0] I wish to get the 0 or something relevant into the GOBUT_Click event.
I'm having problem using the click event in a web browser control. I have a control called CIEBrowser that implements a Web control. Here a message_map:
I have a dialog with a control using this CFulltextCtrl. I can create and show the html perfectly inside the form. But all links inside this control don't work (scenario 1). If I create a form who have a control of the type CIEBrowser, the EXACTLY same html code works perfectly (scenario 2).
In particular, I need that when I click in one link, execute a method called OnClick, who performs all that I need, just like in scenario 2.
This is my DISPATCH_MAP in the derived class (CFulltextCtrl):
I basically want to develop an application which print an existing file on reception of a network event (application will be running on a seven 64 bits PC).
I wonder which application type would be the most suitable (and the simplest) for that (console win32, win32 app, MFC app ...). As this application does not need user intervention (print on network event), I'm not sure that I need a MFC application or a win32 app.
I receive a telegram in XML format and I need to parse it and send my data in the same format back. My main problem is that I'm not allowed to use any open source software or other 3rd party software except VS2010. I have to write it in C++.
Now my question: is there any good tutorial for such a parser? I was hoping that I could write something which can be used similar to the GEtPrivateProfil-functions which are handy for ini-files.
Place the even lucky numbers in an array called evenList, the odd lucky numbers in an array called oddList, and the negative lucky numbers in an array called negList.
//So in main main i passed the array as parameter and the size;
void lucknumberlist(int favnum[], int size) { int even = 0, odd = 0, neg = 0; int evenArray[even]; int oddArray[odd]; int negArray[neg]; if(favnum[even] % 2 == 0) { evenArray[even] = favnum[even];
I want to read and write value on serail port to Microcontroller with MFC. The MFC have no serial port tool like in VB Professionnal edition. I try to find MFC connect serial port example but I not found. If you have good example for read and write on serial port with MFC
I can access a physical device to read a specific sector in a USB hard drive. But my question is how can I Write to a specific sector? Lets say I want to replace what is in a specific sector of a hard drive with a new data.
i need to write a function with an array parameter and an int parameter.
that array has to be filled with first 10 prime numbers that are exact or higher than the int parameter...and then i need an average value of those 10 prime numbers...
The problem is im not really sure how i should do the part to fill the array with prime numbers that are higher than that int??
Code:
int avgprimearray (int higharray[], int somenumber){ }
I'm new to c++ and boost library also. I need to test a function of my library. For example
// Functions.hpp int add(const int x, const int y); //Functions.cpp int add(const int x, const int y) { return (x + y); }
Now i need to test add function using boost. I need the result or output in below style. What all settings do i need to do in VS 2010 and how i should include boost test in the project.
==== Run unit tests ==== Running 2 test cases... ./mytest.cpp(13): error in "SimpleTestInMainTestingModule": check 1 == 2 failed Test suite "Master Test Suite" failed with: 1 assertion out of 2 passed 1 assertion out of 2 failed 1 test case out of 2 passed 1 test case out of 2 failed
I have to write a program where the user will input integer numbers. How many numbers they enter is unknown, therefor you should use a repetition structure for the input. When the user is done, they will enter -1 to exit.
Create a dynamic array if the size=2( the initial size must be 2) Repeat until user enters -1.
I have to do this without using vectors.
This is what i have, I cannot figure out what to put in main. I was thinking of a do-while?
Code: #include <iostream> using namespace std; void resize(int *[], int); int main() { int *listDyn; int size=2;
i need to change the text in multiple ComboBoxs. i could do it one by one, but i have about 11 i need to change. i feel like doing it one at a time is not efficient. i was wondering if i can put the comboboxs into an array so i can use a for loop to change them all with out writeing it out 11 times.
I am writing a application that receives Event messages from a network device the problem I have is that the device sends some message 5 times per tiggered event on two of the events I like to use the rest of the messages are fine I need to create code to filter out the other 4 last messages that get displayed in a textbox the 5 message are identical I have added a timestamp to the sting and noted they are always 1 second apart so the format would be somthing like this:
11:23:01 - x - y 11:23:02 - x - y 11:23:03 - x - y 11:23:04 - x - y 11:23:05 - x - y
What I would like to do something like this, always append the first message to the textbox but ignore or even change the 4 messages that follow 1 second apart from each other that contain - x - y if any other message appears it should still append the text box as well
so the result i would like for the 5 event message as above should end like this:
11:23:01 - x - y 11:23:02 - custome message / ingnore append to textbox 11:23:03 - custome message / ingnore append to textbox 11:23:04 - custome message / ingnore append to textbox 11:23:05 - custome message / ingnore append to textbox
I want to update a label from Form2. When I click on the button on Form 2, the textbox on Form2 should update the label on Form1 and take me to a certain website. What ever URL is typed into the textbox on Form2 is what website URL the label on Form1 will take me to. The label on Form1 can say something such as You can check out my website here!!! and when they click on the saying it takes me to their website.
I want to create events and then, functions which are subscribed to the event can access information about the event. For example, in Class 2 below, I want it to be able to access things such as touch.position, etc. of class 1.
Class 1:
public delegate void TouchEventHandler (EventArgs e); public event TouchEventHandler TouchBegan; public Vector2 touchPosition; void Update () { if (Input.touchCount > 0) {
I'm still at the very beginning of learning WPF and there are still countless things i don't fully understand. For instance, as I can see in my WPF project, there isn't an event that would fire when the Background property of some control is changed. Or am I just missing it? If i'm not blind after all, and it really doesn't exist, is there any way i could get notified when the Background color of some control is changed?
