Im working on a small code and am trying to limit the size of the mysql databse string its pulling.
It can only be 119 characters, or less if its more i would like to do nothing, but if its meets the requirements it runs the script.
Code:
int32 message_id;
string_t message ="Is requesting some one to respond.";<_______________TEMP SHOULD BE THE POSTERS MESSAGE
string_t username = "Guest";<_______________TEMP SHOULD BE THE POSTERS NAME
// char will not be logged in so get the id manually
[Code] ....
So here is where I'm heaving the problem
if(message is less then 119 characters run script )<<___________THIS IS THE CODE LINE IM TRYING TO LEARN
{
char buf[110];
sprintf(buf,"[Web Chat] %s %s",username.c_str(), message.c_str());
I am trying to make a double array, but I keep getting an error Segmentation fault (core dumped) when I make more than 105 elements in the array. I need to make 114 elements.
I am building my array with myarray[999] and increasing the number doesn't seem to do anything.
how do I tell the if statement to output this error message 'exceeded the maximum amount of characters' that has its characters stored in an array using c-style string?
[INPUT] The cat caught the mouse! [OUTPUT] Exceeded the maximum amount of characters (max 10) #include<iostream> #include<string>
In my attempt to capture multiple files using CFileDialog I discovered that there is a limit on the number of characters in the file name buffer. [URL]
I have used this code to get the file names and it works fine up to the point where the buffer is full. NB: m_vcsPathnames and m_vcsFilenames are std::vector<CString> types.
Code: // get a list of the files to process wchar_t szFilters[]= _T("All Files (*.*)|*.*||"); // Create an Open dialog; the default file name extension "*.*" CFileDialog fileDlg(TRUE, _T(""), _T("*.*"), OFN_FILEMUSTEXIST| OFN_HIDEREADONLY | OFN_ALLOWMULTISELECT, szFilters, this); m_vcsPathnames.resize(0);
[code]....
Is there any possible work around for this limitation, other than completely writing my own CFileDialogExx class ?
comparing with screen size the height is bigger but lenght is smaller. I don't understand.
I can understand that different printers process the fonts in different way and then to have different lenghts. That's not the problem. The problem is I need to simulate in screen the same behaviour i will have on printer because these texts are being aligned in the document, and I don't want to see that the text si aligned different in text than in paper.
What can I do to render the text on screen with the same size I will have on the printer? Print preview is doing it. Should I change the font parameters? is something related with pixels per inch?
I have following code to create histogram, but it gave wrong output. In the program input_vector read 100 double numbers. I want to create a histogram with bin size=5. Output is [0;0;0;0;0].
I am using Visual C++ to write an app. I write CMyObject class and may allocate a lot of instances of CMyObject object, so I want to reduce the size of CMyObject class.
What I can figure out to do is:
1. I can use the following code to get the accurate size used by a single instance of CMyObject object:
CMyObject Object;
//Get the size of memory allocated for CMyObject object int nSize = sizeof(Object);
is that correct?
2.To reduce the size of CMyObject, I have several ideas:
(1)Change member function to static member function if it is possible, since each member function will take some spaces in the instance of CMyObject.
(2)Change virtual member function to member function if it is possible, since virtual member function may take more spaces.
(3)Eliminate unnecessary member variables to reduce spaces.
(4)Finally, if (1), (2) and (3) does not work well, then change CMyObject from class to a struct that only contains some member variables, thus will eliminate the spaces allocated for constructor and destructor of a class.
In a MDI-app with some toolbars and statusbar I created also a controlbar which can be docked to the left side. My problem now: how do I get the exact height of the controlbar?
In CalcDynamicLayout I set the height for the docked state to the height of the mainframe. This value is too big, but it will work basically.
But how can I get the exact height of the controlbar?
I need use GetTextExtent and I don't understant why GetTextExtent always return the same value if I change some values of the selected font. This is my example:
An ImageList_Create() function (see here) takes 2 parameters: cx and cy which are the width and height of each image.
Everything is good if I know in advance what size my images will have. But what if I don't?
Let's say I select 32x32 and my images are sized as 16x16. What will happen with the image list? Or my images are 48x48 and the image list should grow to accomodate the extra space. Since on Windows image list is just one big bitmap, will the height of the image list shrink/grow to 16/48 or not? Is there a way to test such behavior?
The problem I'm having is to check whether the actual images will be truncated when they are bigger that the image list initial size or not or whether I will see some extra space if the images are smaller.
The closest way I see is this function, but I am not sure its the right one to apply to the image list itself and not to the image inside the list.
How to test this properly and reliably on Windows XP+?
I have created an exam environment for our schools, it comprises of 3 files; a .kix file that says if they are in the examination group run a .vbs file. The .vbs file kills the explorer.exe task so they don't have any taskbar or desktop shortcuts and then opens a .hta file.
The .hta file is a user interface that has icons for apps like Win Word that executes the application when you click on it. There is also a log off button.
Looking for some code that stops the students from being able to close, minimise and resize the window. Looking for code that can lock this down so they literally can't do anything except click the icons inside the window.
I have to rearrange my controls in a controlbar based on the new size resulting from dock/undocking of the bars or resizing of the mainframe.
Is there a message I can use? How to determine the new height when docked?
I tried to use its OnSize-function. The problem with it is to get the new height. When the function is called, the height I get from GetWindowRect is the old height.
Is there any way to set a "lock" on certain couts from system ("cls"). You can this with const to "lock" a variable to a certain value so I am wondering if that is true for couts from system ("cls"). This would make my program much simpler to write.
I have to find the sum of primes below limit. My program works fine when I try to find primes less than 10. However, when I run it for the sum of primes less than 100, I get 166337 when I am supposed to get 1060. My program works on modular arithmetic, where any prime greater than 3 can be expressed as 1 or 5 mod 6.
Here is my code:
#include <iostream> using namespace std; int main(){ unsigned long long prime, sum; int limit = 100;
I have created a new array and have wrote a code which will decrease || increase the value of the array element. I been trying to figure out how to set the value limit. For Example:
int[] stock = new int[] { 10, 10, 10, 10 };
How to set a limit on the elements that they will never go below to the negative integers and over 10?
