I transferred data from parent to child. Problem occurred while send data from child to parent dialog.
Find the attachment....

I'm using windows forms and I have a parent dialog box that consists of a text box and a drop-down that launches a child dialog box. The child takes user input and then prints dialog to the text box in the parent. However, the output does not appear in the text box until I close the child.
Now my question is, how do I get the text to appear without closing the child? I hit a button to send the info to the text box, but it still doesn't appear until the child closes. I also need to set up a button to suspend the child so that the user can click/copy/etc the parent.
Is there any standard USB protocol which i can follow to send data to my embedded board(and vice versa). I have no clue on USB programming using c,is there any example code i could follow,
View 4 Replies View RelatedI've created a modeless dialog from my main dialog as follows:
Code:
m_pContainerDlg = new CDlgContainer(NULL, this);
m_pContainerDlg->Create(CDlgContainer::IDD, GetDesktopWindow());
m_pContainerDlg ->ShowWindow(SW_SHOW);
This container dialog creates a child dialog which I show inside the container
Code:
BOOL CDlgContainer::OnInitDialog(){
// Create the child dialog and show it
m_pChildDlg = new CChildDlg(this);
m_pChildDlg->Create(IDD_DIRECTORY_DIALOG, this);
return FALSE;
}
From my child dialog I then create a modal dialog when a user clicks on a button
Code:
CChildDlg:: CChildDlg (CWnd* pParent /*=NULL*/) :
m_pParent((CDlgContainer*)pParent), {
} void CChildDlg::OnBnClickedBtn() {
CMyDlg MyDlg;
INT_PTR iResult = MyDlg.DoModal(pParent);
}
My problem is that the CMyDlg is modal but to the main dialog and not to the container or the child dialog.
I was looking for a C++ library for use as stated in the title. I was considering using Voce; however, for the project, I wanted to be able to use a custom voice. For example, in most TTS programs you can pick voices. I wanted to record a custom one. However, I don't really know how these libraries work internally, and since the text to speech is referred to as synthesis, it seems they are created through algorithms rather than recordings. Is there any library which I could use a custom recorded voice with?

I have a main dialog which has (DDX?) controls for the user. eg a slider, and a combo box.
Previously, an image adjusted by these controls was in the same dialog.
I need to put this image in a New, separate dialog but it still must be controlled by the slider and combo box on the main dialog.
My question is how can I pass the control's variables between the dialogs? I have, say,
Code:
//MainDlg.cpp
DDX_Control(pDX, IDC_ComboBrightness, m_Brightness
I was told that I could do something like:
Code:
//ImageDlg.h
public:
ImageDlg(CWnd* pParent = NULL, CComboBox m_Brightness); // standard constructor
But I get errors including: Missing default parameter for parameter 2
I also need to pass the image array, is that perhaps the same method?

#include <string>
#include <vector>
#include <map>
const int ENUM_NOT_FOUND = -1; const std::string NEW = " ";

[code]....
Ouput with GCC 4.8.1:
Monday
Tuesday
Wednesday
Thursday
Friday
Saturday
Sunday
Name a day: Friday
day = Friday
But the problem is that whenever I define a new enum, I have to define the << and >> overloads for the new enum again. Isn't there a way to template that as well, so that the << and >> overload needs to be defined just once? My atttempt:
template<typename Enum>
std::ostream& operator << (std::ostream& os, Enum en) {
return os << EnumConversions<Enum>::toString (en);
[Code] .....
fails to compile. I guess the problem is Enum is not known at compile time, even though it should be deducible during run time? Error mentions ambiguous overload for operator>>.

View 11 Replies View RelatedThe problem is that I want to write a C++ program that converts an ordinary text file into binary and then reads that binary file and converts it to text file so that this text file equals to first text file. I have wrote this code for it.
int main() {
string name1 = "first", name2 = "sec", name3 = "third";
int j = 0, k = 0;
ifstream ifs(name1.c_str()); // Here I want to read from the ordinary text file (name1).
[Code] .....
Now what the ofs.write(as_bytes(j), sizeof(int)); or ifs.read(as_bytes(k), sizeof(int)); exactly mean?
In practice, the file name1 contains digit 5 and its size is 1 byte. The name2 contains some character/sign like [] and its size is 4 bytes and name3 contains digit 0 and its size is 1 byte, why? I before have created the name1 file in ordinary text file mode.

i open child dialog from a dialog( which is launched from a toolbar of a window) after editing i close the child dialog, after closing child dialog shadow is retained on window but not on the parent dialog. Later when i close the parent dialog the child dialog shadow disappears. (issue exist only when i edit in child dialog)

I haven't seen it anywhere and I've been looking. Is it possible to display data, say in a CEdit field in a dialog as soon as the dialog starts? Either before or after DoModal is fine.. These are essentially the same.
Using Visual Studio 2013 - trial version. It's nice. Coming from VC6. Many things are familiar (so far), at least in the C++ part.
I am trying to display some data in text format on a dialog and I am using a CString to do it. Below is how I coded it.
Code:
CString outputStr;
CString auxStr;
// Add header
outputStr.Format("");
auxStr.Format("%-7s%-20s%-7s%-20s%s
[Code] .....
But the output rows are not aligned as shown in the attached picture. There a two problems.
1. Data rows don't align with the header row.
2. When the first element of a row changes to two digits, the other elements are shifted.
According to MSDN [URL] ...., CString::Format() works the same way as printf(). I wrote a small program using printf() to do the same thing, and the output in the console are perfectly aligned.
What have I missed when doing the display in GUI?
I am currently having an issue with a piece of code that I am writing in which I need to use a vector of a child class as a parameter in a function in the parent class. Below is an example of my code:
#include "child.h"
#include <vector>
class parent {
parent();
function(std::vector<child> children);
// rest of class here
}
When I do this my program doesn't compile. However if I try to forward declare, as shown in the following example, it once again refuses to compile:
#include <vector>
class child;
class parent{
parent();
function(std::vector<child> children);
// rest of class here
}
This time, it refuses to compile because it needs to know the full size of the class child in order to create the vector. How to being able to access the child is essential for my program, so what should I do?

How can I create MS Word 'print layout' like interface. The attached picture says it all. Basically I want a shaded area around my document just like word so it gives a feel of the 'page'.
I was hoping I can override some function somewhere and along that lines tried playing around with below but that didn't work.
Code:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs) {
if( !CFrameWndEx::PreCreateWindow(cs) )
return FALSE;
// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs
cs.cx = 250; // just playing around with size
cs.cy = 250;
return TRUE;
}
How can I do that?

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).

Code:
LPCTSTR AFXAPI AfxRegisterWndClass(UINT nClassStyle,
