Visual C++ :: Modal Dialog Unexpectedly Becomes Non-modal

Mar 10, 2015

I have a modal dialog. When I click on a button in the dialog to perform an operation, a non-modal dialog is displayed showing a progress message.

The operation is not successful. It calls WaitForSingleObject and times out. This seems to have an adverse effect on the modal dialog, which strangely becomes non-modal.

My code:

CIMFlashBox FB(nInstrumentUID, sMessage);
eStatus = SetRegister(nInstUID, IM_CONFIGURE_REG, eForceSet, sMessage, bForceSet, FALSE);
FB.DestroyWindow();

The first line displays the modeless dialog. The second line performs the operation, which calls WaitForSingleObject. And the last line destroys the non-modal dialog.

C++ :: Multithreaded Program Using Modal Dialog Box

Apr 9, 2014

I am writing a piece of code using gtkmm and ran into this problem. This is how i am getting the problem.

class someobj {
Gtk::Window* pWindow;
// Thread 2
void run() {
while(1)

[Code] ....

I think it is not dependent on gtkmm because thread 2 is blocked where as the parent thread is running which is causing the problem.

Visual C++ :: How To Set The Parent Dialog

Apr 17, 2013

I'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.

Visual C++ :: Catching A Dialog Box?

Dec 9, 2013

What I want is simple: I want to catch a dialog box!

The dialog box pops very frequently in a website. We have to put a username and password and press OK. I checked with spy++. It doesn't have any child windows. So catching the dialog box with windows API is ruled out. It must be a HTML dialog. I have to get DOM COM interfaces of the dialog.

Another option may be to make an add-on to get the interface to IWebBrowser2 and get the events fired. The title of the dialog box is "Authentication Required". If the events will be fired for that dialog box, I can check the title using IHTMLDocument2::get_Title.But will the events be fired for HTML dialog box? How to catch that desturbing dialog box.

Visual C++ :: FTP With Progress Dialog

Nov 13, 2012

For a project I'm working on, I need to be able to download a file from an FTP server and store it to a predetermined location with a predetermined name. No user interaction should be needed. Because the file is rather large, and I need the main program to remain responsive, this is going to need a progress dialog.

I could write all this myself and use the MFC wininet wrappers (CInternetSession et al) to do the downloading, but... Explorer already has this, and IE has such a dialog also. It doesn't seem unreasonable to assume those dialogs are available via some API.

Is a "FTP download with dialog" available as a windows API, or do I really need to write all this myself ?

C/C++ :: Vector Contents Unexpectedly Different Within The Same Function

Jun 14, 2014

I am trying to create a tennis tournament simulator. There are 128 players in the tournament, and 32 seeds. I have a vector filled with 'Player' objects named 'Players'. Each 'Player' object has three member variables, Strength, Ranking, and ATPPoints. When the vector 'Players' is first declared, the default constructor for each 'Player' object is used, which initialises each of the 'Player' objects to zero. I then generate a Strength value in the range of 0-10 for each of these 'Player' objects, and sort them descendingly according to their strength.

I now want to create the draw for a tournament. I declare a vector 'Draw' with 128 'slots'. Each slot initially contains a blank 'Player' object, with its member variables set to 0. I first place the top 32 players throughout the draw such that they do not meet until later rounds as they would be in real life. For the remaining players, I position them in the draw by generating a random number between 0 and 127. Some of the slots 0-127 are occupied by seeded Players. These seeded Players have non zero Strength and Rank values, so to avoid overwriting these slots, I check the Strength value of the 'Player' object in the slot in question. A return value of 0 would indicate an empty slot.

At the beginning of the function, I output the Strength and Rank values of the 'Player' objects already in the draw. This outputs correctly.

for (Player& p : Draw)
{// outputs the draw in it's current state, with the already placed seeds as expected.
cout << p.GetRanking() << " " << p.GetStrength() << endl;
}

I need to pass a variable to a dialog box.

Code:

Aug 22, 2014

I have a ListCtrl on my dailog. It has a report view. In my case I have selected first row with left click of mouse and entire row is displayed in blue color as selection (as per expected) and when I right click the second row of the listctrl it displays the menu which I have added to it and the selection remains with the first row.(as expected). I have already overridden the ListCtrl class.

I want that on the right click of second row the selection should remain with the first row but this second row also should be displayed with dotted line border.

Visual C++ :: Slider Not Working Properly In A Dialog MFC?

Jul 3, 2013

I have a slider control on a dialog box. I am playing a video file and slider moves according to the video elapsed. Suppose I have set the slider range to 100. Now till some point say 90, the slider moves to the point wherever I click the mouse. but at the last point in between some range say 90 - 100 (to the end of the slider), if I click the mouse button anywhere, slider jumps to the end.

I am using a TimeLine control where user can add more than 1 video (1, 2, 4, 8, 10 , 50 etc......), If I use only one video, slider moves as per the video progression.....Issue arises when I add more than 1 video and click on the start button, slider starts moving....Now when I drag the slider to any position or I click the mouse button anywhere on the slider control, slider thumb moves to that position and immediately jumps back to some other position. This is the Issue, I am facing.

share some sample code where slider is moving with the video showing the progress of the video.

I want to implement a functionality similar to VLC player. Wherever user clicks the mouse, slider moves to that point.

Visual C++ :: Intercept Messages Sent To Controls On A Dialog

Apr 8, 2013

If it is possible, I'd like to know how to intercept messages sent to controls on a dialog. I'm working on a large application with a large number of dialogs, each with a number of controls on the dialog. I need to be able to intercept messages sent to these controls so that I can determine if the controls really need to take action on these messages. I could subclass each control and override the specific event handlers but due to the volume of controls in the application this could take a very long time, will introduce risk if controls are missed, and will increase maintenance costs. What I want to do is create a class which is derived from CDialog and each of the dialogs in the application would then be derived from this new dialog class. The new dialog class would intercept messages sent to any control on the dialog and if the dialog decides that the control should do something then the dialog will pass the message on to the control.

example:
CExistingDialog is derived from CNewDialog is derived from CDialog

CExistingDialog has a number of controls. When the code in CExistingDialog calls CWnd::EnableWindow on one of these controls I want CNewDialog to intercept the message, determine what should be done with the message, and then pass it on to the control.

I'm not very familiar with the messaging framework. I've tried overriding a few of the methods of CNewDialog but none of them ever receive the message to enable the window. I assume this is because the message is sent directly to the child window (the control).

Is there any way to intercept these messages? I don't know much about hooks either but is this a possible option?

Visual C++ :: Show Some Rich Text In A Dialog Box?

Nov 26, 2012

I have been told to show some text document when our application starts up, it is an EULA. They gave me a word file and I saved this file in a .rtf format. I then wish to show this in a dialog box and found this on code guru: [URL]

Which seems to be a sub-class that will do all the formatting for me. So I use that class and then load in the .rtf file, using their setRTF method I just get an empty text box.

I just want to be able to show this formatted, somewhat pretty text from this document in my application as close as I can to the original document. Is there an easy way to do that? I could turn it into plain text, but I think that my boss would not be happy about that.

The problem was that I needed the text box to be marked multi-line.

Visual C++ :: Unable To Display Dialog In UI Thread

Mar 11, 2015

I am having a strange problem trying to display a dialog from a UI thread. The dialog simply fails to display. I have a function DisplayFlashBox(), which creates the UI thread:

CUIThread* CIMUIHelper:: DisplayFlashBox(const CString &sMessage, const int nInstrumentUID) {
CUIThread *pThread = new CUIThread();
pThread->SetString(sMessage);
pThread->SetInstrumentUID(nInstrumentUID);
pThread->CreateThread();

[Code] .....

The dialog doesn't display. When I tried debugging, I found the OnInitDialog() method of CIMFlashBox class doesn't actually return. Very strange. I tried calling the DoModal() method instead of Create, but doesn't display the dialog either.

Visual C++ :: Using CDHtmlDialog In MFC Dialog Based Project

Aug 30, 2013

I am trying to use CDHtmlDialog in a MFC dialog based project.

What i want to achieve is pretty sample. Have one image, one button and one text box in the HTML page.

And then dynamically change this based on a timer. i.e., there're multiple images in the folder and it will change every seconds. Once the button is clicked, the timer stops and no more image changes. Same time when image changes the text in the text box also should change.

I know this is pretty simple, but for some reason i am not able to make the image even display in the dialog.

I am using Visual Studio 2012 in Windows 7 machine.
