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.
I have a problem with implementing Shadow Mapping into a project I am working on. I am very much new to shaders and I have been given a Shadow Mapping shader to implement and understand. I have mostly got my head round the concept and the code but I can't figure out why its not working.
As I understand it the main steps to follow are;
1) Render the scene from the POV of the light - this is done in ShadowMap::SetUpDepthRender where the view and projection matrices are passed to the shader.
2) Render all objects in the scene - this creates a shadowmap (depth map) via the shader.
3) Reset the view and projection matrices to that of the camera - done in ShadowMap::SetUpSceneRender.
4) Render the scene objects once more appling the depth map to them via the second pass of the shader.
The problem Im having is that I have a stripe of light running diagonally across the screen. It passes through the point of the spotlight that I am mapping for. I believe this is the shadowmap being applied to the scene however I could be wrong?
Below is the code in the ShadowMap class used for setting the fx file.
LPDIRECT3DSURFACE9 oldDepthSurface = NULL;
LPDIRECT3DSURFACE9 oldRenderTarget = NULL;
ShadowMap::ShadowMap(void) {
//Create our Light
Vector3D lightPosition(20.0f, 2.9f, 10.0f);
Vector3D lightDirection;

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?

how to split a child window in an MFC MDI program.
Splitting Child Window in MFC MDI Program
[URL]
For my purposes, this achievement is practically useless because I cannot find a way to pass text from one CRichEditView window to another.
Given two CRichEditView windows, CInputViewView and COutputView as child windows in an MFC MDI app, my goal is to capture text in the former and print that text in the later using a button click.
Using what appeared to me to be a logical way to proceed, I tried variations of the following code:
Code:
void CMainFrame::DoSomething() {
//MessageBox(_T("Like What ?"), _T("Do Something"));
//CInputViewView * pin = (CInputViewView*) GetActiveView();
CInputViewView * pin = (CInputViewView*)m_wndSplitter.GetPane(0,0);
pin->GetWindowTextW(m_csDisplay);
[Code] ....
None of this works and even the attempt to access the pane results in an app crash in winsplit.cpp.
Code:
#ifdef _DEBUG
void CSplitterWnd::AssertValid() const {
CWnd::AssertValid();
>ASSERT(m_nMaxRows >= 1);

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?
I am using a CEdit control as a child in a CListCtrl for purpose of making each column editable. The application is a dialog based app. My problem is... I have overwritten OnOK and OnCancel in the main dialog so the edit control never receives notifications for Escape or Enter whether in OnChar or PreTranslateMessage and I would like to delete the CEdit control after updating the CListCtrl on Enter. What can I do? I have rewritten this code many many times over the past 4 days and nothing is working.
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.
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.

View 14 Replies View RelatedFor 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 ?
I was wondering how can we know how many items exist in a dialogbox? If there any way that i can get the items ID in a dialogbox by having just the dialogbox's object or handler? Or any way that we can get a dialogbox content by coding.

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.
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?
