there is a way to iterate through the controls on a webpage. For instance, I tried EnumChildWindows using the parent window of the browser, but I haven't had any luck - it returns nothing. s where I can start researching how to find the child controls?
I'm using Visual Studio 2010, programming in C++.
This is my very first attempt at running a wpf browser app... I've create the project and i can see controls when i add them to the entry page, here's the default for the page
<Page x:Class="SandBoxWeb.Page1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
[Code].....
and i can see a nice bright green square with an orange outline. But when i debug, a new tab opens up in my browser and i can't see a single thing,it's just a white screen.
I'm trying to create a simple webbrowser at my app.
code sample:
....
ATL::CAxWindow m_wndContainer;
ATL::CComPtr<IWebBrowser2> m_spWebBrowser;
HWND hWnd = m_wndContainer.Create(NULL,
CRect(0,0,200,100),
(LPCTSTR)0,
WS_CAPTION|WS_THICKFRAME|WS_OVERLAPPED|WS_MINIMIZEBOX|WS_MAXIMIZEBOX);
CoCreateInstance(CLSID_WebBrowser,NULL,CLSCTX_INPROC,IID_IWebBrowser2,(void**) &m_spWebBrowser);
...
everything is work fine except the fact the it seems that it create an IE version 7.0 and my machine have IE 8 installed.
it not suppose to create the IE according to my installed version?how do i suppose to do it?
My earlier attempt to get an answer didn't work, so i want to make my question more straight forward.
Is it possible to create a C++ DLL with Web Browser like CDHtmlDialog embedded in it?
I create an IWebBrowser2* object and attached it to new window.
I create also a simple html page containing JScript alert(JSON) command.
when i load the page from IE the page works fine.but when i load the page from my object i get JSON undefined.
do i need to set my object with some setting?
I am making a dialog app using CDHtmlDialog and all the controls are done using HTML.
Now i want to call/display this dialog inside a web browser like IE.
How can i do that?
If i could generelaize this question -
Is it possible to display a dialog app that is derived from CDialog inside IE?
If possible, how to do that?
I have a COM Object created using ATL (without MFC Support)
The Object has 1 method that opens a Dialog (that does all the rest) and when finish - returns 2 values back (1 is enough)
Currently I call it from another EXE:
hr = CoCreateInstance(
CLSID_MyControl,
NULL,
CLSCTX_INPROC_SERVER,
IID_IMyControl,
(void**) &pMyControl
);
and then:
hr = pMyControl->MyMethod (ATL::CComBSTR(InputString1), ATL::CComBSTR(InputString2), &IntReturned, &IntReturned);
Is it possible to call it as is from a browser ?
How can I Instantiate the object and invoke my method (with params) from the browser ?
will it open the dialog ?
I have an C++ application which uses Microsoft Web browser ActiveX control to launch any URL within the application. The browser is embedded in C++ form and It's working fine with all the feature Microsoft has exposed through Interface(IID_IWebBrowser2).But while any url that is using session cookie has been launched, even after closing the browser the session cookies are not getting deleted. For example if user login info is stored as session cookies,the url is using the cookies and getting launched without asking for user log in info.
But if I close the browser, and again relaunch , the cookies should be deleted and the url will not find the cookies to be used for log in . That is not happening here. Although this is session cookies , it's not getting deleted and being used by embedded browser. However, if the url is launched in IE, it is behaving as expected.
So, Do I need to delete the cookies explicitly? If Yes, How to do that?
I'm turning mad with a little problem with Visual Studio 2008 and MFC. I'm working on a project actually and I'm trying to create an SDI Application. Right, now I want to add a dockable DialogBar. Well, the first time I added it with the resource view, I can create the bar without problems. But... I want to add some controls like a couple of ListBox, buttons and so on. The program doesn't allows me to create member variables for these controls. The option appears in grey.
Searching a little, I found that it's mandatory to create a new class derived from CDialogBar and "enhance" it with the Message handler and so on. I've been reading some tutorials and it didn't work for me.
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?
I have a dialog app with two separate static controls. Both controls have been subclassed from CStatic derived class to implement drag and drop and double clicking. The class works just fine, but I cannot figure out which of the controls is being double clicked or dragged and dropped onto because I only have the code below operating. I need some method in the derived class to determine which control is being manipulated.
Code:
// header file
#pragma once
#ifndef __AFXWIN_H__
[Code]....
I have a SDI application that uses a CFormView class to create a window and this window has 2 buttons and 2 edit boxes.
I can resize this window, like minimize and maximize, but the controls all stay at the same place.
I know that it's possible to move the controls based on window size.
But what i want to do is, as the window is expanded the controls and it's text content to grow proportionally and same when the window is shrinked.
Is that possible to do? i.e., increase/decrease size of controls and texts per window size.
I have migrated my MFC application from Visual Studio 6 to VS2010. But the UI controls still looks the same as of old theme. How can i add the manifest file now to get the UI controls to be displayed as of the current OS theme. i.e. Win7 look if the application is run on windows 7.
View 1 Replies View RelatedI 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 need make a CBitmap or a streamdata from a System.Windows.Controls::Image(rendered out put)in a SDI mfc application (supporting clr). Here is my codes:
Code:
using namespace System;
using namespace System::IO;
using namespace System::Collections::Generic;
using namespace System::Windows;
using namespace System::Windows::Controls;
[Code] .....
By this codes i can read datastream from bitmapSource but in this way somthing goes wrong in most of GIF animations. After debug i found out i need 3 more things too decode a gif animation - (x,y) position and size of each frame and disposal method for each one - finally i just found a way to draw tru images on a form window by this codes:
Code:
System::Windows::Window^ mainWindow;
mainWindow = gcnew System::Windows::Window();
mainWindow->Title = "GIF Imaging Sample";
//ScrollViewer^ mySV = gcnew ScrollViewer();
array<System::Byte>^ pixels = gcnew array<System::Byte>(bitmapSource->PixelHeight * Stride);
[Code] ...
When i change
Code: bitmapSource = decoder->Frames[0];
to
Code: bitmapSource = decoder->Frames[01];
frame[1] has drawn perfectly on window(i think some how Image class takes care about - (x,y) position and size of each frame and disposal method for each one ),so im wonder if how can i make a CBitmap or a data stream from System.Windows.Controls::Image class to use in mfc app.
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 a better function than OnSize() ?
I've created a dialog based MFC app which input from user to create that many dynamic controls(Used checkbox to be created dynamically).
After user input that many checkboxes controls are created but if try to click again then not able to delete previous controls and again new no. of controls.
Code snippet to add controls on user input.
RECT rctA;
rctA.top = 51;
rctA.bottom = 80;
CString temp;
m_Edit.GetWindowText(temp);
int noOfControls = _tstoi(temp);

I used onctlcolor() method to set the background color for the controls & Dialog. I run my application, working good but after 15 mins the below error occured,
Application Error:

what is the reason for that? How can i prevent my project from this problem.
I can't get tooltips to show up for the windows I want in my CFormView derived class. I have copied the code from the MSDN entry on EnableToolTips(). But only two windows respond with a tooltip:
CONTROL "Tree1",IDC_TESTPLANS,"SysTreeView32",TVS_HASBUTTONS | TVS_HASLINES | TVS_EDITLABELS | TVS_SHOWSELALWAYS | WS_BORDER | WS_HSCROLL | WS_TABSTOP,1,36,85,91
CONTROL "Tab1",IDC_TABCMD,"SysTabControl32",0x0,101,0,239,181
Other windows do not respond. For these windows my function designed to catch the TTN_NEEDTEXTW and TTN_NEEDTEXTA messages is not called. Windows such as
LISTBOX IDC_TESTPLANNAMES,0,119,48,40,LBS_SORT | LBS_NOINTEGRALHEIGHT | WS_VSCROLL | WS_TABSTOP
PUSHBUTTON "",IDC_BTN_COPY,105,177,24,24,BS_ICON
Why wouldn't the messages be sent for those windows? I'm using the code
ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTW, 0, 0xFFFF, &CCntlrView::OnTtnNeedText)
ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTA, 0, 0xFFFF, &CCntlrView::OnTtnNeedText)
(CCntrlView is the name of my class derived from CFormView.) And as I pointed out, I'm using the code straight from the example given in MSDN for CWnd::EnableToolTips(), with the only difference being that all my controls are created in the rc file as shown above.
Suppose I want to represent an apartment building in terms of floors and rooms with a single data object. Each floor has the same number of rooms at any given time. During the course of the program, I will need to change the number of floors occasionally and will need to change the number of rooms on each floor occasionally. (Don't worry about the building permits needed to do this.) Now, I also want to be able to iterate over either each floor (think "row") or each room (think "column"). For example, I might want to program the equivalent of "Johnson, go fix all the front doors on the 8th floor" or the equivalent of "Johnson, go fix all the front doors to room B on each floor". (Yeah, I know, for the latter I could iterate over each floor and then access room B but that doesn't feel as "clean" as being able to iterate over a separate room/column.)

Suppose I have a struct with 20 members. I want to assign each of those structs with values. Instead of accesing by explicit convention, i.e.:
Code: struct.member1 = 1;
struct.member2 = 2;
...
...
...
struct.member20 = 6;
Is there any way to encapsulate it in a for loop and use an iterator variable to indicate the member? i.e.:
Code: for (int i = 0; i < 20; i++)
struct.i = i;
The above is pseudocode but Im sure you get what Im trying to do?
If I have a Vector of pointers, how can I iterate through that vector, to access the name function of each object in the vector? There seems to be a problem with my implementation, the output returns only random symbols.
Implementation of the name() function in Drug.cpp:
//name() is a function returning the name in the parent class
string Drug::name() {
string out = "Drug: ";
out += mName + " [ ";
//The problem is with this loop
for (int k = 0; k < mComponents.size(); k++)
[Code] .....
what do I do if the while loop repeat iterating and do not stop running even if it did meet the conditions required?
