The whole day I am trying to solve this simple issue, but without any success.
I found a lot of hints in internet, but seems, that none of them is valid for my problem.
My issue is quite simple: I want to change the caption of a menue item while runtime
But it seems, that all solutions I found are very specific.
My requirements are this:
- it is a MFC application (VS2010)
- It is a SDI application, not MDI
- I want to change the caption of a main menu item (like "File"), not an entry of a submenue.
Because of main entry item, there is no ID for the menu item. Therefore solutions with ON_UPDATE_COMMAND_UI will not work!
My problems are:
- either the code I tried, is generating an assertion or exception
- or the function call returns with false
- or the function seems to work well, but I do not see any result (the caption is still unchanged)
Maybe I am using the wrong functions, or the wrong place for calling the functions.
Has anybody an example, which would work within my application pre-conditions?
Many, many thanks!

Windows cleverly hides the function to modify a menu under the arcane name of ModifyMenu. I hate it when they do things like that. Really makes me wish for Linux/Unix, with nice clear names like shmdt and mvwaddchnstr. Anyway, getting off my soap box for the moment, you'd call it something like this:
GetParentFrame()->GetMenu()->ModifyMenuW(1, MF_BYPOSITION, 0, L"New Item");
GetParentFrame()->Invalidate();

Further to my earlier question
Migrating iOS Hybrid App from UIWebView to WKWebview
I have made good progress and only have a few loose ends to tidy up. The overall performance improvement over UIWebView is outstanding.
In UIWebView it was possible to set the focus on a text field programatically using
webView.keyboardDisplayRequiresUserAction = NO ;
However this is not available in WKWebView and ever since 2016 programmers have been developing an updating work arounds (swizzles) to overcome this.
I have tried implementing the latest of these I could find on Stack Overflow, which I found at https://stackoverflow.com/a/55344531/5948260
However as I am very inexperienced at coding in XCode please could someone tell me exactly how I add the above solution to my project. I have tried in vain to find examples of how exactly to do this i
on GitHub or elsewhere but to no avail.
So far I have tried copying the code provided in the above answer into a .m file and adding it to my project, but I got 20 or so errors, I then added an import statement for Foundation and most of these went away but XCode complained that it did not know what class WebViewInjection is. Also must there be a corresponding header file?. Must there be a corresponding interface statement? How does the method defined in the answer get invoked?
As I could not answer any of these, I also tried adding the method into my ViewController class. Whilst this was accepted with no errors, it had no effect on my app, ie. the keyboard did not come up automatically.
I would also want the webview to resize to appear above the keyboard and not to scroll to where the text field is as this seems a very messy solution to me.
All help very gratefully received.
I have now managed to get the keyboard displayed by adding
[self allowDisplayingKeyboardWithoutUserAction];
to viewDidLoad
I kept the allowDisplayingKeyboardWithoutUserAction method declaration inside my ViewController but changed the + infront of the method declaration to a - and this seems to have worked.
I still do not know how to resize the webview when the keyboard is displayed.
I need to execute a pascal code before that the Select Setup language Dialog is shown , unfortunately the InitializeSetup event is executed after.
function InitializeSetup(): Boolean; //This event occurs to late
begin
DoSomething();
Result := True;
end;
So it's possible execute a script code before of the Select Setup language Dialog is shown?
I had similar problem, and I thought about different workarounds: style all setup manually, or make inner localization, but they all looked so doomed from the beginning.
Select Setup language Dialog
I have forked issrc, built it locally, and looked at the main.pas of the Setup project. I see the idea behind doing as it is now : people may wanna use {Language} in InitializeSetup, so its called after the AskForLanguage method.
To just check the idea I made small changes to main.pas: call AskForLanguage after CodeRunner inited and InitializeSetup called. I got VCL'ed Select Setup Language dialog, but not all - NON Client Area wasnt VCL'ed:
I've tried to inherit the language form not from the TForm class but from the TSetupForm, or call it in the middle of setup or make other changes - with no result. If anybody know why it's not VCL'ed - tell me please!
Then I read the Custom Window Frame Using DWM article and just made the form border bsNone and got this:
So for now I'm fine with it. That form not styled before many pages of styled setup was so... annoying.
If we wanna do it a right way, I guess all that needs to be done - is moving CodeRunner init before AskForLanguage, and add a custom code function like StyleInit or so. Then all will be happy: {Language} will be available in InitializeSetup and Dialog will be VCL'ed.
No, the function InitializeSetup() is called as first.
All other functions are called later.
Of course you can modify Inno's sources and add custom functions but I think it is not your case.
Why do you need this? Maybe there is solution which can solve your situation, please tell us details.
Another possible solution is using Inno setup Ultra, it has several inprovements, and InitializeLanguageDialog function is one of them. just load style in it. (Also you can freely change language dialog itself that is so nice).
I have a picture that is getting printed in my MFC application. I'd like to add another page with another picture, so that 2 pages will be printed.
I know this is very poor description but the application is so big I can hardly know what's where.
First, locate your view-class. This will usually be something like CMyAppView - where MyApp is the project name. Inside this view class all printing stuff is handled.
You will most likely find overrides for OnPrint and OnFilePrint. In this methods you can adjust printer settings and page layout. And they will internally call OnDraw for your view. So, in OnPrint you add another page with EndPage and StartPage, and in OnDraw you really decide what you print.
If your printout should be different to your view on screen, you may have to store additional information on what to print when inside your class.
The EndPage and StartPage functions in the CDC class might be worth looking into.
Posibly you need to locate the print function and what data is printed.
I want to use the Watir to click a link that looks like a button attached the image.
I use the following method,but doesn't works:
#browser.div(:id,"NetworkAnalysisTabPanel").div(:index,1).div(:index,1).ul(:index,1).li(:index,1).link(:index,2).click
Note:
#browser.div(:id,"NetworkAnalysisTabPanel").div(:index,1).div(:index,1).ul(:index,1).li(:index,1).link(:index,2).flash
is working fine but click is not working in IE and FF
Link looks like this:
And HMTL like this:
Note: I am able to click on the element using selenium IDE with clickAt method
Try this (not tested):
browser.link(:class => "x-tab-strip-menu").click
If you can flash the link, but click does not do what you want, see this: How to find out which JavaScript events fired?
FYI what you have are links that are using standard background images controlled via CSS magic that keys on the class of the link to know what background to set. That's where the image comes from, and why you don't see it as part of the link in the HTML.
In that control, each tab is a list item element (li) in an unordered list (ul), and each list item has an ID, so that's the easiest way to tell it which tab you are trying to click inside.
Try identifying things starting with the LI that is the tab container, as within that container there is only one instance of each link of a given class. Of the 4 links, only one is without any kind of easy identifier, and if you need to click that one you'd need to use :index, but for the other 3 links using :class ought to work. This should result in code that is less brittle and subject to being broken if the order of tabs changes, or the page is refactored.
#browser.li(:id,"NetworkAnalysisTabPanel__ext-comp-1038").link(:class, "x-tab-strip-menu").click
If the number at the end of the ID is subject to change, you can try a regular expression to match the part you can predict and is unique from the others
#browser.li(:id,/NetworkAnalysisTabPanel__ext-comp-/).link(:class, "x-tab-strip-menu").click
If you can reliably identify the object and use .flash but .click does not seem to do anything, you may have to use .fire_event('onclick') instead or .click.
#browser.li(:id,/NetworkAnalysisTabPanel__ext-comp-/).link(:class, "x-tab-strip-menu").fire_event('onclick')
If that does not work, then you need to start experimenting with likely events that the control might be looking for (which will not necessarily show up in the HTML btw.. it may be in javascript or CSS etc)
UPDATE
This is where having an live example of the control that we can interact with is critical. doing some googling on the class names I was able to find one here and that let me play with it a little, and what I discovered is that it is looking for onmousedown. so, on that site, this works
browser.li(:id, 'TabPanel1__ctl07').link(:class, 'x-tab-strip-menu').fire_event('onmousedown')
Now since those ID's may not be the best identifier, a bit more digging (using .text on the li that holds the tab parts) found me some text, which in a menu like that ought to be unique.. SO, we can change this to make things a bit more robust and clearer as to what tab I'm clicking on (this will also be less subject to breaking if the tabs change around.
browser.li(:text, 'Menu 1').link(:class, 'x-tab-strip-menu').fire_event('onmousedown')
Lastly, since the click is causing client side code to execute, you may need a brief pause (a one or two second sleep) to wait for that portion of the page to re-render etc.
I have a core data document based cocoa app that is working well except for one slightly odd problem.
For some reason, if I make a change to any of my fields the menu/window don't seem to recognize it - ie. the red close button doesn't get the black 'dirty' indicator and the File/Save menu item isn't enabled. However, if I attempt to close the application (via command-Q), I do get the popup asking me if I want to save my changes.
It seems that the document's dirty flag is being set, but the window/menu items aren't reacting to it. I am curious as to where I might look to see why this might be the case. I suspect that it may have something to do with my window not knowing about my ManagedObjectContext...
The only slightly atypical behaviour is that my document's makeWindowControllers method has been overridden and I am adding my window controllers using a call to my document's [self addWindowController:xxx] method. My window controllers subclass from NSWindowController so I had to add my own instance variable to each window controller to hold the ManagedObjectContext, but I suspect that this isn't getting passed to the window/menu. Not sure what the normal pattern is here...
Anyway, any thoughts would be much appreciated. Thanks
From the description it sounds like your UI elements are not actually bound to the document itself. If so, then the UI elements are not observing the document and are not reacting to changes in the document. Check the bindings.
Thanks in part to TechZen, and also re-reading my own question (in particular, where I said "I suspect that it may have something to do with my window not knowing about my ManagedObjectContext") I started to look at the bindings for my WindowController subclass.
As it turned out, I hadn't bound the window outlet for the File's Owner to my actual NSWindow. As soon as I did that, the black dirty dot and the window's menus started behaving correctly.
