Get Text From EditTextBox Widget

[#1]

Hi Expects,

I'm new to this community. In facebook most of them suggested to post my queries in adobe community to get better solution. Here's my query,

I coded to get the EditTextBox widget text value during button click. 

Plugin gets build successfully. In Indesign when i type some text in EditTextBox and by clicking button it shows starting alert message and then InDesign gets crashed. I can't find what's the problem in my code....

if (widgetid == kGetTextButtonWidgetID)
{
CAlert::InformationAlert("1");
InterfacePtr<IPanelControlData> panelControlData(this, UseDefaultIID());
IControlView* EditTextBoxView = panelControlData->FindWidget(kSampleTextEditBoxWidgetID);
InterfacePtr<ITextControlData> EditBoxTextData(EditTextBoxView, UseDefaultIID());
PMString temp;
temp = EditBoxTextData->GetString();
PMString returnText = temp;
CAlert::InformationAlert(returnText);
}

Thanks In Advance...

Hi Parvathi,

Do you get any crash report, are you using debug build of InDesign, that should help you in debugging. The code you shared looks fine at first look but the issue could be anywhere its hard to guess. You just pasted the code of if block it may be possible there is something wrong above it and it causes a crash on method exit.

Set a breakpoint and see whether EditTextBoxView = … actually found anything.

Otherwise, the EditBoxTextData is also just a fancy NULL pointer.

Further down, better check that using " if( EditBoxTextData ) …" before you access its EditBoxTextData->GetString().

But then, as Manan suggests, in the debug build there should be an assert on the operator -> .

Maybe the problem is anywhere else.

[#6]

So doesn't the debug build give any asserts before crashing?

Hi Manan, Dirk

It shows that InDesign CC 2017 has stop working....

As per Dirk suggested i checked the EditBoxTextData again it shows the meassage InDesign CC 2017 has stop working.....

I've modified my code and found the issue....

Actually the issue occurs in 

InterfacePtr<IControlView> EditTextBoxView(panel->FindWidget(kSampleTextEditBoxWidgetID), UseDefaultIID()); in this line....

InStead of  kSampleTextEditBoxWidgetID i used kGetTextButtonWidgetID to check the data appears or not.....

By giving kGetTextButtonWidgetID InDesign works correctly.

In returnText it shows the kGetTextButtonWidgetID button text in alert....

How to fix my error in above mentioned line???????????

Code i've modified is

if (widgetid == kGetTextButtonWidgetID)
{
CAlert::InformationAlert("1");
InterfacePtr<IWidgetParent> myParent(this, UseDefaultIID());
InterfacePtr<IPanelControlData> panel((IPanelControlData*)myParent->QueryParentFor(IID_IPANELCONTROLDATA));
InterfacePtr<IControlView> EditTextBoxView(panel->FindWidget(kSampleTextEditBoxWidgetID), UseDefaultIID());
InterfacePtr<ITextControlData> EditBoxTextData(EditTextBoxView, UseDefaultIID());
PMString temp;
temp = EditBoxTextData->GetString();
PMString returnText = temp;
CAlert::InformationAlert(returnText);
}
