  • Is it possible to have yui editor change paragraph style without selecting text?

    - by user126861
    Is it possible to change the behavior of the yui text editor so that when you make markup changes (via the toolbar bar buttons), for example changing from a paragraph to say a heading or to a list, and you dont have any text selected it assumes you mean the current block that the cursor is in So to change a paragraph to a heading rather than selecting the whole line you just place the cursor somewhere in the paragraph and select heading from the styles drop down.

  • breakpoint inside QComboBox subclass not working

    - by yan bellavance
    I have subclassed QComboBox to customize it for special needs. The subclass is used to promote QComboBoxes in a ui file from QtDesigner. Everything works except that when I put a break point in a slot, the program does not stop at the breakpoint. I do however know that it is being called from the result it generates. I checked other slots in my program and they work fine with breakpoints. Doing a clean and rebuild all did not fix it. What could be causing this and is there anything I can do about it? The slot in question is the only one in the subclass and is called "do_indexChanged()". You can find the slot on line 37 of the class header below and the signal-slot connection on line 10 of the class source file. CLASS HEADER: #ifndef WVQCOMBOBOX_H #define WVQCOMBOBOX_H #include <QWidget> #include <QObject> #include <QComboBox> #include <QVariant> class wvQComboBox : public QComboBox { Q_OBJECT //Q_PROPERTY(bool writeEnable READ writeEnable WRITE setWriteEnable) public: explicit wvQComboBox(QWidget *parent = 0); bool writeEnable() { return this->property("writeEnable").toBool(); } void setWriteEnable(const bool & writeEnable){ this->setProperty("writeEnable",writeEnable); } bool newValReady() { return this->property("newValReady").toBool(); } void setNewValReady(const bool & newValReady){ this->setProperty("newValReady",newValReady); } QString getNewVal(); int getNewValIndex(); int oldVal; //comboBox Index before user edit began private slots: void do_indexChanged(){ this->setWriteEnable(true); if(oldVal!=currentIndex()){ this->setNewValReady(true); oldVal=currentIndex(); } } protected: void focusInEvent ( QFocusEvent * event ); //void focusOutEvent ( QFocusEvent * event );//dont need because of currentIndexChanged(int) }; #endif // WVQCOMBOBOX_H #include "wvqcombobox.h" wvQComboBox::wvQComboBox(QWidget *parent) : QComboBox(parent) { this->setWriteEnable(true); this->setNewValReady(false); oldVal=this->currentIndex(); connect(this,SIGNAL(currentIndexChanged(int)),this,SLOT(do_indexChanged())); } void wvQComboBox::focusInEvent ( QFocusEvent * event ) { this->setWriteEnable(false); oldVal=this->currentIndex(); } QString wvQComboBox::getNewVal(){ setNewValReady(false); return this->currentText(); } int wvQComboBox::getNewValIndex(){ setNewValReady(false); return this->currentIndex(); }

  • Large number of UPDATE queries slowing down page

    - by Bryan Lewis
    I am reading and validating large fixed-width text files (range from 10-50K lines) that are submitted via our ASP.net website (coded in VB.Net). I do an initial scan of the file to check for basic issues (line length, etc). Then I import each row into a MS SQL table. Each DB rows basically consists of a record_ID (Primary, auto-incrementing) and about 50 varchar fields. After the insert is done, I run a validation function on the file that checks each field in each row based on a bunch of criteria (trimmed length, isnumeric, range checks, etc). If it finds an error in any field, it inserts a record into the Errors table, which has an error_ID, the record_ID and an error message. In addition, if the field fails in a particular way, I have to do a "reset" on that field. A reset might consist of blanking the entire field, or simply replacing the value with another value (e.g. replacing the string with a new one that has all illegals chars taken out). I have a 5,000 line test file. The upload, initial check, and import takes about 5-6 seconds. The detailed error check and insert into the Errors table takes about 5-8 seconds (this file has about 1200 errors in it). However, the "resets" part takes about 40-45 seconds for 750 fields that need to be reset. When I comment out the resets function (returning immediately without actually calling the UPDATE stored proc), the process is very fast. With the resets turned on, the pages take 50 seconds to return. My UPDATE stored proc is using some recommended code from http://sommarskog.se/dynamic_sql.html, whereby it uses CASE instead of dynamic SQL: UPDATE dbo.Records SET dbo.Records.file_ID = CASE @field_name WHEN 'file_ID' THEN @field_value ELSE file_ID END, . . (all 50 varchar field CASE statements here) . WHERE dbo.Records.record_ID = @record_ID Is there any way I can help my performance here. Can I somehow group all of these UPDATE calls into a single transaction? Should I be reworking the UPDATE query somehow? Or is it just sheer quantity of 750+ UPDATEs and things are just slow (it's a quad proc server with 8GB ram). Any suggestions appreciated.
