• How can I determine new & previous cell value on SheetChange event in Excel?

  - by Falco Foxburr

  I have some special cells in my Excel workbooks which are managed by my Excel Add-in. I want to prevent users from changing content of those cells, but I also want to know, what value users wanted to enter to those cells. On the SheetChange event I can check what users entered to my special cells, but how do I determine the PREVIOUS value in those cells and REVERT user changes? It is not a solution for me. If I lock cell in Excel, it becomes read-only - user can not even try to enter anything to this cell - Excel popups warning dialog in this case. My problem is that I want to catch what user entered to my cell, do something with this value, and then revert cell content to original value.

• Help with implementing a function to change size of dynamic array

  - by iRobot

  I'm trying to write a function that will change the size of a dynamic array to a new size. In my header file, I have: Image **images; //pointer to a dynamic array of image pointers int maximum; //size I want to do this by allocating a new array and copying the values over without changing their indices. If there are non-null pointers outside the range newmax, then we cant do this. So heres what I have: There are no compilation or runtime errors. However, I find that the new array isnt getting sized right. When I run the following test case: I should get an index out of bounds error, but instead the system lets it slide. Can anyone see the mistake? I've looked for hours but cant find anything.

• Converting between square and rectangular pixel co-ordinates

  - by FlyboyUtah

  I'm new at using transforms and this type of math, and would appreciate some direction solving my coding problem. I'm writing in XCode for the iphone, and am working with CGraphics. Problem: In Xcode, I want to draw curves, lines and so on it's screen of of square pixels. Then convert those points, as close as possible, into non-square pixel sysem. For example if the original coordinate system is 500 x 500 pixels that are displayed on square screen of 10 by 10 inchs I draw a round circle with the circle formula. It looks round, and all is well. Now, I draw the same circle on a second 10 x 10 inch screen that is 850 pixels by 500 pixels. Without changing the coordinates, the same circle formual displays something that looks like an egg. How can I draw the circle on the second screen in a different coordinate system? And in addition, I need to access the set of points x,y system individually. s

• Customizing compare in bsearch()

  - by Richard Smith

  I have an array of addresses that point to integers ( these integers are sorted in ascending order). They have duplicate values. Ex: 1, 2, 2, 3, 3, 3, 3, 4, 4...... I am trying to get hold of all the values that are greater than a certain value(key). Currently trying to implement it using binary search algo - void *bsearch( const void *key, const void *base, size_t num, size_t width, int ( __cdecl *compare ) ( const void *, const void *) ); I am not able to achieve this completely, but for some of them. Would there be any other way to get hold of all the values of the array, with out changing the algorithm I am using?

• A pointer member variable having different values

  - by Rohan Prabhu

  Ok, to begin with, this is my code: HyperSprite::HyperSprite() { _view = 0; } void HyperSprite::publish(QGraphicsView* view) { _view = view; } void HyperSprite::getKFrame() { if(_view != 0) { qDebug()<<(void*)_view; } } Now, if I call HyperSprite::getKFrame() from within main(), I get the output: 0xbf8ffb84 I have a TCP server, which requires this QGraphicsView* variable. So whenever a new connection is made, HyperSprite::getKFrame() is called. However, whenever I make a connection to my server, this is the output: 0x1e425ff I honestly don't understand this. Shouldn't the value of a member remain same throughout? Why is the pointer value changing? As is obvious, whenever I try to use the _view pointer to access any of its members, a Segmentation Fault occurs. I tried using QSharedPointer, but it also results in the same problem. The data of the QSharedPointer automatically changes. Why is this happening?

• Can I set JFrame's normal size while it is maximized?

  - by icza

  I'd like to set the normal size of a visible JFrame while it is in Frame.MAXIMIZED_BOTH state (by normal size i mean the size of frame when it is in Frame.NORMAL state) . The reason I want to do this is so that when the user un-maximizes the frame, it will have the proper size I want it to be. But if I do so, the window will switch to normal state. If I set the size first, then switch to MAXIMIZED_BOTH state, then I will see a disturbing blink or resize (which I don't want to). I've also tried setting the size first, then changing state to MAXIMIZED_BOTH, and then making it visible, but the state change is deferred if the window is not visible (and will only be executed once it is made visible, also resulting in a visual resize). So what can I do if I want my frame to have a predefined normal size, but I want it to appear maximized?

• where to place browser event (resize/scroll) detection call

  - by karl

  I'm trying to alert a message when the browser is resized or scrolled. I'm detecting the 2 events in the body <body onResize="doDisp();" onScroll="doDisp();" > where doDisp is this inside the <script> tag <script type="text/javascript"> function doDisp(){ alert("browser changing state"); } </script> but isn't it bad practice to have javascript in the body tag? Is there a cross-browser way to keep all the javascript inside the <script> tags?

• Google Analytics - Goal Funnel Steps

  - by Daniel

  Is there a way to test the url you're entering in a step, to see if Google Analytics will recognize it? What I'd like to do is provide some web page or some web service with a URL, and get a pass or fail. It passes if Google Analytics recognizes a page hit to the url. Let me give some context. We've been having issues with our goal funnel steps in Google Analytics. The instructions on adding steps say not to use the domain. e.g. DO NOT use : http://www.mysite.com/step1.html INSTEAD use: /step1.html Our custom CRM uses friendly urls and as a result GA is having a hard time picking up on them. So we've experimented with changing around url we've placed in the step, however we've got to wait a day to see if the new url we've provided is going to work! Hence why we're looking for something quicker.

• Visual Website Optimizer and Code Igniter

  - by absentx

  We are trying to integrate visual website optimizer into a site of ours that uses Code Igniter. The problem is when we go into the VWO control panel to look at stats and previews nothing seems to be working. In the previews panel, all of them come up as code igniter error pages that say "The URI you submitted has disallowed characters." I have researched some solutions to this and have tried changing the regex in system/config to allow more characters, all characters etc and I am still having the problem. Any known issues or problems trying to integrate VWO and Code Igniter? This definitely seems to be a url issue but I can't nail it down.

• selecting all text within a div on a single left click with javascript

  - by tstyle

  I have a simple non-clickable link within a div that looks like this: It's meant to be a sharable link that the user can copy paste into other things. For usability purposes, I want a single left click anywhere within the div to select the entire link: I don't know much about, javascript/web programming, so I've tried the following: <div id="share_link" onClick="select_all('share_link')"><%= request.url %></div> and this javascript <script type="text/javascript"> function select_all(id) { document.getElementById(id).focus(); } </script> This doesn't work. I'd like to know what's the simplest thing I should do to achieve what I want. I thought about changing the div to a text input or the text within to be a link, but ideally the content within should be read-only, non-editable, and non-clickable

• setfsuid() and python 2.5.4

  - by user331398

  Hi, I'm trying to use setfsuid() with python 2.5.4 and RHEL 5.4. Since it's not included in the os module, I wrapped it in a C module of my own and installed it as a python extension module using distutils. However when I try to use it I don't get the expected result. setfsuid() returns value indicating success (changing from a superuser), but I can't access files to which only the newly set user should have user access (using open()), indicating that fsuid was not truely changed. I tried to verify setfsuid() worked, by running it consecutively twice with the same user input The result was as if nothing had changed, and on every call the returned value was of old user id different from the new one. I also called getpid() from the module, and from the python script, both returned the same id. so this is not the problem. Just in case it's significant, I should note that I'm doing all of this from within an Apache daemon process (WSGI). Anyone can provide an explanation to that? Thank you

• How to hide URL from users when submitting this form?

  - by Camran

  I have a form with many many fields... When submitting these fields, I use the POST method which hides the actual variables passed along to the PHP page. However, I can't get rid of the complete link. Changing from GET to POST did make all the form fields invisible in the URL, but this part is still visible: mydomain.com/bin/query# I want it to be invisible, or say: mydomain.com/search I have mod_rewrite enabled so there is a possibility to do this with mod_rewrite I think, but I am new to mod_rewrite so I need your help... How should I hide this URL? If you need more input let me know...

• Initialise a wix CheckBox's check state based on a property?

  - by MauriceL

  How does one initalise a Wix check box based on the value of a property? So far, I've done the following: <Control Id="Checkbox" Type="CheckBox" X="0" Y="0" Width="100" Height="15" Property="CHECKBOX_SELECTION" Text="I want this feature" CheckBoxValue="1" TabSkip="no"> <Condition Action="hide">HIDE_CHECKBOX</Condition> <Condition Action="show">NOT HIDE_CHECKBOX</Condition> </Control> Currently I have two custom actions to set HIDE_CHECKBOX and CHECKBOX_SELECTION. The CHECKBOX_SELECTION custom action occurs immediately after the HIDE_CHECKBOX action. What I'm seeing is that HIDE_CHECKBOX is behaving correctly (ie. the checkbox is hidden) which suggests that I've got the ordering of custom actions correct, but CHECKBOX_SELECTION is not changing the check state of the check box. Is this a safe assumption? Also, I've confirmed that SELECTION is being set to '1' in the logs.

• Switching from php to python

  - by ts

  Hello I am trying to make a list of things which can be difficult/surprising to someone who is changing language from PHP to Python. so far i have rather short list: forget require / include, learn import (this was most difficult to me - to understand package - module - class - object hierarchy and its mapping to filesystem) you can't just upload file on server to have webpage (-mod_python, wsgi etc) learn the python way for use variable class names (new $class() vs import + getattr) / operator in python 2.x and all float-related horrors those were difficult to me, it takes few days before mind adapts a new paradigm after i found that there is few other areas which could be challenging for someone with (too) many years of php: everything is an object you have to live with exceptions array vs list, set, dictionary, tuple ... learn (effective) list comprehensions learn generators any other ideas / personal experiences ?

• How to create "lock" (stop updating of cells) in Excel?

  - by Oozi

  My question is pretty simple, but one to which I can't really find a solution myself. I use Excel quite frequently, but rarely the fancy stuff. Anyway, to the point: How do I create a dropmenu that will lock certain cells, rows or columns? (by lock I mean unable to change via hand and stops updating itself). Example: A1 = 5 B1 = A1 * 100 Can I "lock" the B1-cell, so that changing A1 will have no effect on B1 (Will remain at value 500)? I would preferably want to be able to "unlock" the cell as well, instead of simply making function into value. Is this possible? Thanks in advance!
