• How can I make a fixed hex editor?

  - by Kevin

  So. Let's say I were to make a hex editor to edit... oh... let's say a .DLL file. How can I edit a .DLL file's hex by using C# or C++? And for the "fixed part", I want to make it so that I can browse from the program for a specific .DLL, have some pre-coded buttons on the programmed file, and when the button is pressed, it will automatically execute the requested action, meaning the button has been pre-coded to know what to look for in the .DLL and what to change it to. Can anyone help me get started on this?

• jquery validation of controls

  - by Vinodtiru

  Hi , I am looking at validation of some text boxes for somethings like required, minlength, max length, email etc... I am able to get examples that work fine on submit button on page. I want to do this validation on a button click which will only raise a ajax request and not submit of page. On internet all the sample is found was with submit button. Is there a easy way to change this code a little bit o make it work for non submit button click or any new jquery or java plugin to do the same. I am using the jquery.validation.js for now. This works with submit buttons. Any kind of help with suggestion or help is appreciated. Thanks in advance.

• iPhone - Using javascritp to increase font of web view

  - by satyam

  i've a webview in my app. It has + and - buttons to increase and decrease the font. When I start the view, the text occupies whole 320 pixels width. I'm following the way mentioned in "http://stackoverflow.com/questions/589177/how-to-increase-font-size-in-uiwebview" I'm seeing the increase and decrease of font. But once the font size increases, text is not occupying full view. It won't occupy whole 320 pixels width. As and when text size increases, the width of final text in web view decreases slowly. Why? How to avoid it?

• How to include other controls in a scrollbar?

  - by Paperflyer

  I want to create a scrollview with a zooming control and a button next to the scrollbar. Sort of like the "tile window" button in XCode (top right corner of the editor), it should be in the same box that usually is used by the scrollbar only. Do you have an idea of how to approach this? I was thinking to use an NSScrollView and set the scrollbars to a custom subclass of NSScroller which includes the other widgets. What kinds of buttons use the same style as the scrollbar?

• Actionscript 3: foreach drawing object in movieclip

  - by Mathias

  Hey, I got a europe map designed in flash (1 movieclip, 1 frame, really simple), which contains the map as drawing objects directly inside the scene and in addition some specific countries as clickable buttons. So far it's working fine. What I need now is to make all the other drawing objects clickable without having to edit and script each object. I'm thinking about something like this (pseudo code): foreach(obj in MovieClip) { if(obj !typeof(Button)) { obj.addEventListener(MouseEvent.MOUSE_DOWN, genericClickListener); } } I just don't know the syntax how to achieve that. Could anybody give me a hint? Thanks, Mathias

• Changing value of a Numeric Stepper

  - by REDDY

  Hi, I am a newbie to Flex and programming. I am trying something where I have 2 Numeric Steppers. One numeric stepper holds values from 0-230 and the other from 0.00-0.99. My question is how to change the value of the first numeric stepper when the second numeric stepper goes from 0.99 to 0.00. Suppose the first numeric stepper has a value 10 and the second numeric stepper is being incremented continuously. As it reaches 0.99 and on mouse up on the up arrow, 10 should change to 11 and this numeric stepper goes to 0.00. Could anyone help me out with some code or suggestion? Thanks is advance, REDDY

• Use Javascript to copy Text from Label

  - by Josh

  Hello All- Label1 (asp.net control) is located inside Panel1 of my webpage and I have a button called bt. What is the Javascript to copy the Text from Label1 to the clipboard? Thanks, @ artlung, I placed the below code just outside of my form but inside the body. The last line of code I placed inside Panel1 of my form. Anything wrong with this code because nothing happens when I click the Copy to Clipboard button. <script language="JavaScript"> var clip = new ZeroClipboard.Client(); clip.addEventListener( 'mouseDown', function(client) { // set text to copy here clip.setText( document.getElementById('form1.Label1').value ); // alert("mouse down"); } ); clip.glue( 'd_clip_button' ); </script> The next line of code is above the script tags but inside Panel1 in my form <div id="d_clip_button">Copy To Clipboard</div>

• Embed Javascript Module within Flex application

  - by Crimson

  I have a large module written in JS which uses Canvas to draw and animate trees. This module was written for a product which is now being migrated to flex. Is there a way in flex to embed this JS module as is? Or would I have to rewrite the whole module in AS3 (shudder)? Further, if embedding is possible, would user interactions (mouse clicks) etc. work seamlessly? An example of the tree structure I am talking about can be found here - http://thejit.org

• Paypal subscription API - transaction variables not POSTed

  - by morpheous

  I am writing a payments system based around paypal, I am using the HTML 'API'. I am passing the following form fields to PayPal: 'rm' = 2 'return = http://www.example.com/payment-handler.php?token=sometoken Where 'token' is a token I generated. According to the paypal documentation, a return method (rm) of 2 indicates to Paypal that the transaction data be posted back to the callback url using the POST method. When processing items using 'buy_now' buttons, the transaction items are correctly POSTed to my callback url (payment-handler.php), but for 'subscribe' operations, although the callback url is called, no POST data is sent to the url, and also, the 'token' field is missing. Instead, there is a parameter called 'auth'. I cant see anything in the paypal docs about a 'auth' field - so I dont know whats generating it and if I can reliably using it. Can anyone shed some light on this?

• How to fix weird scrolling/alignment behavior when using keyboard in MenuStrip?

  - by bentsai

  I started noticing strange behavior when navigating the main toolbar of my Winforms application, and I don't know how to fix it. When I initially open the dropdown of the File menu, it looks like this: I begin to scroll down each item with the arrow keys, and everything is fine until I reach "Exit". As soon as I hit the down arrow key from "Log Off", or if I hit the up arrow key from "Open", the menu rearranges itself to look like this: I'm puzzled by this behavior. The menu still works, and from this point, if I start scrolling up, I can get the arrangement back to normal: A few observations: The menu still works. This doesn't happen when using the mouse. I have some code that toggles the Visible property of some of the menu items. I was able to modify what the arrangement was by playing around with this, but it was still messed up. Can anyone help me understand what is going on, and how to fix it?

• Curser control using Masked Text Box in C#

  - by George

  I seem to have asked this question twice ! I kept getting a message saying New Members can only add a new Question every 20 minutes, try again later !!! Sorry for the duplication ! Please ignore this one !! Thanks. In my app in C# I have several input fields that I need to capture. I need them to be of specific sizes and type and I have used masked Text Boxes for these. I have fields like name which is 20 text charachters long, and a certificate number which is 5 numeric characters with a preceding C etc. This works fine except with I click on a field with the mouse, the cursor does not go to the begining of the fild, or the end of any input text. Is there a way of allowing this to happen using Masked Text Box or will I have to use normal Text Box and do all the field validation manually ?

• Age verification forms and crawlers

  - by user333763

  I have created a website about some beer brand and had to include age verification page. The verification script is written in PHP and uses sessions to store verification variable. The script works the way that no matter form which link you will try to enter the website it will take you to the verification page first. The verification is very simple. There are 2 button: "I'm under 21" and "I'm over 21". If you click the latter, you can browse the website. After some time I discovered that the web crawlers are not able to get past verification page. I checked the website in Google webmaster tools and the only text content scanned was from the verification page. I read somewhere that crawlers are not able to submit form buttons, is it true? Considering the fact that age verification pages are useless anyways, maybe I should just leave it as a starting page but don't forbid going around it, e.g. from links to the subpages?

• Custom draw button using uxtheme.dll

  - by Javier De Pedro

  I have implemented my custom button inheriting from CButton and drawing it by using uxtheme.dll (DrawThemeBackground with BP_PUSHBUTTON). Everything works fine but I have two statuses (Normal and Pressed) which Hot status is the same. It means when the user places the cursor over the button it is drawn alike regardless the button status (Pressed or not). This is a bit confusing to the user and I would like to change the way the button is drawn in Pressed & Hot status. Does anybody know a way? I have also thought about custumizing the whole drawing but the buttons use gradients, borders, shadows, etc. So it is not easy to achive the same look&feel drawing everything by myself. Is there a way to find the source code of the dll or know how to do it? Thanks in advance. Javier

• IE7 resize problems

  - by moshe_ravid

  i have a page that contains content which need to be dynamically changed according to the current page size. in order to do that, during the onload event, i attach some JS function to the "onresize" window event. it looks like that: window.onresize = function() { //do something here... }; This is working fine in any browse, except IE7! These are the problems i'm having: It seems that in IE7, when i resize the window vertically only (i.e. clicking with the mouse on the bottom border, and drag it down), it does not fire the "onresize" event. sometimes, i get an infinite loop of "onresize" event, causing the browser to hang forever. I will appreciate any help with any of these issues. thanks, Moe

• iPhone - Bug using CADisplayLink and UIControls - bad to mix openGL and UIControls?

  - by Adam

  Having had problems using other methods, I've decided to stick with CADisplayLink to run my game loop. The animation is smooth now, but sometimes there's a problem where the buttons and other UI elements can't be used, can't be accessed by touch or changed programmatically. This includes UIButtons and UILabels. Has anyone encountered this before? Is it not a good idea in general to use interface builder and uicontrols on top of an OpenGL view? I've heard they don't play well together but haven't heard the reasons. Thanks!

• How to know when a pop-down menu needs to be closed

  - by Pieter

  I'm experimenting with pop-down menus (inside floating DIVs). Making them appear with onmouseover attributes is no problem, but I'm not sure how I can make the menu close properly. I figured the best way to know when to close the menu is wait until the mouse is no longer hovering over the HTML element that called the menu or the menu itself, then wait one second, and then close the menu. Is my idea something that can be implemented, perhaps with some jQuery? Or is there a better and more efficient alternative?

• How to intercept capture TAB key in WinForms application?

  - by Axarydax

  Hi, could you please help me with this one? I'm trying to capture Tab key in Windows Forms application and do a custom action on it. I have a Form with several listViews and buttons, I've set Form's KeyPreview property to true and when I press any other key than tab, my KeyDown event handler does get called. But that's not true with the Tab key - I don't receive WM_KEYDOWN message even in WndProc. Do I need to set each control inside my form - its TabStop property - to false? There must be a more ellegant way that that. Thanks.
