• How to make autocompleting textbox in vb6 like this one?

  - by Amit Kumar Jha

  hey all, well i want to have an autocompleting textbox like the one in the image below: this screenshot is from an accounting software. whenever the user focuses on a textbox and starts typing something the suggestions just popup under the control (as seen in the image under the Purc type textbox).This autosuggest functionality even works in the cells of the grid shown in the picture.Moreover the fields in which this autosuggest is enabled allows only values from the autosuggest list to be filled up and nothing else. i want to emulate similar functionality in my app in vb6. so if you could please guide me in the right direction i would be very grateful. thanks in advance to all those who take out time to reply.

• I have a question about URI templates in WCF Services

  - by Debby

  I have a web service with following operation contract and my service is hosted at http://localhost:9002/Service.svc/ [OperationContract] [WebGet(UriTemplate = "/Files/{Filepath}")] Stream DownloadFile(string Filepath); This web service would let users download file, if the proper filepath is provided (assuming, I somehow find out that proper filepath). Now, I can access this service from a browser by typing, http://localhost:9002/Service.svc/Files/(Filepath} If {filepath} is some simple string, its not a problem, but I want to send the location of the file. Lets us say users want to download file C:\Test.mp3 on the server. But how can I pass C:\Test.mp3 as {Filepath}? I get an error when I type http://localhost:9002/Service.svc/Files/C:\Test.mp3 in the browser. I am new to web services and find that this community is the quickest way to get answers to my questions.

• the commands ls and get of ftp are not working in vmware

  - by mnish

  Hi, Iam using vmware player version 3.1 to boot a minix 3 os image. After booting the minix os I want to get some files from a server using ftp. the ftp connection to the server works but when i use the commands "ls" or "get" nothing happens except it says "200 PORT command successful" and it hanges in there. The only thing i can do after typing ls+enter or get+enter is to exit the ftp by using ctrl+c. If anyone knows a solution to this? please help. Thank you

• Send keystrokes to TextBox

  - by tanascius

  I have a derived TextBox where I intercept the userinput to manipulate it. However I have to preserve the original typed input. So my idea was to hold an inner TextBox within my derived class and send the user's input to that TextBox before manipulating it. The reason for this approach is that I do not want to take care of all this special actions like: typing something, ctrl+a, [del], type something else, [backspace] and so on ... However I do not know how to send a single keystroke (keycode, ascii, char) to a TextBox. Maybe you have another idea without an inner TextBox at all? Thank you!

• scala REPL is slow on vista

  - by Jacques René Mesrine

  I installed scala-2.8.0.RC3 by extracting the tgz file into my cygwin (vista) home directory. I made sure to set $PATH to scala-2.8.0.RC3/bin. I start the REPL by typing: $ scala Welcome to Scala version 2.8.0.RC3 (Java HotSpot(TM) Client VM, Java 1.6.0_20). Type in expressions to have them evaluated. Type :help for more information. scala> Now when I tried to enter an expression scala> 1 + 'a' the cursor hangs there without any response. Granted that I have chrome open with a million tabs and VLC playing in the background, but CPU utilization was 12% and virtual memory was about 75% utilized. What's going on ? Do I have to set the CLASSPATH or perform other steps.

• How to implement buffering with timeout in RX

  - by Gaspar Nagy

  I need to implement an event processing, that is done delayed when there are no new events arriving for a certain period. (I have to queue up a parsing task when the text buffer changed, but I don't want to start the parsing when the user is still typing.) I'm new in RX, but as far as I see, I would need a combination of BufferWithTime and the Timeout methods. I imagine this to be working like this: it buffers the events until they are received regularly within a specified time period between the subsequent events. If there is a gap in the event flow (longer than the timespan) it should return propagate the events buffered so far. Having a look at how Buffer and Timeout is implemented, I could probably implement my BufferWithTimeout method (if everyone have one, please share with me), but I wonder if this can be achieved just by combining the existing methods. Any ideas?

• How does Twitter for iPhone bookmarklet work?

  - by Igor Zevaka

  Twitter client (formerly Tweetie) allows you to define a bookmarklet in Safari that launches the app. I want to know which iPhone API allows you to register the protocol specifier (or whatever it's called) - in this case "tweetie:" - in order for this bookmarklet to work. The instructions can be found here and the bookmarklet itself is below. javascript:window.location='tweetie:'+window.location Clicking the above bookmark is the same as typing in "tweetie:http://google.com" into the address bar. This is obviously supported on the OS/Browser level, much the same as tel: URIs. Am I correct in understanding that developers can add arbitrary URI protocol specifiers as a part of app installation?

• How can I debug this web service http handler?

  - by baron

  Hello everyone, I am building a Httphandler following these instructions here It manipulates HTTP POST and HTTP GET. I have a client with two buttons two POST and GET. After i've tested and happy everythings working I move it from localhost to IIS. Now when I do this I get an exception in the POST handler code. How on earth can I debug this code line by line? I managed to do this awhile ago, I thought it was by attaching to process but I can't work it out. I can emulate GET just by typing address in browser, post im not sure about. I've tried telnetting and sending it from there but haven't had any luck.

• What features of interpreted languages can a compiled one not have?

  - by sub

  Interpreted languages are usually more high-level and therefore have features as dynamic typing (including creating new variables dynamically without declaration), the infamous eval and many many other features that make a programmer's life easier - but why can't compiled languages have these as well? I don't mean languages like Java that run on a VM, but those that compile to binary like C(++). I'm not going to make a list now but if you are going to ask which features I mean, please look into what PHP, Python, Ruby etc. have to offer. Which common features of interpreted languages can't/don't/do exist in compiled languages? Why?

• Xcode, Dev Docs Search Field Loosing Focus?

  - by fuzzygoat

  I am having a strange issue with the developer documentation (which i have only noticed after installing Xcode 3.2.3). My problem is that as you type in the search field (upper right) it looses focus and immediately starts looking for the first few letters you type. For example if you looking for "NSObject" you start typing "NSO" and as you type the field looses focus the last 5 characters "bject" just give beeps as you need to reselect the field to type extra characters. Has anyone else come across this or know what the problem might be? cheers Gary.

• jquery autocomplete on button click get hidden value

  - by gabriel

  using jquery autocomplete, we get hidden value by calling .result function like this $("#suggest").result(function(event, data, formatted) { $('#hidden').val(data[1]); }); This is only useful when we selected the option from autosuggest list and press enter. What i need is that i enter the option by typing the complete word without selecting it and clicking on Ok button? but i am always getting empty. <input type="text" id="suggest" /> <input type="button" value="Ok" onclick="GetValue()" /> <input type="hidden" id="hidden"/> function GetValue() { //get hidden field value - getting empty var hid=document.getElementById('hidden').value; }

• Limiting input to specified regexp with uppercase chars in IE

  - by pixelboy

  I'm trying to limit what our users will be able to type in inputs, using javascript/jquery. Problem is, I have to limit this to Uppercase chars only, and numbers. Here's what I coded previously : $(input).keydown(function(e){ if ($(input).attr("class")=="populationReference"){ var ValidPattern = /^[A-Z_0-9]*$/; var char = String.fromCharCode(e.charCode); if (!ValidPattern.test(char) && e.charCode!=0){ return false; e.preventDefault(); } } }); If Firefox supports charCode, IE doesn't. How then, could I test if the user is typing uppercase or lowercase characters ? Thanks for any help !

• Condensing multiple else if statements, referencing them from a table?

  - by Haskella

  Hi I'm about to type some 500 else if statements into my code (PHP) which have the exact same coding each: if (color=White); rgb = 255-255-255; print rgb; else if (color=Black); rgb = 0-0-0; print rgb; else if (color=Red); rgb = 255-0-0; print rgb; else if (color=Blue); rgb = 0-0-255; print rgb; [the list keeps going] I also (luckily) have a table that displays the color in the first column and rgb value in the next column for 500 of them... how do I use this to save time typing all those else if statements? Some how I have to reference the table file (made in excel, I'm guessing I'll have to save it as .csv?)

• What is the difference between these task definition syntaxes in gradle?

  - by bergyman

  A) task build << { description = "Build task." ant.echo('build') } B) task build { description = "Build task." ant.echo('build') } I notice that with type B, the code within the task seems to be executed when typing gradle -t - ant echoes out 'build' even when just listing all the various available tasks. The description is also actually displayed with type B. However, with type A no code is executed when listing out the available tasks, and the description is not displayed when executing gradle -t. The docs don't seem to go into the difference between these two syntaxes (that I've found), only that you can define a task either way.

• Is it possible to register a user and submit a comment with one form with Wordpress?

  - by zack

  Is it possible to do both registering for an account and submit a comment at the same time? I want the user to be able to do this all on one page to ecourage the registration rather than be discouraged about typing something, not realizing they had to be registered and thus having to leave the page. I think that this could be done by adding register user action to the submit comment action, but not sure how to do it with the prebuilt wordpress add_action or do_action functions. Has anyone tried this, or know of any plug-ins that do this already? I searched but couldn't find anything helpful. Thanks.

• RewriteCond to change displayed host, but not server

  - by coneybeare

  Typing out the title to this leads me to believe this might not be possible due to security concerns, but I will ask anyway. I have shortcode support running on my server, lets call it xx.yy I want it so when a user sends a request to xx.yy, it just changes the displayed host to another valid domain running on the same box. I have this so far (lets the server know to accept requests from xx.yy): RewriteCond %{HTTP_HOST} ^.*xx.yy [NC] RewriteRule ^/(.*)$ http://127.0.0.1:<PORT_OMITTED>%{REQUEST_URI} [P,QSA,L] RewriteCond %{HTTP_HOST} ^.*mysite.com [NC] RewriteRule ^/(.*)$ http://127.0.0.1:<PORT_OMITTED>%{REQUEST_URI} [P,QSA,L] It works, and it directs the traffic into my app, but the url says http://xx.yy when I would rather it say http://mysite.com I know i could redirect to http://mysite.com instead of 127.0.0.1, but I have 4 parallel boxes of mysite.com and going back out to DNS to maybe go to another box seems like a waste when I am already here. Also, I am not sure how POST requests would work like that. What can I do?

• C: Pointers to any type?

  - by dragme

  I hear that C isn't so type-safe and I think that I could use that as an advantage for my current project. I'm designing an interpreter with the goal for the VM to be extremely fast, much faster than Ruby and Python, for example. Now I know that premature optimization "is the root of all evil" but this is rather a conceptual problem. I have to use some sort of struct to represent all values in my language (from number over string to list and map) Would the following be possible? struct Value { ValueType type; void* value; } I would store the actual values elsewhere, e.g: a separate array for strings and integers, value* would then point to some member in this table. I would always know the type of the value via the type variable, so there wouldn't be any problems with type errors. Now: Is this even possible in terms of syntax and typing?

• Are the built-in images in iPhone documented, and is there a list of their names somewhere?

  - by Alex Gosselin

  I discovered somewhat by accident that if you make a UIButton in Interface Builder and type in Plus in the image field, a + image appears for the button. A similar result comes from typing Minus. I am wondering if this is a bug, or if there is some way the poor programmers can access the built-in general GUI images from other apple apps, such as the green +, the red -, the detail disclosure chevron, the big red "Delete Contact" or similarly styled button, etc. Has anyone else encountered this, or know where to access these things in Xcode? It makes sense to me that they should be usable, cause the Apple HIG seems to be all about making things recognizable and intuitive, and using them the way other apps use them.

• .htaccess not working in subfolder

  - by Staffan Estberg

  Hello, I have a couple of sites that are currently under development and I've put them under a specific subfolder for clients/co-workers to view - "http://dev.staffanestberg.com/site-name/". I've run into some problems getting the sites working with .htaccess. I can reach the index page by typing in the url for a site folder but neither img/style/js/etc linking or page rewriting works. Looking for a solution to this, Apache's "RewriteBase" seems to be the most likely one, however I can't get it to work. Tried RewriteBase http://dev.staffanestberg.com/site-name/ RewriteBase /site-name What would be the correct method? Thanks in advance, -Staffan

• ASP.Net Roles: Page-Level Security Question

  - by jlrolin

  We're currently in the process of re-creating a brand new security model that dwarfs our existing process. Right now, we plan on grabbing a user's roles during the login process and then using a Base Page class to check if the user has the role of the corresponding page the user is navigating to. We can limit the menu's options by the user's roles as well, but we have had problems with users navigating to pages in our system by typing them in or having old bookmarks. Obviously, we need some sort of page level access. A simple function in our Base Page class that checks the role in the Arraylist against the page's assigned role would work, but I was wondering if there was any built-in functionality to support this or a cleaner solution possibly.
