• C# Button Text Unicode characters.

  - by Fossaw

  C# doesn't want to put Unicode characters on buttons. If I put \u2129 in the Text attribute of the button, the button displays the \u2129, not the Unicode character, (example - I chose 2129 because I could see it in the font currently active on the machine). I saw this question before, link text, but the question isn't really answered, just got around. I am working on applications which are going all over the world, and don't want to install all the fonts, more then "don't want", there are that many that I doubt the machine I am working on has sufficient disk space. Our overseas sales agents supply the Unicode character "numbers". Is there another way forward with this? As an aside, (curiosity), why does it not work?

• Forcing images to not wrap

  - by Mohammad

  I can't touch the html theme but I have access to the css files. <div class="photos"> <img src="a.jpg" alt="" align="left" /> <img src="b.jpg" alt="" align="left" /> <img src="c.jpg" alt="" align="left" /> //align makes the images wrap </div> Unfortunately I can't remove align="left" from the images otherwise this CSS snippet would have done the job .photos{ white-space: nowrap; } .photos img{ display: inline; vertical-align: top; } Any ideas? Is it even possible to make these images line-up horizontally without using the force of a table and only with CSS? Many Thank in advance!

• Strange padding in Safari when using SVG images

  - by Naman Goel

  I thought I was having issues with margins but then on a closer look I found that SVGs are acting funky in Safari 6. I am building a simple Hexagon based website. Of course I used negative vertical margins to for a little overlap to 'inter-lock' the hexagons. And to save space I was using SVG images for the hexagons. It works great in chrome and firefox, but in Safari, there is a strange padding in the SVG images. I'm using simple img tags for the svg images. Everything works when I switch to PNG, but I'd prefer to stick to SVGs. Any insight? Can I perhaps delve into the SVG code and somehow fix the SVG problem in Safari? or is it some sort of bug, that I can do nothing about without browser sniffing?

• Stack allocation fails and heap allocation succeeds!! Is it possible??

  - by Prabhu

  Hello All, I have the following piece of snippet Class Sample { Obj_Class1 o1; Obj_Class2 o2;}; But the size of Obj_Class1 and Obj_Class2 is huge so that the compiler shows a warning "Consider moving some space to heap". I was asked to replace Obj_Class1 o1 with Obj_Class1* o1 = new Obj_Class1(); But I feel that there is no use of making this change as heap allocation will also fail if stack allocation fails. Am I correct? Or does it make sense to make this change ( other than suppressing the compiler warning ).

• Image gallery control for ASP.Net with filtering capabilities

  - by ks78

  I'm writing an ASP.Net application which needs to display a large number of thumbnails, preferably in a paginated format. These thumbnails will be stored on the server's hard disk, but will have their filenames listed in a SQL Server database. What I want to do is to be able to filter the images being displayed based on criteria within the database. I've looked at the NotesForGallery control, which I really like, but it doesn't seem to have a way to do that. --if I'm wrong, please correct me. Are there any other image gallery type controls, preferably free, that can do what I need? I'm hoping someone can recommend a control or solution that will point me in the right direction. Thanks in advance.

• lock file so that it cannot be deleted

  - by JoeCool

  I'm working with two independent c/c++ applications on Windows where one of them constantly updates an image on disk (from a webcam) and the other reads that image for processing. This works fine and dandy 99.99% of the time, but every once in a while the reader app is in the middle of reading the image when the writer deletes it to refresh it with a new one. The obvious solution to me seems to be to have the reader put some sort of a lock on the file so that the writer can see that it can't delete it and thus spin-lock on it until it can delete and update. Is there anyway to do this? Or is there another simple design pattern I can use to get the same sort of constant image refreshing between two programs? Thanks, -Robert

• Dynamic Spacer in ReportLab

  - by ptikobj

  I'm automatically generating a PDF-file with Platypus that has dynamic content. This means that it might happen that the length of the text content (which is directly at the bottom of the pdf-file) may vary. However, it might happen that a page break is done in cases where the content is too long. This is because i use a "static" spacer: s = Spacer(width=0, height=23.5*cm) as i always want to have only one page, I somehow need to dynamically set the height of the Spacer, so that it takes the "rest" of the space that is on the page as its height. Now, how do i get the "rest" of height that is left on my page?

• How do I find out if the variable is declared in Python?

  - by golergka

  I want to use a module as a singleton referenced in other modules. It looks something like this (that's not actually a code I'm working on, but I simplified it to throw away all unrelated stuff): main.py import singleton import printer def main(): singleton.Init(1,2) printer.Print() if __name__ == '__main__': pass singleton.py variable1 = '' variable2 = '' def Init(var1, var2) variable1 = var1 variable2 = var2 printer.py import singleton def Print() print singleton.variable1 print singleton.variable2 I expect to get output 1/2, but instead get empty space. I understand that after I imported singleton to the print.py module the variables got initialized again. So I think that I must check if they were intialized before in singleton.py: if not (variable1): variable1 = '' if not (variable2) variable2 = '' But I don't know how to do that. Or there is a better way to use singleton modules in python that I'm not aware of :)

• GetDiskFreeSpaceEx reports wrong number of free bytes

  - by rboorgapally

  __int64 i64FreeBytes unsigned __int64 lpFreeBytesAvailableToCaller, lpTotalNumberOfBytes, lpTotalNumberOfFreeBytes; // variables used to obtain // the free space on the drive GetDiskFreeSpaceEx (Manager.capDir, (PULARGE_INTEGER)&lpFreeBytesAvailableToCaller, (PULARGE_INTEGER)&lpTotalNumberOfBytes, (PULARGE_INTEGER)&lpTotalNumberOfFreeBytes); i64FreeBytes = lpTotalNumberOfFreeBytes; _tprintf(_T ("Number of bytes free on the drive:%I64u \n"), lpTotalNumberOfFreeBytes); I am working on a data management routine which is a Windows CE command line application. The above code shows how I get the number of free bytes on a particular drive which contains the folder Manager.capdir (it is the variable containing the full path name of the directory). My question is, the number of free bytes reported by the above code (the _tprintf statement) doesn't match with the number of free bytes of the drive (which i check by doing a right click on the drive). I wish to know if the reason for this difference?

• Windows Azure Table Storage LINQ Operators

  - by Ryan Elkins

  Currently Table Storage supports From, Where, Take, and First. Are there plans to support any of the other 29 operators? If we have to code for these ourselves, how much of a performance difference are we looking at to something similar via SQL and SQL Server? Do you see it being somewhat comparable or will it be far far slower if I need to do a Count or Sum or Group By over a gigantic dataset? I like the Azure platform and the idea of cloud based storage. I like Windows Azure for the amount of data it can store and the schema-less nature of table storage. SQL Azure just won't work due to the high cost to storage space.

• Windows API calls from assembly while minimizing program size

  - by takteek

  I'm trying to write a program in assembly and make the resulting executable as small as possible. Some of what I'm doing requires windows API calls to functions such as WriteProcessMemory. I've had some success with calling these functions, but after compiling and linking, my program comes out in the range of 14-15 KB. (From a source of less than 1 KB) I was hoping for much, much less than that. I'm very new to doing low level things like this so I don't really know what would need to be done to make the program smaller. I understand that the exe format itself takes up quite a bit of space. Can anything be done to minimize that? I should mention that I'm using NASM and GCC but I can easily change if that would help.

• Apache Prefork Configuration

  - by user1618606

  I'm newbie on VPS configuration. So, I've installed apache, php and mysql and now I need to know how to configure Prefork to optimize Apache. The system configuration is: CPU Cores 2 x 2 Ghz @ 4 Ghz RAM Memory 2304 MB DDR3 Burst Memory 3 GB DDR3 Disk Space 30 GB SSD Bandwidth 3 TB SwitchPort 1 Gbps Actually, after linux, mysql, apache and php, there are 250 MB memory in use. Well, I don't have idea to calculate. I saw in some websistes, some vars like: KeepAlive On KeepAliveTimeout 1 MaxKeepAliveRequests 100 StartServers 15 MinSpareServers 15 MaxSpareServers 15 MaxClients 20 MaxRequestsPerChild 0 or StartServers 2 MaxClients 150 MinSpareThreads 25 MaxSpareThreads 75 ThreadsPerChild 25 MaxRequestsPerChild 0 How I could to do: Prefork or worker? Where and how the vars are placed? In httpd.conf? Big hug, Claudio.

• Python regular expression help

  - by dlw

  Hi SO, I can't seem to create the correct regular expression to extract the correct tokens from my string. Padding the beginning of the string with a space generates the correct output, but seems less than optimal: >>> import re >>> s = '-edge_0triggered a-b | -level_Sensitive c-d | a-b-c' >>> re.findall(r'\W(-[\w_]+)',' '+s) ['-edge_0triggered', '-level_Sensitive'] # correct output Here are some of the regular expressions I've tried, does anyone have a regex suggestion that doesn't involve changing the original string and generates the correct output >>> re.findall(r'(-[\w_]+)',s) ['-edge_0triggered', '-b', '-level_Sensitive', '-d', '-b', '-c'] >>> re.findall(r'\W(-[\w_]+)',s) ['-level_Sensitive'] Thanks -- DW

• Why does my PDF ask for a password after being retrieved from Visual SourceSafe?

  - by Schnapple

  PREFACE: Yes we're moving away from VSS in the next few months. One of my web projects contains, as one of its files, a PDF. The PDF on our QA site is being pulled from VSS. A QA tester recently told me he's being prompted for a password when he tries to open it. VSS says the file I have on disk is different than the one it has, so I updated it, but afterwards it's still being shown as different. So basically VSS is mangling my PDF and the results are so wobbly that Adobe Acrobat Reader is confused and thinks it has a password. I've tried adding it as Auto-Detect and as Binary. Same results. Why does my PDF ask for a password after being retrieved from Visual SourceSafe and how can I prevent it?

• WPF Template: AdornedElement not showing!

  - by Tau Sick

  I want to add some elements to a TextBox by using a Template with the extra elements and the original TextBox inserted in the right spot. I'm trying to use the AdornedElementPlaceholder just like you would do when making a Validation.ErrorTemplate But the AdornedElement is not showing up. I have simplified the example as much as possible: <TextBox Text="Border me with my Template"> <TextBox.Template> <ControlTemplate TargetType="{x:Type TextBox}"> <Border BorderBrush="Green" BorderThickness="1"> <AdornedElementPlaceholder/> </Border> </ControlTemplate> </TextBox.Template> </TextBox> The result is just a green box around the space that should be my textbox!

• Regexp for selecting spaces between digits and decimal char

  - by Tirithen

  I want to remove spaces from strings where the space is preceeded by a digit or a "." and acceded by a digit or ".". I have strings like: "50 .10", "50 . 10", "50. 10" and I want them all to become "50.10" but with an unknown number of digits on either side. I'm trying with lookahead/lookbehind assertions like this: $row = str_replace("/(?<=[0-9]+$)\s*[.]\s*(?=[0-9]+$)/", "", $row); But it does not work...

• What Windows editor has CORRECT EOL whitespace handling?

  - by blueshift

  I'm looking for a Windows text editor for programming that handles EOL whitespace CORRECTLY, which for my idea of correct means: Strip all EOL whitespace on save, EXCEPT on lines that I haven't edited. This is to minimise the amount of EOL whitespace evil in my world, but not pollute SCM diff/blame with whitespace-only fixes (I have to deal with old / other people's code). I have played with TextPad, Notepad++, Kodomo Edit and Programmer's Notepad 2, and found all of them lacking. Also: I don't get along with vi, and I am unsure about Emacs on Windows. @Matti Virkkunen: I could mess with diff, but I want to fix the problem, not the symptoms. Fixing diff means all my, others, and server side diff tools need to be fixed, and doesn't fix space/noise/hash change issues in SCM. Example pet hate using that system: "update" tells me a file has changed. Diff shows no changes.

• Looking for collaboration tool/platform to synergize with my clients in all phases.

  - by Kabeer

  Hello. I am a consultant and will be working with geographically distant clients. I am looking for a solution to collaborate with my clients effectively in all the phases of the projects (architecture, requirements, design, construction, testing, deployment, maintenance). My hunt is for something in the open source (and preferably free) space and also on .Net platform. I need to record my communication with the clients and with growing no. of clients I should not miss out capturing any information. Please recommend.

• Restoring Mac-bootcamp-windows-partition image to Windows machine

  - by jpwagner

  Hi, I'm running Windows XP sp3 on my mac using bootcamp. Objective: I'd like to move this partition to a windows machine. This is what I tried: 1. create image using winclone 2. restore drive to disk partition on windows machine using paragon 3. reboot from new partition Results: it attempts to boot in XP (windows flag and progress bar load screen) but then gives me the old BSOD. safe mode just hangs while loading. (I then uninstalled KB977165 on a hunch, but that did nothing to help the issue.) Any ideas, advice, etc would be greatly appreciated. Thanks!

• memory of drawables, is it better to have resources inside APK, outside APK or is it the same for me

  - by Daniel Benedykt

  Hi I have an application that draws a lot of graphics and change them. Since I have many graphics, I thought of having the images outside the APK, downloaded from the internet as needed, and saved on the files application folder. But I started to get outOfMemory exceptions. The question is: Does android handle memory different if I load a graphic from APK than if I load it from 'disk'? code using APK: topView.setBackgroundResource(R.drawable.bg); code if image is outside APK: Drawable d = Drawable.createFromPath(pathName); topView.setBackgroundDrawable(d); Thanks Daniel

• Programming a loopback-device consisting of several files in Linux

  - by dubbaluga

  Hej, it is relatively easy to use a file for emulating a block-device using losetup in Linux: http://www.walkernews.net/2007/07/01/create-linux-loopback-file-system-on-disk-file/ Can anyone please give me a hint on what to look for in case I want to program my own block-device which is based on several files I'm taking content from? For your understanding, I would like to let's say take bytes 1-500 and 1.000-3.000 from file1 and bytes 501-999 and bytes 3.001 to 5.000 from file2 to offer them as a combined block-device. My prefered programming language is Python and I want to write my program in user-space as much as possible. For Windows I found such an implementation. It's called FileDisk and HttpDisk and it can be found here: http://www.acc.umu.se/~bosse/ Thanks in advance and regards, Rainer

• Code Golf: Phone Number to Words

  - by Nick Hodges

  Guidelines for code-golf on SO We've all seen phone numbers that are put into words: 1-800-BUY-MORE, etc. What is the shortest amount of code you can write that will produce all the possible combinations of words for a 7 digit US phone number. Input will be a seven digit integer (or string, if that is simpler), and assume that the input is properly formed. Output will be a list of seven character strings that For instance, the number 428-5246 would produce GATJAGM GATJAGN GATJAGO GATJAHM GATJAHN GATJAHO and so on..... Winning criteria will be code from any language with the fewest characters that produce every possible letter combination. Additional Notes: To make it more interesting, words can be formed only by using the letters on a North American Classic Key Pad phone with three letters per number as defined here.That means that Z and Q are excluded. For the number '1', put a space. For the number '0', put a hyphen '-' Bonus points awarded for recognizing output as real English words. Okay, not really. ;-)

• Xcode: code loses syntax coloring

  - by ColorMeFamous

  I find that in various situations Objective-C code in Xcode 3.1 (Leopard) can fail to get appropriate syntax coloring after typing or lose coloring that it had. This isn't just a "refresh" issue with new custom symbols -- but affects Cocoa framework symbols as well. Sometimes CMD-a to select all text on the code page will make the coloring (re)appear, sometimes double-clicking on a line to select it will work, sometimes I have to add/delete a space in a symbol to get that symbol to (re)color. Rebuilding, or closing/reopening the project may or may not work. Is this a known issue with Xcode? For something so annoying to me, I'm not finding the plentiful discussions of it on SO and elsewhere I'd expect. And is there any command to force global syntax recoloring?

• Database query optimization

  - by hdx

  Ok my Giant friends once again I seek a little space in your shoulders :P Here is the issue, I have a python script that is fixing some database issues but it is taking way too long, the main update statement is this: cursor.execute("UPDATE jiveuser SET username = '%s' WHERE userid = %d" % (newName,userId)) That is getting called about 9500 times with different newName and userid pairs... Any suggestions on how to speed up the process? Maybe somehow a way where I can do all updates with just one query? Any help will be much appreciated! PS: Postgres is the db being used.
