• how to write barcode in html format when using tcpdf

  - by JewelThief

  I am using TCPDF to generate PDF file using following command $pdf-writeHTML($htmlcontent, true, 0, true, 0); TCPDF also provides a way to create barcode with following commands $pdf-Cell(0, 0, 'C39+', 0, 1); $pdf-write1DBarcode('Code 39', 'C39+', '', '', 80, 15, 0.4, $style, 'N'); $pdf-Ln(); I want to be able to write barcode as part of the HTML code above. Is there easy way? I can potentially call a barcode image inthe writeHTML code above, but not sure how to use above barcode function ( or any in TCPDF) which would allow me to create image and then get that image into HTML generation

• VB.net Net after load event?

  - by themaninthesuitcase

  I need some way of knowing when a form has finished loading. My reasoning is I have a 2nd form that is loaded when this form loads. The code for this is called from form1.load. Form2 is currently being displayed behind form1 as I am guessing form1 calls an activate or similar at the end of the load so any Activate, BringToFront etc calls on from2 are over ridden. If you look at the code below I have tried adding frmAllocationSearch.Activate, frmAllocationSearch.BringToFront and Me.SendToBack after the call to ShowAlloactionSearchDialog() but these are all wasted as something is happening after the load event is fired to bring Me to the front. Code is: Private Sub Allocation_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load ShowAlloactionSearchDialog() End Sub Private Sub ShowAlloactionSearchDialog() If frmAllocationSearch Is Nothing OrElse frmAllocationSearch.IsDisposed Then frmAllocationSearch = New AllocationSearch frmAllocationSearch.MdiParent = Me.MdiParent frmAllocationSearch.Info = Me.Info frmAllocationSearch.Top = Me.Top frmAllocationSearch.Left = Me.Left + Me.Width - frmAllocationSearch.Width frmAllocationSearch.AllocationWindow = Me frmAllocationSearch.Show() Else If frmAllocationSearch.WindowState = FormWindowState.Minimized Then frmAllocationSearch.WindowState = FormWindowState.Normal frmAllocationSearch.Activate() End If End Sub

• Unable to view dialog box in win ce

  - by ame

  I have a win32 application (over 100 source files large) which i need to port to Win CE. I disabled the unsupported functions (such as non client area functions) and compiled the code on a Win CE platform. Now when i run it on my hardware device, I was able to resize the first couple of dialog screens to show up satisfactorily on the LCD. However there is a dialog box that has 2 option buttons and opens a new dialog box based on the choice. I am unable to view the new dialog box. Also, the close (X) button of the parent dialog box is not there and instead shows a question mark (?). I tried resizing the dialog box in the win32 code's resource compiler and it still showed up fine thus telling me that the problem did not lie with the bitmaps. I think there might be some issue with hiding the first dialog box or opening 2 at the same time. please help me. I did not code the win32 version myself and hence i am unable to locate the problem.

• Blackberry - How to get Field Labels from PIMItem

  - by Taha

  How can we get Field Labels from PIMItem. The following code is with PIMList String label = pimList.getAttributeLabel( blackBerryContact.getAttributes(Contact.TEL, i)); But i have PIMItem. There is a method PIMItem.getPIMList() which returns null for me in the code below. THE API at http://www.blackberry.com/developers/docs/5.0.0api/index.html says "getPIMList() Gets the PIMList associated with this item." Below is sample code that i am trying to achive - // Load the address Book and allow the user to select a contact BlackBerryContactList contactList = (BlackBerryContactList) PIM.getInstance().openPIMList(PIM.CONTACT_LIST,PIM.READ_ONLY); PIMItem userSelectedContact = contactList.choose(); // Now get the Field labels for contact numbers for userSelectedContact

• Using OnNcHItTest for a CWnd not CDialog

  - by dev ray

  I have a CWnd Derived object used in a dialog. I need to be able to drag it anywhere in the dialog. I have a code overriding OnNCHitTest for moving a dialog dragging it from a place other than the title bar. Is there any equivalent code to do the same to move this CWnd. The following code isnt working. UINT CBaseSliderBtn::OnNcHitTest(CPoint point) { UINT ret=CWnd::OnNcHitTest( point ); if (ret == HTCLIENT) return HTCAPTION; } If this isn't the right way, please suggest other optimum method to drag the slider. Thanks

• How to use TDD in a not very "Testy" environment

  - by dbemerlin

  I work in a company where OOP is... well, not fobidden, but at least frowned upon as "too complex". My coworkers write lots of 100+ lines functions and they are usually all in a "funcs.inc.php" or "something.inc.php", if they use any functions at all, often they don't since copy-paste is faster. I would love to start using TDD at least for the code i write but as i have to interface with their code i can't see how to begin. It's not legacy code as they are actively developing it and i don't want to modify their code as i don't want to provoke conflicts. Which approach would you suggest, except for changing the company?

• Remove HTTP headers from a raw response

  - by Ed

  Let's say we make a request to a URL and get back the raw response, like this: HTTP/1.1 200 OK Date: Wed, 28 Apr 2010 14:39:13 GMT Expires: -1 Cache-Control: private, max-age=0 Content-Type: text/html; charset=ISO-8859-1 Set-Cookie: PREF=ID=e2bca72563dfffcc:TM=1272465553:LM=1272465553:S=ZN2zv8oxlFPT1BJG; expires=Fri, 27-Apr-2012 14:39:13 GMT; path=/; domain=.google.co.uk Server: gws X-XSS-Protection: 1; mode=block Connection: close <!doctype html><html><head>...</head><body>...</body></html> What would be the best way to remove the HTTP headers from the response in C#? With regexes? Parsing it into some kind of HTTPResponse object and using only the body? EDIT: I'm using SOCKS to make the request, that's why I get the raw response.

• In vim is there a way to delete without putting text in the register?

  - by Edward Tanguay

  Using vim I often want to replace a block of code with a block that I just yanked. But when I delete the block of code that is to be replaced, that block itself goes into the register which erases the block I just yanked. So I've got in the habit of yanking, then inserting, then deleting what I didn't want, but with large blocks of code this gets messy trying to keep the inserted block and the block to delete separate. So what is the slickest and quickest way to replace text in vim? is there a way to delete text without putting it into the register? is there a way to say e.g. "replace next word" or "replace up to next paragraph" or is the best way to somehow use the multi-register feature?

• How do I edit an interface builder object programmatically?

  - by Evelyn

  I created a label using Interface Builder, and now I want to set the background color of the label using code instead of IB's color picker. (I want to do this so that I can define the color using RGB and eventually change the colorspace for the label.) I'm in cocoa. How do I edit the attributes of an IB object using code? My code looks like this: //.h file #import <UIKit/UIKit.h> @interface IBAppDelegate : NSObject { UILabel *label; } @property (nonatomic, retain) IBOutlet UILabel *label; @end //.m file #import "IBAppDelegate.h" @implementation IBAppDelegate @synthesize label; (memory stuff...) @end

• Tracking a Flash banner advert using clickTag and Google Analytics

  - by alistair.mp

  Hello. I'm trying to find out if there is a way of using clickTag and Google Analytics to track outgoing banner clicks. clickTag code: on (release) { if (clickTAG.substr(0,5) == "http:") { getURL(clickTAG); } } Maybe someone can tell me whether the following would work: on (release) { if (clickTAG.substr(0,5) == "http:") { getURL("javascript:pageTracker._trackPageview('/somebannerad');"); getURL(clickTAG); } } but I would ideally like a solution that worked with the standard clickTag code and didn't involve changing any code in the flash file. Anyone have any ideas? Thanks

• Selecting a UserControl from XAML

  - by kmontgom

  I'm working on a problem right now where I need to embed a UserControl inside another UserControl. But, I need to determine at runtime which embedded UserControl to instantiate. This implies to me that some form of data binding and/or template selection mechanism has to be invoked, but I'm not sure how to proceed with the pure XAML approach. If I was to do this with code, I would define some sort of container control in the parent UserControl, and then in the code-behind, implement some logic which would instantiate the appropriate child UserControl and then insert it as Content into the specified container in the parent UserControl. Can this be done using only XAML, or is some sort of code-behind required?

• Implicit and Explicit implementation of interface.

  - by Amby

  While working on a upgrade i happened to come across a code like this. interface ICustomization { IMMColumnsDefinition GetColumnsDefinition(); } class Customization : ICustomization { private readonly ColumnDefinition _columnDefinition; //More code here. public ColumnsDefinition GetColumnsDefinition() { return _columnDefinition; } ColumnsDefinition ICustomization.GetColumnsDefinition() //redundant { return GetColumnsDefinition(); } } My question is: Is there any need/use of 'explicit' implementation of interface in this piece of code? Will it create any problem if i remove the method (explicit implementation of interface) that i have marked "redundant" above? PS: I understand that explicit implementation of interface is very important, and it can be used when we need to give access to a method at interface level only, and to use two interface with same signature of method.

• importing same module more than once

  - by wallacoloo

  So after a few hours, I discovered the cause of a bug in my application. My app's source is structure like: main/ __init__.py folderA/ __init__.py fileA.py fileB.py Really, there are about 50 more files. But that's not the point. In main/__init__.py, I have this code: from folderA.fileA import * in folderA/__init__.py I have this code: sys.path.append(pathToFolderA) in folderA/fileB.py I have this code: from fileA import * The problem is that fileA gets imported twice. However, I only want to import it once. The obvious way to fix this (to me atleast) is to change certain paths from path to folderA.path But I feel like Python should not even have this error in the first place. What other workarounds are there that don't require each file to know it's absolute location?

• How can I pass data from an aspx page to an ascx modal popup?

  - by Erick B

  I'm fairly new to ASP.NET and trying to learn how things are done. I come from a C# background so the code-behind portion is easy, but thinking like a web developer is unfamiliar. I have an aspx page that contains a grid of checkboxes. I have a button that is coded via a Button_Click event to collect a list of which rows are checked and create a session variable out of that list. The same button is referenced (via TargetControlID) by my ascx page's ModalPopupExtender which controls the panel on the ascx page. When the button is clicked, the modal popup opens but the Button_Click event is never fired, so the modal doesn't get its session data. Since the two pages are separate, I can't call the ModalPopupExtender from the aspx.cs code, I can't reach the list of checkboxes from the ascx.cs code, and I don't see a way to populate my session variable and then programmatically activate some other hidden button or control which will then open my modal popup. Any thoughts?

• Cannot hide a UIButton

  - by Neurofluxation

  Hey again, I have the following code: visitSite.hidden = YES; For some reason, when I click a UIButton and call this piece of code, the visitSite button does not hide.

• How to create custom get and set methods for Linq2SQL object

  - by optician

  I have some objects which have been created automatically by linq2SQL. I would like to write some code which should be run whenever the properties on these objects are read or changed. Can I use typical get { //code } and set {//code } in my partial class file to add this functionality? Currently I get an error about this member already being defined. This all makes sense. Is it correct that I will have to create a method to function as the entry point for this functionality, as I cannot redefine the get and set methods for this property. I was hoping to just update the get and set, as this would mean I wouldn't have to change all the reference points in my app. But I think I may just have to update it everywhere.

• Trouble Emitting Object Array using Reflection.Emit

  - by JoeGeeky

  I am trying to Emit what I thought would be a simple object array that would result in code similar to the below example object[] parameters = new object[] { a, b, }; When I write the above code in C# using VS, I get the following IL. As expected this works. .locals init ( [0] object[] parameters, [1] object[] CS$0$0000) However, when I try and Emit IL directly, I only ever get a one index init array. Can someone help tell me where I've gone wrong here? Here is the Emit code I'm using: int arraySize = 2; LocalBuilder paramValues = ilGenerator.DeclareLocal(typeof(object[])); paramValues.SetLocalSymInfo("parameters"); ilGenerator.Emit(OpCodes.Ldc_I4_S, arraySize); ilGenerator.Emit(OpCodes.Newarr, typeof(object)); ilGenerator.Emit(OpCodes.Stloc, paramValues); Here is the resulting IL: .locals init ( [0] object[] objArray) The rest of the resulting IL is identical between the two solutions, but for some reason the .locals init is different.

• Java for each vs regular for -- are they equivalent?

  - by polygenelubricants

  Are these two constructs equivalent? char[] arr = new char[5]; for (char x : arr) { // code goes here } Compared to: char[] arr = new char[5]; for (int i = 0; i < arr.length; i++) { char x = arr[i]; // code goes here } That is, if I put exactly the same code in the body of both loops (and they compile), will they behave exactly the same??? Full disclaimer: this was inspired by another question (Java: are these 2 codes the same). My answer there turned out not to be the answer, but I feel that the exact semantics of Java for-each has some nuances that needs pointing out.

• [PHP] DOMDocument load on a page returning 400 Bad Request status

  - by PeteWilliams

  Hiya, I'm trying to use the Last.fm API for an application I'm creating, but am having some problems with validation. If an API request gives an error it returns a code and message in the response XML like this: <lfm status="failed"> <error code="6">No user with that name</error> </lfm> However, the request also returns an HTTP status of 400 (or in some cases 403) which DOMDocument considers an error and so then refuses to parse the XML. Is there any way round this, so that I can retrieve the error code and message? Thanks Pete

  Hi guys. i want to give a file(already present on the client computer .exe) permissions to always execute with administrative permissions. please note that the file i wants to give permissions is already on target machine. and i want to change permissions of that file through another program written in c# and it has administrative permissions to do everything. kindly let me know how to do it i am using this code System.Security.AccessControl.FileSecurity fs = File.GetAccessControl(@"c:\inam.exe"); FileSystemAccessRule fsar = new FileSystemAccessRule("Everyone", FileSystemRights.FullControl, AccessControlType.Allow); fs.AddAccessRule(fsar); File.SetAccessControl(@"c:\inam.exe", fs); this code will change the permissions correctly but still when i execute inam.exe after executing this code the UAC not appeared and also the inam.exe cant perform administrative operations. actually i have already deployed an application on more than 10,000 clients so wants to release a patch to resolve the administrative rights issue.

• How to prevent Closure Compiler from renaming "true", "false" and "null"

  - by Armagan Amcalar

  Google Closure Compiler renames all "true", "false" and "null" occurences in code like; var s = true, x = null, V = false; and uses these shorthands instead; in conditions such as; if (someVariable == s) now; Google Analytics code defines it's own "s" variable; overriding the value "true"; and as you can see this causes a lot of problems. I don't want to change GA code; I just want Closure Compiler to quit renaming true etc. Externs do not work. Do you know any way to accomplish this?

• Why Read In UTF-16LE File Won't Convert "\r\n" Into "\n" In Windows

  - by Dbger

  I am using Perl to read UTF-16LE files in Windows 7. If I read in an ascii file with following code: open CUR_FILE, "<", $asciiFile; Then each "\r\n" in file will be converted into a "\n" in memory; if I read in an UTF-16LE(windows 1200) file with following code: open CUR_FILE, "<:encoding(UTF-16LE)", $utf16leFile; Then "\r\n" will keep unchanged. This inconsistency cause problems when I trying to regexp lines with line breaks. My questions is: Is this how unicode works in Perl & Windows? Or Am I using the wrong code? Thanks so much!

• Am I immoral for using a variable name that differs from its type only by case?

  - by Jason Baker

  For instance, take this piece of code: var person = new Person(); or for you Pythonistas: person = Person() I'm told constantly how bad this is, but have yet to see an example of the immorality of these two lines of code. To me, person is a Person and trying to give it another name is a waste of time. I suppose in the days before syntax highlighting, this would have been a big deal. But these days, it's pretty easy to tell a type name apart from a variable name. Heck, it's even easy to see the difference here on SO. Or is there something I'm missing? If so, it would be helpful if you could provide an example of code that causes problems.

• Consuming RSS Feed In PHP

  - by mrduclaw

  I'm trying to use an RSS feed from my blog on the news section on another site. Everything seems to be working fine until I use something like an ellipsis on my blog. The expected output is: One more time…less fail Although this is no joking matter… The actual output is: One more time?less fail Although this is no joking matter… The problem is that ? should be a .... The code I'm using is the same for the first line (the blog title) and the second line (the blog contents) and that code is: $a = utf8_decode($a); print("$a"); Where $a is the string from the RSS feed. Can anyone point in the right direction why that code would work correctly for the body (second line) and not for the title (first line)? Or suggest a better way to do this? Thanks!

• Error processing response in .net web service with WSE3 mutualCertificate10Security Assertion

  - by Maeloc

  I am securing a .net web service (framework 2.0) with WSE3 mutualCertificate10Security Assertion. When request are valid all is fine and the response is wellformed, but when the request is invalid (cause a invalid signature, failed check, or soapexception thrown), the web server isn't able to process the response to send to the client. The error in application event log is: An error occured processing an outgoing fault response. Details of the error causing the processing failure: System.InvalidOperationException: Send security filter on the server could not retrieve the operation protection requirements from the operation state. en Microsoft.Web.Services3.Security.SecureConversationServiceSendSecurityFilter.SecureMessage(SoapEnvelope envelope, Security security) en Microsoft.Web.Services3.Security.SendSecurityFilter.ProcessMessage(SoapEnvelope envelope) en Microsoft.Web.Services3.Pipeline.ProcessOutputMessage(SoapEnvelope envelope) en Microsoft.Web.Services3.WseProtocol.GetFilteredResponseEnvelope(SoapEnvelope outputEnvelope) All certificate permissions are OK (when request is OK the web service is able to sign the response).
