• Build turns partially transparent image pixels black

  - by Sean O'Hollaren

  I'm very new to C# and I've run into a problem and haven't been able to solve it. I have a row of buttons that have .png images assigned to them. The images are in .png format to allow transparency, and smoothing the edges in GIMP leaves some semi-transparent pixels. I've set the Image List Toolbar (imglToolbar)'s properties to recognize "Transparent" as the designated color to show up as transparent. I'm working in Visual Studio 2005. The strange thing is that everything looks great when I'm viewing the Visual C# form preview window. The icons look exactly as they should. However, once I actually build the project, the buttons treat every semi-transparent pixel near the edge of the image as if it's black. It seems like it can't handle one that's both transparent and has color. Image of it via the Visual C# form editor: Image of what it looks like when built: Any ideas as to why this is happening?

• display image on a report based on two date

  - by Yongwei Xing

  Hi all I am using sql server 2005 reporting service to generate report base on a database. There are two columns which are datetime type ColumnA and ColumnB. The report would display a KPI image on this report by comparing these two columns.Below is the expression for selecting image SWITCH(DateDiff("d",Fields!ColumnA.Value,Fields!ColumnB.Value)<0,"kpi_r", DateDiff("d",Fields!ColumnA.Value,Fields!ColumnB.Value)>0,"kpi_g", DateDiff("d",Fields!ColumnA.Value,Fields!ColumnB.Value)=0,"kpi_y") For most of the records, the image is correct. Only for one record, the result is very strange. For this record ColumnA=2010-04-23 08:00:00 ColumnB=2010-04-22 17:00:00 It would display kpi_r, it displayed kpi_y. I have checked the value of DateDiff(d,Fields!ColumnA.Value,Fields!ColumnB.Value) in the SSMS, the value is -1. Why does it display kpi_y? Does anyone meet this problem before? Best Regards,

• C# Bug or Brain Teaser? Cast working only with Coalesce (??) Operator

  - by Alex

  This is very strange, maybe someone can explain what's happening, or this is a bug (though I tend to think that this is probably just something intricate about C#). The following code throws the error "Cannot implicitly convert type 'uint?' to 'uint'.": public void Test(UInt32? p) { UInt32 x = p; } However, this code works without error: public void Test(UInt32? p) { UInt32 x = p ?? 1; } Huh? Why does this work? Why would the coalesce operator cause implicit conversion of UInt32? (nullable) to UInt32 (non-nullable), while the first error message says that there is no implicit conversion between those types?

• ASP.Net mysterious behaviour

  - by kalan

  Does anyone have any idea why this works (expression in the if-clause) if (!(childNode.Roles != null && !Helper.HasEqualElements((string[])childNode.Roles, System.Web.Security.Roles.GetRolesForUser()))) AddNode(childNode, parentNode); And this doesn't if (childNode.Roles == null || Helper.HasEqualElements((string[])childNode.Roles, System.Web.Security.Roles.GetRolesForUser())) AddNode(childNode, parentNode); The problem is that the second if-clause sometimes doesn't work. Though it always works in debug mode, but it sometimes fails while running. And the strange thing is that these two pieces of code seems absolutely equal for me.

• android dialog transparant

  - by Doomic

  It is a simple stupid question, but i cant find any info on the web. I have an android app with a custom dialog. The dialog has the default grey 1px border. But it also has a black border around that grey line. I want to remove the black part. the dialog is made in xml and i call: dialog.setContentView(R.layout.xxxxx); as soon as i do that the black border is there. However the xml has not a background color set. also a transparant color in the xml doesn't helps. if i do not call setcontentview. then a small dialog appears but without a strange border.

• Django-admin.py not being recognized suddenly

  - by Jen Camara

  I tried starting a new Django project yesterday but when I did "django-admin.py startproject projectname" I got an error stating: "django-admin.py is not recognized as an internal or external command." The strange thing is, when I first installed Django, I made a few projects and everything worked fine. But now after going back a few months later it has suddenly stopped working. I've tried looking around for an answer and all I could find is that this typically has to do with the system path settings, however, I know that I have the proper paths set up so I don't understand what's happening. Does anybody have any idea what's going on?

• Rails 3 render :partials

  - by user297221

  Hi guys. I am migrating my 1.8.7 rails app to rails 3. But I have a problem with a partial: I have the following partial: in my cms controller : @clients = Client.all group = render_to_string :layout = 'layouts/window', :partial = 'clients/index' in my "clients/index" partial: <%= render :partial = 'clients/item', :collection = @clients % This worked great with rails 1.7.8 but with rails 3 only the partial in the index get's rendered!. So, to clarify this, the group variable in the controller doesn't get the html from the layout. Also the weird thing is that the window layout is _window.erb (if I do window.html.erb or just window.erb rails can't find it which is strange). Does anybody know if this behavior is normal for rails 3? thanxs!

• Problems with Ruby "||" "or"?

  - by Kevin

  Beginning Ruby Question: I'm trying to see if a string variable's contents is either "personal" "email" or "password". I'm trying: if params[:action] == "password" || "email" || "personal" foo else don't foo end But that doesn't work and returns strange results, and using IRB to play around with "or" statements I have no idea why the following happens: irb(main):040:0> a = "email" => "email" irb(main):041:0> a == "password" || "email" => "email" irb(main):042:0> a == "email" || "password" => true I just want something that if any of the 3 variables are true no matter what order they are in it returns true, if not it returns false. Anyone want to help this n00b out?

• Map Reduce job on Amazon: argument for custom jar

  - by zero51

  Hi all, This is one of my first try with Map Reduce on AWS in its Management Console. Hi have uploaded on AWS S3 my runnable jar developed on Hadoop 0.18, and it works on my local machine. As described on documentation, I have passed the S3 paths for input and output as argument of the jar: all right, but the problem is the third argument that is another path (as string) to a file that I need to load while the job is in execution. That file resides on S3 bucket too, but it seems that my jar doesn't recognize the path and I got a FileNotFound Exception while it tries to load it. That is strange because this is a path exactly like the other two... Anyone have any idea? Thank you Luca

• How can I consume A web-service reference like a dll

  - by Sergiu

  I have a small question: Can we consume a web-service reference like a sample dll? I mean something like following: 1. Add reference to assembly in the references 2. add namespace to using (using mywebservice) 3. use it in code like: var service = new mywebservice.Service1(); var result = service.GetSomething()? Why I'm asking? It's because of I tried but I get a "strange" error: Cannot load assembly "MyService.dll version, and so on". Thanks in advance!

• bash find xargs grep only single occurence

  - by keftebub

  hi. maybe it's a bit strange - and maybe there are other tools to do this but, well.. i am using the following classic bash command to find all files which contain some string: find . -type f | xargs grep "something" i have a great number of files, on multiple depths. first occurence of "something" is enough for me, but find continues searching, and takes a long time to complete the rest of the files. what i would like to do is something like a "feedback" from grep back to find so that find could stop searching for more files. is such a thing possible? thank you

• sqrt(int_value + 0.0) ? The point?

  - by Earlz

  Hello, while doing some homework in my very strange C++ book, which I've been told before to throw away, had a very peculiar code segment. I know homework stuff always throws in extra "mystery" to try to confuse you like indenting 2 lines after a single-statement for-loop. But this one I'm confused on because it seems to serve some real-purpose. basically it is like this: int counter=10; ... if(pow(floor(sqrt(counter+0.0)),2) == counter) ... I'm interested in this part especially: sqrt(counter+0.0) Is there some purpose to the +0.0? Is this the poormans way of doing a static cast to a double? Does this avoid some compiler warning on some compiler I do not use? The entire program printed the exact same thing and compiled without warnings on g++ whenever I left out the +0.0 part. Maybe I'm not using a weird enough compiler?

• Using jQuery in WordPress plugin admin page?

  - by Volmar

  I have a strange problem that probably have a really simple explanation that i've just havn't found. I'm making a WordPress plugin and i want to use jQuery in my settings-page for the plugin. My JS functions look like this: jQuery(document).ready(function() { alert('load test'); //ADMIN FUNCTION $('#mrc_imp_img').click(function(){ alert("test"); }); //FRONT END FUNCTION $("ul.mrc li").hover(function() { $(this).find('p').fadeIn(); } , function() { $(this).find('p').fadeOut(); }); }); The "load test"-alert is being loaded when the document is ready so jquery is properly loaded. The front end function is being used on pages and that's working fine to. the problem is the admin function, it's not working at all. is there a speial way i have to write a .click()-function to get it to work on my settings-page for the wordpress plugin?

If anyone can help me out I would be extremely grateful!

• How to break whenever any line of code executes

  - by Aequitarum Custos

  I have a very strange bug, which I believe is caused by some code we have executing, but I'm not sure where. We can reproduce it to the point it happens whenever we click Tab, but short of putting a break point at the beginning of every method in the project to find out what is executing. Is there a way to set visual studio to break whenever anything executes? For those curious about the problem, every now and then, we have a few Rich Text Boxes that refuse to lose focus. You can't click out of it or tab out of it. We have no On Validation or On Text Changed events attached to the control, and believe it's an event attached somewhere else to something we just aren't noticing.

• Rendering inconsistencies in Internet Explorer

  - by gmunk

  Hello, I have some weird problem in rendering some xhtml in IE 8 http://img709.imageshack.us/i/scrj.png/. Here is the screenshot. As shown the greet me submit button is higher than the text field. Which is kind of odd. I checked with some other browsers and it works fine, it also works fine on Windows 7 with IE 8. Here is the code for the site: http://pastebin.com/cUkVA1HP http://pastebin.com/nU4cdpDE and the reset I'm using http://pastebin.com/uyEbAsEF I'm really puzzled by this strange behaviour. Thanks in advance for any ideas.

• ODBC Storage Size

  - by dcp3450

  I'm pulling a lot of text from a MS SQL Server database. I'm not getting all the text (which includes some html. The text is stored perfectly on the database. However, when I run the query to get the data It will only pull part of the text. I pull the data using odbc_exec and store using $variable = odbc_result($runquery,"body"). if i display the content with odbc_result_all($runquery) i get part of the content. if I use echo $body; i get part of the content then some garbage and part of the text from the begining. very strange response. Is there a size limit? Any ideas what I'm missing here?

• WebGL transparent black.

  - by Catalin Dumitru

  I have a strange problem that I can't figure out when trying to do blending in WebGL. Black is rendered fully transparent , and everything with shades of grey in it is rendered also semi transparent. I have set it to use the alpha channel as the source for transparency, and in some respect it works, every thing that isn't black/grey is rendered differently when changing the alpha value. but even when I set the alpha to 1, black is still displayed transparent. This is how I enable transparency: this.gl.blendFunc(this.gl.SRC_ALPHA, this.gl.ONE); this.gl.enable(this.gl.BLEND); this.gl.disable(this.gl.DEPTH_TEST); And the part of the shader that does transparency: gl_FragColor = vec4(texColor.rgb * vLightWeight, texColor.a * uAlpha); where texColor is the texture color that is being sampled, vLightWeight is the shadowing that is being calculated in the vertex shader, and uAlpha the uniform which I use for transparency.

• Why does internet explorer 8 fail to locate jpg files that other browsers can find?

  - by user278457

  The following URL doesn't display for me in Internet Explorer 8. I even tried compatibility mode and it didn't fix the issue. http://beat.com.au/sites/default/files/images/_DSC5596.jpg It appears just fine in Chrome/Safari/Firefox. I suspect it has something to do with the filename starting with _ but that seems like a fairly big stretch to me. Is this error repeatable on other people's computers? And why on earth would such a strange thing happen anyway?

• Arguments to convince to switch from CVS to SVN

  - by ereOn

  Hi, The UNIX department of my company currently uses CVS as source-version control system. They use it in a very strange way: different repositories for development/testing/production code (for the same project), no one tags anything, weird directory architecture, and so on. The system has been set for ages but now, I have an opportunity to organize a meeting where I have to suggest changes. I'd like to make them change from CVS to SVN (Mercurial or Git might be even better, however I can't really recommand using a system I don't know well, and switching to SVN will already be a great step forward). I don't have much experience with CVS so I can't compare them efficiently: I just know it doesn't support atomic operations and that it is deprecated. What killer arguments would you use to convince my collegues to do the switch ? Thank you very much.

• JSF Rendering Issue (Page getting cached)

  - by Shamik

  I am facing a strange issue with JSF. I have developed one controller and bind it to request scope. I need to access one jsf page like http://localhost:8080/selectRule.jsf?type=A and on the same IE session I want to issue another request like http://localhost:8080/selectRule.jsf?type=B as we can see, only the type is changing here. This is why I have a ruleController bound to request scope, so that every request, creates the controller and pulls out the data depending upon type. I have a private HtmlSelectOneMenu choices item in the page. What I see is, somehow only once in the session the getChoices() is getting called. This is what I see For each url, one new ruleController object is getting created. Only first time getChoices() are called. In the subsequent time, if I change the URL in the web browser, the getChoices() method are not getting called though a new controller is getting created. Note: I am using JSF 1.1

• varchar data type to datetime data type resulted in an out-of-range??

  - by leen3o

  Very weird problem occurred, I have moved a site from one server to another - All is working, but any query involving a date is playing up. I get the following: DELETE FROM MYTABLE WHERE categoryId = -2 AND datecreated < '3/23/2010'; The conversion of a varchar data type to a datetime data type resulted in an out-of-range value Now what's strange is I have changed the LCID to 1033 on the new server as the date is showing as US format and its still throwing an error! I then tried 2057 and again the same error? Made no difference. I'm a little confused, as this is a working site from a server with IIS6 - The locale is 1033 on that server and it works perfectly!! :S I have just tried thrown a Cdate() around the date too and yet again the same error??? Any ideas??

• SVN Export in Eclipse removes labels on tabs

  - by Sorcy

  I have a very strange effect when using subclipse with eclipse. Whenever I use Team-Export to export a file from the editor the export works fine, but the label of the tab of the file is removed. Effect can be seen here: http://www.daspferd.de/img/tabs.png Strangely enough it happens with php-files, css-files, html-files but NOT with javascript-files. So I'm assuming it's some kind of setting that I haven't found yet and not a bug in subclipse. Anyone know where I can shut down this behaviour?
