  • Where do you find images and graphics for your softwares ?

    - by ereOn
    Hi, As a programmer, I'm sure some of you already experienced the same problem: You create a good software (free, open-source, or for friend-only diffusion, whatever) relying on good code and good ideas but since you're a programmer and not an image designer, your program looks just bad. While it seems pretty easy to find motivated developpers to join for free an open-source project, it seems quite hard to find a single free graphic designer. What free and good resources do you usually use for your programs/websites ? Do you have any cool tip that you're willing to share ?

  • Python: UTF-8 problems (again...)

    - by blahblah
    I have a database which is synchronized against an external web source twice a day. This web source contains a bunch of entries, which have names and some extra information about these names. Some of these names are silly and I want to rename them when inserting them into my own database. To rename these silly names, I have a standard dictionary as such: RENAME_TABLE = { "Wsird" : "Weird", ... } As you can see, this is where UTF-8 comes into play. This is the function which performs renaming of all the problematic entries: def rename_all_entries(): all_keys = RENAME_TABLE.keys() entries = Entry.objects.filter(name__in=all_keys) for entry in entries: entry.name = RENAME_TABLE[entry.name] entry.save() So it tries to find the old name in RENAME_TABLE and renames the entry if found. However, I get a KeyError exception when using RENAME_TABLE[entry.name]. Now I'm lost, what do I do? I have... # -*- coding: utf-8 -*- ...in the top of the Python file.

    - by Jon P
    I have a page, lets call it SourceTypes.aspx, that has a a GridView that is displaying a list of Source Types. Part of the GridView is a DataKey, SourceTypeID. If source TypeID is passed to the page via a query sting, how to I put the Gridview into Edit mode for the appropriate row based on the SourceTypeID? The GridView is bound to a SQlDataSource object. I have a feeling I am going to kick myself when the answer appears!! I have looked at Putting a gridview row in edit mode programmatically but it is some what lacking in specifics

  • WPF: Set style on immediate children only

    - by ollifant
    In my application I have a tab control which has several tab items. The problem is that I want to apply a style to these tab items, but to no other (nested) tab items. I have tried setting the following style on the tab control, but this also effects all children: <Style x:Key="tabControlStyle" TargetType="{x:Type TabControl}"> <Setter Property="TabItem.Template" Value="{StaticResource tabItemTemplate}" /> </Style> By using the code above I get the following error: 'TabItem' ControlTemplate TargetType does not match templated type 'TabControl', as TabItem and TabControl have the same DependencyProperty "Template", and the code tries to set the TabItemTemplate as TabControl- Template. Can anybody help me?

  • How to use multiple restrictions in C# Generics properly?

    - by plouh
    I am attempting to bind c# generics to a class and an interface like this: public class WizardPage<T> where T : UserControl, IWizardControl { private T page; public WizardPage( T page ) { this.page = page; } } And use it with this: public MyControl : UserControl, IWizardControl { //... } Somehow C# doesn't seem to be able to decide that MyControl is a proper instance of T as public class Wizard<T> where T : UserControl, IWizardControl { private WizardPage<T> Page1; public Wizard( MyControl control ) { this.Page1 = new WizardPage(control); } } fails with error The best overloaded method match for 'Controls.WizardPage.WizardPage(T)' has some invalid arguments Am I doing something wrong or is this just not going to work?

  • Smallest Java Runtime I can legally distribute?

    - by Mark
    My Java SWT desktop application is distributed with it's own Java runtime and I want to make the download size as small as possible. I'd like to remove all the classes I don't use from rt.jar, but this is forbidden according to JDK runtime licence (see the README.html file in the root JDK folder). Since Java is open source, am I allowed to compile my own 'Java' runtime from source which doesn't have this distribution restriction? If so, has anyone done this already? (Or do you just ignore the JDK licence terms?)

  • QuickTime movie disappearing from Javascript when scrolled offscreen in Firefox?

    - by c-had
    I have a web page I'm creating that uses Javascript to control an embedded QuickTime player. I add the QuickTime movie to the page using the AC_QuickTime.js file from Apple (as described here - http://developer.apple.com/mac/library/documentation/QuickTime/Conceptual/QTScripting_HTML/QTScripting_HTML_Document/ScriptingHTML.html#//apple_ref/doc/uid/TP40001525-2-SW1 ). Everything seems to be working fine - I can call methods on the QuickTime movie and control its playback (as well as get the current timestamp). The problem is that in Firefox, when I scroll down such that the QuickTime player is no longer visible, I get the following error every time I try to call a method on the QuickTime movie: Error calling method on NPObject! This does not occur in Safari. Why is this happening, and is there any way to work around this?

  • Handling dynamic number of columns

    - by Whistle
    I'm developing a CMS of sorts, and I want to give my users the possibility of customizing the display. More precisely, I want to give them the ability to choose to display or hide the left column, the right column and/or the top div. The middle column cannot be hidden since this is where the actual content will show, whereas the other columns are for navigation or side menus. I've been looking for a way to make this as smart and flexible as possible. For now I'm using a MasterPage, but that seems to be too constraining. For instance, with MasterPage you need to add a ContentPlaceHolder control in every of your ASPX pages. What are the best practices in this area? I guess a simpler way of saying this would be "I want to create a template system over which I have complete control".

  • VS2008 is very slow on a specific large C++ solution

    - by VioletRose
    I have a solution with 21 C++ projects and 1 VB.NET project. The IDE responds very slowly when I simply move the carret in a file or try to open the menu. The process seems to take 50% of CPU for each movement. It only happens with this solution and only on my machine. The solution has total of 2380 source and header files, of which 1280 are header files. I tried to remove all connection to the source control (Perforce) but it didn't help. Also, I have Visual Assist installed but even after removing it (uninstall), the same behavior continued. Any idea?

  • How can I figure out where all these extra sqlite3 selects are being generated in my rails app?

    - by radixhound
    I'm trying to figure out where a whole pile of extra queries are being generated by my rails app. I need some ideas on how to tackle it. Or, if someone can give me some hints, I'd be grateful. I get these: SQL (1.0ms) SELECT name FROM sqlite_master WHERE type = 'table' AND NOT name = 'sqlite_sequence' SQL (0.8ms) SELECT name FROM sqlite_master WHERE type = 'table' AND NOT name = 'sqlite_sequence' SQL (0.8ms) SELECT name FROM sqlite_master WHERE type = 'table' AND NOT name = 'sqlite_sequence' repeated over and over on every request to the DB (as much as 70 times for a single request) I tried installing a plugin that traced the source of the queries, but it really didn't help at all. I'm using the hobofields gem, dunno if that is what's doing it but I'm somewhat wedded to it at the moment Any tips on hunting down the source of these extra queries?

  • C# How to Identify Caller for Template Events

    - by mikeknoop
    I have a ListBox container data bound and templatized as so: <ListBox x:Name="ListBox" ItemsSource="{Binding Source={StaticResource List}}" ItemTemplate="{StaticResource ListTemplate}"> </ListBox> Within my ListTemplate resource, I define a Grid which contains a few child elements. I have setup a click event handler on one of child elements. The event hander is not row-specific, and I need a (best practice) way of identifying which row in the ListBox the event fired upon. From my data source, I have an unique ID which corresponds to the row. I do not currently expose this ID in the data binding, though could. Ideally I would like the event handler to be able to identify the ID of the row the event was fired upon. Thank you!

  • Why is the page still caching even after the no-cache headers have been sent?

    - by Matthew Grasinger
    I've done a ton of research on this and have asked many people with help and still no success. Here are the details... I'm involved in developing a website that pulls data from various data files, combines them in a temp .csv file, and then is graphed using a popular graphing library: dygraphs. The bulk of the website is written in PHP. The parameters that determine the data that is graphed are stored in the users session, the .csv is named after the users session and available for download, and then the .csv file is written in a script that passes it to the dygraphs object. And we've found, even with the no-cache headers sent: header("Cache-Control: no-cache, must-revalidate"); header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); Many users experience in the middle of a session, (if enough different graphs are generated) the page displaying an older, static rendering of the page (data they had graphed earlier in the session) as if it were cached and loaded instead of getting a new request. It only gets weirder though: I've checked using developer tools in both Firefox and Chrome and both browsers are receiving the no-cache headers just fine; Even when the problem occurs if you view the page source, the source is the correct content (a table/legend is also dynamically created using php, the source shows the correct table, but what is rendered is older content); the page begins to render correctly until the graph is about to be display, and then shows the older content; the older content displays as if it were a completely static overlay--the cached graph does not have the same dynamic features (roll over data point display, zoom and pan, etc.) And it is as if the correct page were somewhere beneath it (the download button for the csv file moves depending on how large the table is. The older, static page does nothing if you click the download .csv button, but if you can manage to find the one in the page beneath it you can click and still download the .csv. The data in the .csv is correct) It is one of the strangest things I've seen in development thus far. Some other relevant facts are that all the problems I've personally experience occurred while I was using Chrome. Non of these symptoms have been reported by Firefox users. IE users have had the same problems (IE users are forced to use chrome frame). I'm at my wits end at this point. We've sent the php headers; we've tried setting the cache profile for php on IIS as "DisableCache" (or whatever); we've tried sending a random query string to the results page; we've tried all the appropriate meta tags--all with no success.

  • How to choose programaticaly the column to be queried by Linq using PropertyInfo???

    - by Richard77
    Hello, I would like to control how linq querries my database programaticaly. For instance, I'd like to query the column X, column Y, or column Z, depending on some conditions. First of all, I've created an array of all the properties inside my class called myPropertyInfo. Type MyType = (typeOf(MyClass)); PropertyInfo[] myPropertyInfo = myType.GetProperties( BindingFlags.Public|BindingFlags.Instance); The myPropertyInfo array allows me to access each property details (Name, propertyType, etc) through the index*[i]* Now, how can I use the above information to control how linq queries my DB? Here's a sample of a querry I'd like to exploit. var myVar = from tp in db.MyClass select tp.{expression}; Expression using myPropertyInfo[i] to choose which property(column) to query. I'm not sure if that's the way of doing it, but if there's another way to do so, I'll be glad to learn. Thanks for helping.

  • SSIS - user variable used in derived column transform is not available - in some cases

    - by soo
    Unfortunately I don't have a repro for my issue, but I thought I would try to describe it in case it sounds familiar to someone... I am using SSIS 2005, SP2. My package has a package-scope user variable - let's call it user_var first step in the control flow is an Execute SQL task which runs a stored procedure. All that SP does is insert a record in a SQL table (with an identity column) and then go back and get the max ID value. The Execute SQL task saves this output into user_var the control flow then has a Data Flow Task - it goes and gets some source data, has a derived column which sets a column called run_id to user_var - and saves the data to a SQL destination In most cases (this template is used for many packages, running every day) this all works great. All of the destination records created get set with a correct run_id. However, in some cases, there is a set of the destination data that does not get run_id equal to user_var, but instead gets a value of 0 (0 is the default value for user_var). I have 2 instances where this has happened, but I can't make it happen. In both cases, it was just less that 10,000 records that have run_id = 0. Since SSIS writes data out in 10,000 record blocks, this really makes me think that, for the first set of data written out, user_var was not yet set. Then, after that first block, for the rest of the data, run_id is set to a correct value. But control passed on to my data flow from the Execute SQL task - it would have seemed reasonable to me that it wouldn't go on until the SP has completed and user_var is set. Maybe it just runs the SP, but doesn't wait for it to complete? In both cases where this has happened there seemed to be a few packages hitting the table to get a new user_var at about the same time. And in both cases lots of data was written (40 million rows, 60 million rows) - my thinking is that that means the writes were happening for a while. Sorry to be both long-winded AND vague. A winning combination! Does this sound familiar to anyone? Thanks.

  • ASP.Net aspx markup

    - by Batuta
    I am working on some old web forms application. When I changed from design to view source of the aspx page, the aspx markup becomes disarranged. For example, a label is written as follows: <asp:label id="Label20" style="Z-INDEX: 119; LEFT: 16px; POSITION: absolute; TOP: 424px" runat="server" Height="24px" Width="72px">Instructions:</asp:label> It suddenly becomes like this (when I toggle from design to source) <asp:label id="Label20" style="Z-INDEX: 119; LEFT: 16px; POSITION: absolute; TOP: 424px" runat="server" Height="24px" Width="72px">Instructions:</asp:label> Notice that the alignment and margins, tab stops are changed. Any idea how to prevent VS from doing this? Thanks.

  • How do I setup Eclipse to stop on the line an exception occured?

    - by Chris Persichetti
    Hi, How can I setup Eclipse to stop at the point an exception occurred. I have an Eclipse breakpoint setup to break on an exception. In the code example below, the problem I'm having is Eclipse tries to open the Integer source code. Is there any way to just have debugger break at the point shown in my code example? If I move down the stack trace, I will get to this line, it'd be nice if there's a way to do this without the "Source not found" window coming up. This can be done in Visual Studio, so it's driving me crazy not being able to find a way to do this in Eclipse. package com.test; public class QuickTest { public static void main(String[] args) { try { test(); } catch(NumberFormatException e) { System.out.println(e.getMessage()); } } private static void test() { String str = "notAnumber"; Integer.parseInt(str);//<----I want debugger to stop here } }

  • Query MS Access database in VB 2008

    - by Logan
    Hi, I added an Access database as a Data Source in VB 2008. I want to query this database and use the information in various ways throughout the program. For example, there is an Employee table with first/last names of employees. I have a combobox on my form that I want to display all of the employees. So I want to query the database for all the rows in the Employee table, and add them to the combobox as I go. I am familiar with SQL Syntax, so I am not asking how to write the query itself, but rather how to fetch rows in VB code (mimicking php's mysql_fetch_assoc and mysql_connect essentially) Thanks! Edit: Also, I want to know if I can query a DB if I don't add it as a data source (if I know the path name of the database)
