  • Rank Source Control Options-VSS vs CVS vs none vs your own hell

    - by Roman A. Taycher
    It seems like a lot of people here and on many programmer wikis/blogs/ect. elsewhere really dislike VSS. A lot of people also have a serious dislike for cvs. In many places I have heard a lot of differing opinions on whether or not using VSS or cvs is better or worse then using no source control, please rate the worst and explain why!!!!! you rated them this way. Feel free to throw in your own horrible system in the rankings. If you feel it depends on the circumstances try to explain the some of the different scenarios which lead to different rankings. (note:I see a lot of discussion of what is better but little of what is worse.) second note: while both answers are nice I'm looking less for good replacements and more for a comparison of which is worse and more importantly why!

  • Authlogic Multiple Password Validation

    - by Hock
    Hello, I'm using Authlogic to manage my user sessions. I'm using the LDAP add-on, so I have the following in my users model acts_as_authentic do |c| c.validate_password_field = false end The problem is that recently I found out that there will be some users inside the application that won't be part of the LDAP (and can't be added!). So I would need to validate SOME passwords against the database and the others against the LDAP. The users whose password will be validated against the database will have an specific attribute that will tell me that that password will be validated in my database. How can I manage that? Is it possible that the validate_password_field receives a "variable"? That way I could create some method that will return true/false depending on where the password validation will be done? Thanks!

  • Turn Non-Resizeable Windows into Rezieable Windows

    - by Asian Angel
    Are you frustrated with Windows app windows that can not be resized at all? Now you can apply some “attitude adjustment” and resize those windows with ResizeEnable. Before Everyone is familiar with the many app windows in their Windows OS that simply can not be resized. What you need is cooperation, not attitude. For our example we chose the “Taskbar and Start Menu Properties Window”…notice the cursor in the lower right corner. No resizing satisfaction available at all… After The program comes in a zip file with three files as shown here. Once you have unzipped the program place it in an appropriate “Program Files Folder”, create a shortcut, and you are ready to go. There will be a “System Tray Icon” with only two “Context Menu” items…“About & Quit”. Here is a quick look at the “About Window” that tells you exactly what ResizeEnable does. Notice that it does state that you may occasionally have a window that may not respond correctly. Now back to our “Taskbar and Start Menu Properties Window”. Notice the resizing cursor in the lower right corner….time for some fun! During our test the “Taskbar and Start Menu Properties Window” was suddenly a dream to resize. Daring to stretch the window even further…now that is what you call “stretching” the window out in comparison to its’ original size! Think of all the windows that will be much easier to work with now… Conclusion If you have been frustrated with non-resizeable windows then ResizeEnable will certainly bring a smile to your face as you watch those windows suddenly become a lot more cooperative. This is definitely one app that is worth adding to your system.

  • After adding a UILabel to my view, how do I delete it?

    - by Travis
    I have added a UILabel to my view programmatically like this: myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 100.0f, 30.0f)]; myLabel.center = CGPointMake(160.0f, 120.0f); myLabel.backgroundColor = [UIColor clearColor]; myLabel.textColor = [UIColor whiteColor]; myLabel.font = [UIFont fontWithName:@"Helvetica" size: 18.0]; myLabel.textAlignment = UITextAlignmentCenter; myLabel.text = @"Hello"; [self.myView addSubview:myLabel]; To add a label to my view. What I can't seem to find out is once I'm done w/ the label (at a future point) how can I delete it from the view? [myLabel release] doesn't seem to work which I think makes sense because the view it's added to probably retained it's over reference. So what is the best practice?

  • Do we need to disconnect from sharepoint? If Yes How? ( using Web Services : C#)

    - by Pari
    Hi, I am using web services to access sharepoint list,sites and documents. Like: List.asmx,Site.asmx e.t.c. My question is that: Do we need to disconnect from sharepoint when using above services? And if yes then How? Example: GetSiteCollection(String login, String password, String url) { Webs ws = new Webs(); try { ws.Credentials = new NetworkCredential(login, password); } catch (Exception ex) { MessageBox.Show(ex.Message); } ws.Url = url + @"/_vti_bin/webs.asmx"; ws.PreAuthenticate = true; XmlNode websiteNode = ws.GetWebCollection(); XmlNodeList nodes = websiteNode.SelectNodes("*"); // getting list set of sites //Now here after this is there any way to disconnect from server? }

  • Android Tile Bitmap

    - by Rich Lawrence
    I'm trying to load a bitmap in Android which I want to tile. I'm currently using the following in my view to display a bitmap: canvas.drawBitmap(bitmap, srcRect, destRect, null) I essentially want to use this bitmap as a background image in my app and would like to repeat the bitmap in both the X and Y directions. I've seen the TileMode.REPEAT constant for the BitmapShader class but am unsure if this is to do with repeating he actual bitmap or to do with applying a filter to the bitmap.

  • App engine datastore - query on Enum fields.

    - by Gopi
    I am using GAE(Java) with JDO for persistence. I have an entity with a Enum field which is marked as @Persistent and gets saved correctly into the datastore (As observed from the Datastore viewer in Development Console). But when I query these entities putting a filter based on the Enum value, it is always returning me all the entities whatever value I specify for the enum field. I know GAE java supports enums being persisted just like basic datatypes. But does it also allow retrieving/querying based on them? Google search could not point me to any such example code. Details: I have printed the Query just before being executed. So in two cases the query looks like - SELECT FROM com.xxx.yyy.User WHERE role == super ORDER BY key desc RANGE 0,50 SELECT FROM com.xxx.yyy.User WHERE role == admin ORDER BY key desc RANGE 0,50 Both above queries return me all the User entities from datastore in spite of datastore viewer showing some Users are of type 'admin' and some are of type 'super'.

  • Is it possible to build a WinForm app (or another type of .NET app) which allows me to interact with

    - by RoboShop
    I'm learning Chinese at the moment and I have gotten my hand on a Chinese dictionary definition. Now I would like to make an interface. All I really want the application to do is when I point my mouse pointer over any text on the screen (in any window), it would identify the text I am pointing at and then display a small form over it, which would the chinese transaction. Is that possible to do? Can WinForms apps interact with windows outside of it's own application?

  • What is a best free way to make form resizeable in Delphi 7?

    - by Tofig Hasanov
    I need my form in Delphi to be resizeable, and all components and controls should stretch proportionally, along with font sizes etc. Right now in order to resize components I write a code inside "OnResize" event, and manually calculate all components' sizes and fonts. I would like to have more simple solution, which I can apply to different applications without rewriting this code for each form. I found some components on the web, but they are shareware. Can you suggest something?
