  • table cell background color change problem

    - by Mellon
    I work on another guy's code, and I try to change the table cell background color when mouse over the cell, and change back to the original background color when mouse leave. I use the following code: var bgcolor=$(".cell-el").css("background-color") $(".cell-el").hover( function(){ $(this).css("background-color", "#3c3c36")}, //mouse enter, bg-color change function(){ $(this).css("background-color", bgcolor) // mouse leave, bg-color change back }) Things are working fine, EXCEPT that when mouse first time enter the cell, the cell background color is not changed to "#3c3c36", but when mouse leave the cell after first entering and enter in the cell again, the cell's background color changed to "#3c3c36". That's the cell color never change for mouse first enter, after that, everything is working great. What's could be the cause of this problem?

  • Service Application too visible

    - by Tom
    Working on a service application in Delphi 5 that is intended to run on Windows XP - 7. Most of the application is coming together nicely, but I'm running into one issue. Part of this service application is a form that displays data occasionally (similar to the slider box Avast uses to let you know its updated). When the service shows the form, the form displays on the taskbar, but we don't want it to. Does anyone have any suggestions as to how to hide the form's button on the taksbar? None of the standard methods I've found for regular applications have worked so far. Thanks.

  • Deployment of a .NET application making use of SQL Server 2008

    - by Victor John Saliba
    I have searched the internet thoroughly for this type of issue, there were responses but hasn't really found a concrete solution yet. I have an application which makes use of SQL Server 2008 R2 and thus it makes connections with a database file which I have set up. The application executes successfully, makes connections with the database and retrieves/inserts/updates data to and fro the database. However when I come to create a deployment project i.e. a setup project, I fail to transfer my database files to other computers and make database connections. I have checked the SQL Server 2008 prerequisite in the publish settings of the application and has also included the database files. Can anyone suggest the best way to this type of setup? Thanks

  • Reset application and settings on user change

    - by Don
    Currently working on a project where a login will be required to use the application. I'm trying to figure out a smarter way to reset the application if someone is somehow logged out and the next one to login is not the same user. The option I have come up with at the moment is storing all user specific data/information in a DTO but this leaves me with cleaning up some parts of the work area. Is a ResetControls my only option here? I'm afraid that when updating the application someone might forget to update that part, most likely myself now that wrote it out. Anybody with experience in this that could provide some ideas to a simple yet fairly automagic solution?

  • Why is my background image not displaying properly in IE7?

    - by JAG2007
    Screenshot of the issue: here Webpage in Question: http://cure.org Offending browser: Internet Explorer 7 You'll notice from the screenshot, or if you view this site in IE7, that the background image is not displaying for the content div (#modal-inner-content). Strangely, the image displays in the other divs where it is used (since it's a sprite, I'm using that same image for #modal-top-border and #modal-btm-border). In all other browsers it displays properly, and even in IE8. I cannot seem to find what CSS rule (or lack thereof) I may be using that IE7 is choking on. NOTE: in order to get the modal screen, just click the link at the very top banner of the page that says "login to your CURE account

  • Execute an external application as root - problem

    - by user598011
    Good morning: I'm trying to run an external application that needs to be executed as root. I have to read the lines from exit after the execution of this application but it says "permission denied", as if the its not been done correctly. I've been thinking over a time and I can not move forward. The code is as follows: process = Runtime.getRuntime().exec("su"); String[] command = {external application command}; process = Runtime.getRuntime().exec(comando); InputStream inputStream = process.getInputStream(); BufferedReader bufferedReader = null; try { bufferedReader = new BufferedReader(new InputStreamReader(inputStream),8192); String line = null; while ((line = bufferedReader.readLine()) != null) { System.out.println("read line:"+line ); } } catch (IOException ioe) { ioe.printStackTrace(); } process.waitFor(); Does anyone know why not let me run the command? Thanks.

  • What size should the background image in an MSI be?

    - by r_
    I am trying to create a Windows Installer package using Wix. I'm getting a lot of conflicting information about what size my custom background should be--the Wix documentation suggests a size of 500 x 314 pixels, but this leads to slight image distortion in the installer. I believe that I may be indirectly using the SplashBitmap property in Windows Installer, whose documentation suggests 480 x 320 is the correct size. When I try to use this image size, I also get artefacts in the image. Could anyone tell me what the correct size should be?

  • CSS- How to align background image over bottom border line? Jsfiddle included

    - by John Robinson
    I have an image I am trying to display over the top of a bottom border, but it is being arranged behind the bottom border element (in this example, named "divider"), and I can't get it to align correctly. I would like the image to be displayed in the middle of the the border element and over the top of it. Vertically, I am trying to get the 1px line on the left and right side of the image to align with the 1px border to appear as if it is one element. Here is the code: .divider { border-bottom: 1px solid #c3c3c3; clear: both; display: block; margin-bottom: 20px; padding-top: 20px; width: 100%; } .sidearrow { background: url(http://s16.postimage.org/sbf7v9n75/sidearrow.png) 50% 14px no-repeat; width: 100%; height: 25px; }? <p>Here is some content above</p> <div class="sidearrow"></div> <div class="divider"></div> <p>Here is some content below</p>? And the jsfiddle: http://jsfiddle.net/F5xjx/2/ Any ideas how to get this to work? Thanks in advance.

  • Are background threads a bad idea? Why?

    - by Matt Grande
    So I've been told what I'm doing here is wrong, but I'm not sure why. I have a webpage that imports a CSV file with document numbers to perform an expensive operation on. I've put the expensive operation into a background thread to prevent it from blocking the application. Here's what I have in a nutshell. protected void ButtonUpload_Click(object sender, EventArgs e) { if (FileUploadCSV.HasFile) { string fileText; using (var sr = new StreamReader(FileUploadCSV.FileContent)) { fileText = sr.ReadToEnd(); } var documentNumbers = fileText.Split(new[] {',', '\n', '\r'}, StringSplitOptions.RemoveEmptyEntries); ThreadStart threadStart = () => AnotherClass.ExpensiveOperation(documentNumbers); var thread = new Thread(threadStart) {IsBackground = true}; thread.Start(); } } (obviously with some error checking & messages for users thrown in) So my three-fold question is: a) Is this a bad idea? b) Why is this a bad idea? c) What would you do instead?

  • how to enable SQL Application Role via Entity Framework

    - by Ehsan Farahani
    I'm now developing big government application with entity framework. at first i have one problem about enable SQL application role. with ado.net I'm using below code: SqlCommand cmd = new SqlCommand("sys.sp_setapprole"); cmd.CommandType = CommandType.StoredProcedure; cmd.Connection = _sqlConn; SqlParameter paramAppRoleName = new SqlParameter(); paramAppRoleName.Direction = ParameterDirection.Input; paramAppRoleName.ParameterName = "@rolename"; paramAppRoleName.Value = "AppRole"; cmd.Parameters.Add(paramAppRoleName); SqlParameter paramAppRolePwd = new SqlParameter(); paramAppRolePwd.Direction = ParameterDirection.Input; paramAppRolePwd.ParameterName = "@password"; paramAppRolePwd.Value = "123456"; cmd.Parameters.Add(paramAppRolePwd); SqlParameter paramCreateCookie = new SqlParameter(); paramCreateCookie.Direction = ParameterDirection.Input; paramCreateCookie.ParameterName = "@fCreateCookie"; paramCreateCookie.DbType = DbType.Boolean; paramCreateCookie.Value = 1; cmd.Parameters.Add(paramCreateCookie); SqlParameter paramEncrypt = new SqlParameter(); paramEncrypt.Direction = ParameterDirection.Input; paramEncrypt.ParameterName = "@encrypt"; paramEncrypt.Value = "none"; cmd.Parameters.Add(paramEncrypt); SqlParameter paramEnableCookie = new SqlParameter(); paramEnableCookie.ParameterName = "@cookie"; paramEnableCookie.DbType = DbType.Binary; paramEnableCookie.Direction = ParameterDirection.Output; paramEnableCookie.Size = 1000; cmd.Parameters.Add(paramEnableCookie); try { cmd.ExecuteNonQuery(); SqlParameter outVal = cmd.Parameters["@cookie"]; // Store the enabled cookie so that approle can be disabled with the cookie. _appRoleEnableCookie = (byte[]) outVal.Value; } catch (Exception ex) { result = false; msg = "Could not execute enable approle proc." + Environment.NewLine + ex.Message; } But no matter how much I searched I could not find a way to implement on EF. Another question is: how to Add Application Role to Entity data model designer? I'm using the below code for execute parameter with EF: AEntities ar = new AEntities(); DbConnection con = ar.Connection; con.Open(); msg = ""; bool result = true; DbCommand cmd = con.CreateCommand(); cmd.CommandType = CommandType.StoredProcedure; cmd.Connection = con; var d = new DbParameter[]{ new SqlParameter{ ParameterName="@r", Value ="AppRole",Direction = ParameterDirection.Input} , new SqlParameter{ ParameterName="@p", Value ="123456",Direction = ParameterDirection.Input} }; string sql = "EXEC " + procName + " @rolename=@r,@password=@p"; var s = ar.ExecuteStoreCommand(sql, d); When run ExecuteStoreCommand this line return error: Application roles can only be activated at the ad hoc level.

  • Visual Studio Plug-in that can tell the Application Pool name of w3wp.exe when debugging

    - by Colin Niu
    Is there any plug-in for Visual Studio that can display the associated Application Pool name for those w3wp processes when debugging them with "Attach to Process..." ? Usually I have to do following steps before debugging: c: \Windows\system32\inetsrv\appcmd list wps then I get the process id for the Application Pool I want to debug, and then attach it in the Attach to Process window. I feel it will be very pleasure if there's a plug in can do this automatically, but didn't find any such thing after Googled.

  • One-Click Application Moving from WinForms to WPF

    - by Tyler
    I have a WinForms app that I recently re-wrote in WPF and I need to release to my end users. I'd like to be able to have the users go to the ClickOnce install point for the WPF application and have their WinForm application removed so they don't have both on their machine What's the best way (read: easiest for users) of accomplishing this? I have thought about creating an prereq command line app to detect the old version and uninstall, but would like to avoid having to write an something like that where it only get's run once.

  • Java EE without Application Server

    - by deamon
    Since EJB 3 we have embeddable EJB containers, JPA implementations can be used without an application server, there is Weld for contexts and dependency injection and so on. Since on many systems is only Tomcat available, I wonder, if Java EE could be used without an application server but with a Servlet container like Tomcat. What would I have to do to set up an Java environment? What drawbacks do you see?

  • why develop in windows/desktop application?

    - by Alexander
    Just wondering what your comments are regarding the current trend as everything is moving to the web or even the cloud. The significance of an OS or desktop application is getting less attention than web application. So to those folks out there who still develop windows applications, such as WPF. Why still do it? Why not move to web programming? Silverlight instead for example...
