  • passing values to pages

    - by Indranil Mutsuddy
    Hello friends, What i am trying here is to pass values to other pages. When i include the following code private void Button1_Click(object sender, System.EventArgs e) { // Value sent using HttpResponse Response.Redirect("WebForm5.aspx?Name="+txtName.Text); } if (Request.QueryString["Name"]!= null) Response.write( Request.QueryString["Name"]); everything works fine the name gets displayed. Now if use MemberId instead, though i can see the Id in the Url, but while checking for Null in other page, its true. Whats wrong?? Now I tried the same thing using session i.e. Session["MemberId"] = this.TxtEnterMemberId.Text; if (MemberSex.Equals("M")) Response.Redirect("PatientDetailsMale.aspx",false ); Page_load event of the other page if (Session["MemberId"] != null) mid = Session["MemberId"].ToString(); IT Works..Could u guys explain the behaviour please? P.S. Can anyone give a breif in layman words about SessionId and its usage. Thanking you, Indranil

  • Hooking into DirectX application

    - by x3ro
    Hey there :) I'm currently trying to display some information (as an overlay) to the user inside a DirectX-based game, much like the frame count which Fraps displayed, but I have no clue where to start. I don't expect a full solution to my problem, just a few hints where I can start and where to get more information about the topic ;) Thanks in advance. PS: The project I'm working on is written in C# (.NET 3.5) PPS: To clarify: I mean hooking into any random DX-based game. Start my app, start any game, display some kind of overlay.

  • Do I have to remove VS 2010 beta1 in order to get a web app to work on asp.net 2.0?

    - by Galilyou
    I think the title is enough :). I have VS 2010 beta1 installed, and I wish to run an asp.net mvc application on my local IIS. The problem is, the asp.net 4.0 runtime is selected by default for all the web sites, when I try to change it to asp.net 2.0, I get the following error message: I click yes, then ok, and when I get back to the ASP.NET tab of my site's properties, I see the 4.0 version is selected back again! Do I have to remove VS 2010 in order to get this to work? (hopefully not) Ps: I'm using windows XP and IIS 5.1

  • Why do Java/C# edge out C++ as the recommended language to learn OOP on S.O?

    - by viksit
    I noticed after reading the answers/discussion to this question (What is the best language to learn OOP on?) - that more and more people are recommending C# or Java over C++ to learn OOP on. A simple term search on that answer page results in 10 hits for C++, 21 for C# and 27 for Java. Now, I understand that these 2 languages fix a lot of quirks and issues with C++, and looked up these resources that relate mostly to performance, JVM vs native implementation, systems focus vs applications, manual memory management vs automated et al. My question is - are there any fundamental differences in the OO capabilities of Java/C# vs C++? Or are the former recommended purely due to their generic ease of use/improvements over the latter? Thanks. PS, I'm aware of Java interface inheritance vs C++ multiple inheritance as a difference. I would consider that an implementational one rather than functional.

  • Arduino not able to send serial data back

    - by Casper Marcussen
    Hello everyone So i found out how to connect the arduino to my java program. But using the seriel connections dosent give any useful data back, its either in the wrong format, or just sends it as a box. I've looked at the related questions posted early in here, but none of the tips seems to help. So does anyone know how to send the data between an arduino and a computer using the serieal port? P.S I've used the sample code from the arduino.cc homepage to connect to the serial port.

  • How to mark empty in a single element in a float array

    - by Vineeth Mohan
    I have a large float (primitive) array and not every element in the array is filled. How can i mark a particular element as EMPTY. I understand this can be achieved by some special symbols but still i would like to know the standard way. Even if i am using some special symbol , how will i handle a situation where the actual data item is the value of special symbol. In short my question is how to implement the NULL feature in a primitive type array in java. PS - The reason why i am not using Float object is to achieve a high memory and speed performance. Thanks Vineeth

  • Browser back button broken between hidden div's

    - by Linda
    First of all, these pages will never be on the web but will be in internal memory. They are a group of linked documents---an ebook. http://www.anmldr.com/testdivs When I click on the link in the first div, the second div becomes visible and the first div is hidden. The problem is with the browser's back button. If you then click on the back button, the URL updates but the first div does not show again. How can I correct the back button so that the first div shows? The link from the second div to the first div works fine but it is the browser back button that I do not know how to work with. Thanks, Linda P.S. These are using CSS3 so it is better to use a WebKit based browser.

  • C# Compiler should give warning but doesn't?

    - by Cristi Diaconescu
    Someone on my team tried fixing a 'variable not used' warning in an empty catch clause. try { ... } catch (Exception ex) { } - gives a warning about ex not being used. So far, so good. The fix was something like this: try { ... } catch (Exception ex) { string s = ex.Message; } Seeing this, I thought "Just great, so now the compiler will complain about s not being used." But it doesn't! There are no warnings on that piece of code and I can't figure out why. Any ideas? PS. I know catch-all clauses that mute exceptions are a bad thing, but that's a different topic. I also know the initial warning is better removed by doing something like this, that's not the point either. try { ... } catch (Exception) { } or try { ... } catch { }

  • WeakReferences are not freed in embedded OS

    - by Carsten König
    I've got a strange behavior here: I get a massive memory leak in production running a WPF application that runs on a DLOG-Terminal (Windows Embedded Standard SP1) that behaves perfectly fine if I run it localy on a normal desktop (Win7 prof.) After many unsucessful attempts to find any problem I put one of those directly beside my monitor, installed the ANTs MemoryProfiler and did one hour test run simulating user operations on both the terminal and my development PC. Result is, that due to some strange reasons the embedded system piles up a huge amount of WeakReference and EffectiveValueEntry[] Objects. Here are are some pictures: Development (PC): And the terminal: Just look at the class list... Has anyone seen something like this before and are there known solutions to this? Where can I get help? (PS the terminals where installed with images prepared for .net4)

  • Solr date field tdate vs date?

    - by user550178
    So I have a question about Solr's field date types which is pretty straight forward: what's the difference between a 'date' field and a 'tdate' one? The schema .xml claims that 'For faster range queries, consider the tdate type' and 'A Trie based date field for faster date range queries and date faceting. ' Fair enough... but what's the precisionStep="6" all about? should i change this? does it change the way i would create the query in case I use the tdate? What's the real advantage or what does Solr do that makes it better? P.S went through google, Solr manual, solr wiki and the java docs without any luck so I'd appreciate a kind and explanatory answer :)...

  • Why doesn't Microsoft release a 'proper' AJAX grid for ASP.Net

    - by Maxim Gershkovich
    Why doesn't Microsoft release a 'proper' AJAX grid for ASP.Net either as part of Visual Studio or the AJAX control toolkit? Has there been any discussion that anyone is aware of regarding this issue? Also does anyone have any open source suggestions for 'proper' AJAX gridviews? So far I have found one.... http://dotnetslackers.com/projects/AjaxDataControls/Default.aspx PS: By proper I mean a grid that actually uses XML responses rather than the nasty html javascript based injection that is the current nastyness of the gridview (EVEN IN VS 2010).

  • How to add a "handle bar" to a sliding div

    - by Josh Brown
    I have a small splash page and have a browser-wide div that acts as a wrapper and have a div inside of #wrapper that is attached to a $.click(); event to slide the wrapper div out to view the browser-size background photo. I'm wanting to implement a small button/link that will slide in on the bottom right corner after the wrapper div is hidden. I know it is probably mainly CSS, but am needing some help. Thanks in advance for your help! PS: Using jQuery as my framework.

  • Create an own "OpenID-like system" Provider

    - by user502052
    I know that Facebook use their own OpenID-like system called "Facebook connect", which you can use to authenticate users on your site, among other features. In my case I have multiple Ruby on Rails applications: users.example.com profiles.example.com photos.example.com ... I would like to use 'users.example.com' as a web service that allows users to authenticate to all my other applications the same way as works "Facebook connect" or OpenID. In few words, 'users.example.com' must works as a "OpenID-like system" for my applications in 'example.com'. Can anyone give me tips and links to some useful resources? P.S.: since I am a newbie in this matter, I do not know if I'm saying things that make sense. So someone could help me to understand (if I am wrong) ...

  • What is the fastest way to learn JPA ?

    - by Jacques René Mesrine
    I'm looking for the best resources (books, frameworks, tutorials) that will help me get up to speed with JPA. I've been happily using iBatis/JDBC for my persistence needs, so I need resources that will hopefully provide comparable functions on how to do things. e.g. how to I set the isolation level for each transaction ? I know there might be 10 books on the topic, so hopefully, your recommendation could narrow down to the best 2 books. Should I start with OpenJPA or are there other opensource JPA frameworks to use ? P.S. Do suggest if I should learn JPA2 or JPA1 ? My goal ultimately is to be able to write a Google App Engine app (which uses JPA1). Thanks Jacque

  • Menubar + Commandbar on WM 5.0 and WM 6.5.3

    - by heller.rublog
    I'm developing a Windows Mobile application, and I faced a problem with CCommandBar that combines toolbar and menubar. Well, I mean the following: m_wndCommandBar.InsertMenuBar(IDR_MAINFRAME); m_wndCommandBar.LoadToolBar(IDR_MAINFRAME); I have only one root menu option in my command bar and some buttons in toolbar. It works perfectly on Windows Mobile till version 6.5.3, but on WM 6.5.3 all toolbar buttons have the same dimensions as the menu item: screen. Is it possible to force WM 6.5.3 to draw command bar the same way as WM 5.0 did? Of cource I can use only toolbar and throw away my menubar, but I want to save the old UI. P.S. I'm sorry for my English mistakes. I was always failing at school :-(

  • Debugging kernel hang

    - by l.thee.a
    I am trying to run an app which is using a kernel mode driver. System locks up every hour and the only way to recover it is a hard reset. Sysrq stops responding, telnet sessions hang and there are no error messages of any kind. Unfortunately the board does not have ejtag support. I have been trying to isolate it functionally, but this is like looking for a needle in a hay stack. Any suggestions? PS: This is a mips linux system (2.6.31).

  • Tomcat JSP(2.0) Document how to stop automaticly closing empty body tags with /> instead of </tagnam

    - by JOKe
    The question is. If I use JSP Documents (or JSP 2.0) and If I put a TAG without a BODY it is automaticly closed I dont want that. so If I have <div id=....> </div> it is automaticly converted to <div id=.../> How I can stop this ? I am using tomcat is there any configuration about that ? P.S. the reason to want to stop it is because it simple "fuckes" the JQuery stuffs that the designer company are using.

  • Strange error with CreateCompatibleDC

    - by sevaxx
    Maybe this is a foolish question, I can't see why I can not get a DC created in the following code : HBITMAP COcrDlg::LoadClippedBitmap(LPCTSTR pathName,UINT maxWidth,UINT maxHeight) { HBITMAP hBmp = (HBITMAP)::LoadImage(NULL, pathName, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION); if (!hBmp) return NULL; HDC hdc = (HDC)GetDC(); HDC hdcMem = CreateCompatibleDC(hdc); if (!hdcMem) { DWORD err = GetLastError(); } ... ... ... The bitmap hBmp is loaded fine and hdc has a valid value. But the call to CreateCompatibleDC() returns a NULL pointer. Then, GetLastError() returns 0 ! Anybody can guess what's going on here , please ? PS : There are no memory allocations or GDI routines called before this one...so I think memory leaks should be ruled out.

  • Problem about socket communication

    - by Ahmet Altun
    I have two separate socket projects in VS.NET. One of them is sender, other one is receiver. After starting receiver, i send data from sender. Although send method returns 13 bytes as successfully transferred, the receiver receives 0 (zero). The receiver accepts sender socket and listens to it. But cannot receive data. Why? P.S. : If sender code is put in receiver project, receiver can get data, as well.
