  • Is ther a Designer for MFC in Visual Studio like for windows forms in .NET?

    - by claws
    Hello, I'm a .NET programmer. I've never developed anything in MFC. Currently I had to write a C++ application (console) for some image processing task. I finished writing it. But the point is I need to design GUI also for this. Well, there won't be anything complex. Just a window with few Buttons, RadioButtons, Check Boxes, PicturesBox & few sliders. thats it. I'm using VS 2008 and was expecting a .NET style form designer. Just to test, I created a MFC project (with all default configuration) and these files were created by default: ChildFrm.cpp MainFrm.cpp mfc.cpp mfcDoc.cpp mfcView.cpp stdafx.cpp Now, I'm unable to find a Designer. There is no View Designer. I've opened all the above *.cpp and in the code editor right clicked to see "Designer View". ToolBox is just empty because I'm in code editor mode. When I built the project. This is the window I get. How to open a designer?

  • How to implement async pattern in windows forms application?

    - by Alkersan
    I'm using an MVC pattern in winforms application. I need to call remote service asynchronously. So On some event in View I invoke corresponding Presenter method. In Presenter I call BeginInvoke method of service. But to View must be updated only in Main Thread. I could actualy point CallBack to some function in View, and update it`s controls state, but this conflicts with MVP pattern - View must not be responsible for data it carries. This callback function must be in Presenter. But how then invoke View in Main Thread?

  • How to implement a ilike Facebook system without user authentication and still prevent users from cheating ?

    - by fabien7474
    Hi, I am trying to implement something done in almost any website out there : a 'ilike' button (like Facebook) that does not require user authetication to be used for any article of my website written in Grails. I don't want to use any external solution, so I need to implement it myself (or use a grails plugin). So my question is : What does it take to implement this 'ilike' button and prevent users from cheating? For instance, do I need to store local cookies (I suppose yes)? Do I need to check the session ID and IP of the HTTP request? Any well-known implementation are welcomed. Thank you very much for your help.

  • Small, editable table of strings. Which Forms control do I want? (.NET)

    - by I. J. Kennedy
    I have a small array of structs, each struct has three fields, all strings. I want to display these structs in a grid, let the user edit the strings a la Excel, and then retrieve the edited strings of course. Which WinForms control is best for this? Tried a DataGridView but setting the DataSource to the array of structs doesn't seem to work. There are myriad controls with similar names but I can't figure out what does what. All the examples I've found are geared toward using a database as the data source--I just have a simple array.

  • Silverlight 4 webclient authentication - anyone have this working yet?

    - by Toran Billups
    So one of the best parts about the new Silverlight 4 beta is that they finally implemented the big missing feature of the networking stack - Network Credentials! In the below I have a working request setup, but for some reason I get a "security error" when the request comes back - is this because twitter.com rejected my api call or something that I'm missing in code? It might be good to point out that when I watch this code execute via fiddler it shows that the xml file for cross domain is pulled down successfully, but that is the last request shown by fiddler ... public void RequestTimelineFromTwitterAPI() { WebRequest.RegisterPrefix("https://", System.Net.Browser.WebRequestCreator.ClientHttp); WebClient myService = new WebClient(); myService.AllowReadStreamBuffering = true; myService.UseDefaultCredentials = false; myService.Credentials = new NetworkCredential("username", "password"); myService.UseDefaultCredentials = false; myService.OpenReadCompleted += new OpenReadCompletedEventHandler(TimelineRequestCompleted); myService.OpenReadAsync(new Uri("https://twitter.com/statuses/friends_timeline.xml")); } public void TimelineRequestCompleted(object sender, System.Net.OpenReadCompletedEventArgs e) { //anytime I query for e.Result I get a security error }

  • REST authentication S3 like hmac sha1 signature vs symetric data encryption.

    - by coulix
    Hello stackers, I was arguing about an S3 like aproach using authorization hash with a secret key as the seed and some data on the request as the message signed with hmac sha1 (Amazon S3 way) vs an other developer supporting symetric encryption of the data with a secret key known by the emiter and the server. What are the advantage of using signed data with hmac sha1 vs symetric key other than the fact that with the former, we do not need to encrypt the username or password. What would be the hardest to break ? symetric encryption or sha1 hashing at la S3 ? If all big players are using oauth and similar without symetric key it is sure that there are obvious advantages, what are those ?

  • In forms application, is there any Alternative to MsgBox?

    - by GuruC
    I like how MsgBox stops all further processing until it's clicked but I don't like how it pops that little msgbox in the middle of the screen, which I then have bring to the front if there is a window covering it. Is there a way to do something like a msgbox but keep it on my Form (which is always in view) so I can go ahead and click a button on the form instead of having to bring the little msgbox window on top of windows that may be covering it. I use the msgbox to inform me that a certain situation has happened, which I manually fix and when I'm done I click the MsgBox to continue processing. It'd be nice to have this button right on the form.

  • No event is firing when placing a custom data bound control in DataRepeater control in Windows forms

    - by Remo
    Hi, Custom events in a custom data bound control are not firing in DataRepeater control. When I debug it I found that the DataRepeater Control recreates the control using Activator.CreateInstance and Copies the Properties and Events. In my case copying events doesn't copy the custom events that I hooked in. For example public class MyClass : Control { public event EventHandler MyEvent; protected virtual void OnMyEvent() { if(this.MyEvent != null) { this.MyEvent(this,EventArgs.Empty); } } private int selectedIndex= -1; public int SelectedIndex { get { return this.selectedIndex; } set { if(this.selectedIndex != value) { this.selectedIndex = value; this.OnMyEvent(); } } } // // DataBinding stuff goes here // } public Form1() { InitialiseComponent(); ArrayList list = new ArrayList(); list.Add("one"); this.dataRepeater1.DataSource = list; // One Repeater MyClass test = new Myclass(); test.DataSource = GetDataTable(); this.dataRepeater1.ItemTemplate.Controls.Add(test); test.MyEvent +=new EventHandler(test_MyEvent); } // This Event should fire when selected index of Datatable is changed and is firing when placed directly in the form and not firing when place in DataRepeater control/////////////////////// private void test_MyEvent(object sender, EventArgss e) { // This event is not fired/////////////////////// } private DataTable GetDataTable() { ..// Create a data Table and return } Any help Appreciated. Thanks,

  • How can I use EF in windows forms to insert new data ?

    - by Al0NE
    Hi Maybe it's simple question, but it's my first time with EF + win app so ... I'm building win app with EF by adding edmx as data source then drag and drop the tables to get navigator and binding source .. when I press the add button in the navigator it allows me to enter new data but when I save the context I get NULL data for all fields except the auto increment field ( the ID field ).... What should I do to save many entries ...? DO I have to loop over all the entities in the binding source and add them to the context ?? Thanx in advance Update: I forgot to say that when i use data grid view it adds the items correctly but with "Details" it didn't ..

  • How to define default values optional fields in play framework forms?

    - by natalinobusa
    I am implementing a web api using the scala 2.0.2 play framework. I would like to extract and validate a number of get parameters. And for this I am using a play "form" which allows me to define optional fields. Problem: For those optional fields, I need to define a default value if the parameter is not passed. The code is intended to parse correctly these three use cases: /test?top=abc (error, abc is not an integer) /test?top=123 (valid, top is 123) /test (valid, top is 42 (default value)) I have come up with the following code: def test = Action { implicit request => case class CData(top:Int) val p = Form( mapping( "top" -> optional(number) )((top) => CData($top.getOrElse(42))) ((cdata:CData) => Some(Some(cdata.top))) ).bindFromRequest() Ok("all done.") } The code works, but it's definitely not elegant. There is a lot of boiler plate going on just to set up a default value for a missing request parameter. Can anyone suggest a cleaner and more coincise solution?

  • MS Access 07 - Q re lookup column vs many-to-many; Q re checkboxes in many-to-many forms

    - by TBinLondon
    Hello, I'm creating a database with Access. This is just a test database, similar to my requirements, so I can get my skills up before creating one for work. I've created a database for a fictional school as this is a good playground and rich data (many students have many subjects have many teachers, etc). Question 1 What is the difference, if any, between using a Lookup column and a many-to-many associate table? Example: I have Tables 'Teacher' and 'Subject'. Many teachers have many subjects. I can, and have, created a table 'Teacher_Subject' and run queries with this. I have then created a lookup column in teachers table with data from subjects. The lookup column seems to take the place of the teacher_subject table. (though the data on relationships is obviously duplicated between lookup table and teacher_subject and may vary). Which one is the 'better' option? Is there a snag with using lookup tables? (I realize that this is a very 'general' question. Links to other resources and answers saying 'that depends...' are appreciated) Question 2 What attracts me to lookup tables is the following: When creating a form for entering subjects for teachers, with lookup I can simply create checkboxes and click a subject for a teacher 'on' or 'off'. Each click on/off creates/removes a record in the lookup column (which replaces teacher_subject). If I use a form from a query from teacher subject with teacher as main form and subject as subform I run into this problem: In the subform I can either select each subject that teacher has in a bombo box, i.e. click, scroll down, select, go to next row, click, scroll down, etc. (takes too long) OR I can create a list box listing all available subjects in each row but allowing me to select only one. (takes up too much space). Is it possible to have a click on/off list box for teacher_subject, creating/removing a record there with each click? Note - I know zero SQL or VB. If the correct answer is "you need to know SQL for this" then that's cool. I just need to know. Thanks!

  • How can I tell when the Text of a System.Windows.Forms.GroupBox wraps to the next line?

    - by fre0n
    I'm creating a GroupBox at runtime and setting its Text property. Usually, the text is only on one line, but sometimes it wraps. The problem is that the controls contained in the GroupBox cover up the GroupBox's text. What I'd like to do is determine if and when the text wraps. Specifically, I'd like to determine how much extra height the wrapped text takes up as compared to a single line. That way, I can reposition the GroupBox's controls and adjust its height. Initially, I thought I'd do this by calling the GroupBox's CreateGraphics() method, and using the Graphics to measure the string. Something like this: private void SetGroupBoxText(GroupBox grp, string text) { const int somePadding = 10; Graphics g = grp.CreateGraphics(); SizeF textSize = g.MeasureString(text, grp.Font); if (textSize.Width > (grp.Width - somePadding)) { // Adjust height, etc. } } The problem is that the size generated by g.MeasureString(text, grp.Font) doesn't seem to be accurate. I determined that it wasn't accurate by putting enough of a single character to cause a wrap, then measuring the resulting string. For example, it took 86 pipes (|) to until a wrap happened. When I measured that string, its width was ~253. And it took 16 capital W's to force a wrap - its string had a width of ~164. These were the two extremes that I tested. My GroupBox's width was 189. (a's took 29 and had a width of ~180, O's took 22 and had a width of ~189) Does anyone have any ideas? (hacks, WinAPI, etc. are welcome solutions)

  • How do I avoid nesting forms when offering inline editing of lists with checkboxes for mass updates.

    - by adam
    A lot of sites offer the ability to edit lists of items inline as well as allowing multiple items to be selected via checkboxes and have an action performed all at once e.g. delete, mark as spam etc. But how do you implement this without violating html rules. I need one form for the checkboxes with individual submit_tags for the mass actions. But after a user clicks on an item in the list, another form via Ajax will be inserted within the checkbox form. How do I avoid doing this? I'm using rails and jQuery.

  • Regular Expression to recognise truncated forms of search string?

    - by Moonshield
    I'm trying to formulate a regular expression which will recognise the search term truncated by any number of characters from the right. For example, if the search term is "pickle", the regex should recognise "pi", "pick" but not "pickaxe". Initially I came up with the following: p(i(c(k(l(e)?)?)?)?)? That works perfectly, but seems a crude way of doing it. Is there a better way of doing this? I had a look around for something similar to what I want, but I'm not entirely sure what to search for.
