  • WPF/C#: How to simplify the use of codes when calling a function (Generating Images)

    - by eibhrum
    I created a function in one of my application that allows to generate an image (in WPF) by getting the 'source path' from the database that I am using: public void ShowImageThumb() { try { cn = new MySqlConnection(); cn.ConnectionString = ConfigurationManager.AppSettings["MyConnection"]; cn.Open(); MySqlCommand cmd = new MySqlCommand(); cmd.Connection = cn; cmd.CommandType = CommandType.Text; cmd.CommandText = "SELECT thumb FROM album WHERE thumbNo=1"; MySqlDataAdapter adp = new MySqlDataAdapter(); adp.SelectCommand = cmd; DataTable dt = new DataTable(); adp.Fill(dt); MySqlDataReader r = cmd.ExecuteReader(); while (r.Read()) { BitmapImage bmi1 = new BitmapImage(new Uri(r[0].ToString(), UriKind.Relative)); image1.Source = bmi1; } r.Close(); cn.Close(); } catch (Exception err){ System.Windows.MessageBox.Show(err.Message); } finally { } } Take a look on my SQL statement. I put a WHERE thumbNo=1 which allows the function to get 1 record. You see, I do have at least 10 records - file paths listed in that table. I just wanna ask if there's a possible way to make my SQL statement something like this: SELECT thumb FROM album; while having this piece of code inserted in my function: BitmapImage bmi2 = new BitmapImage(new Uri(r["second record?"].ToString(), UriKind.Relative)); image2.Source = bmi2; //something like this BitmapImage bmi3 = new BitmapImage(new Uri(r["third record?"].ToString(), UriKind.Relative)); image3.Source = bmi3; //something like this and so on and so forth, without ending up creating 10 different functions for 10 records. ShowImageThumb2(); . . // will not do this . ShowImageThumb10(); Sorry for the lengthy post. I hope somebody could answer back. Thanks!

  • mixed declarations and codes

    - by gcc
    When I compile function with "gcc -o dene -Wall -ansi -pedantic-errors dene.c",gcc emits no error.(can you look a line which starts with char ....,in if loop,) static void remove_negation(char *s,char *s1) { char **cmainp=malloc(sizeof(char*)*1); int len=0;int d=0; int i=0; cmainp[0]=malloc(sizeof(char)*300); len=strlen(s); for(i=0;i<len;++i) { if(s[i]=='-') if(i==0 || s[i-1]==',') /*look*/ {char *p=malloc(sizeof(char)*3); /*look*/ ++i; p[0]=s[i]; p[1]='\0'; strcat(s1,","); strcat(s1,p); free(p); continue; } cmainp[0][d]=s[i]; ++d; } cmainp[0][d+1]='\0'; strcpy(cmainp[0],s); free(cmainp[0]); } But,when compile above function being reformatted with gcc,gcc emits that error "dene.c:10: error: ISO C90 forbids mixed declarations and code" static void remove_negation(char *s,char *s1) { char **cmainp=malloc(sizeof(char*)*1); /*look*/ cmainp[0]=malloc(sizeof(char)*300); /*look*/ int len=0;int d=0; int i=0; len=strlen(s); for(i=0;i<len;++i) { if(s[i]=='-') if(i==0 || s[i-1]==',') {char *p=malloc(sizeof(char)*3); ++i; p[0]=s[i]; p[1]='\0'; strcat(s1,","); strcat(s1,p); free(p); continue; } cmainp[0][d]=s[i]; ++d; } cmainp[0][d+1]='\0'; strcpy(cmainp[0],s); free(cmainp[0]); } And last one,gcc emits following errors dene.c:16: error: expected expression before ‘char’ dene.c:20: error: ‘p1’ undeclared (first use in this function) dene.c:20: error: (Each undeclared identifier is reported only once dene.c:20: error: for each function it appears in.) static void remove_negation(char *s,char *s1) { char **cmainp=malloc(sizeof(char*)*1); /*look*/ cmainp[0]=malloc(sizeof(char)*300); /*look*/ int len=0;int d=0; int i=0; len=strlen(s); for(i=0;i<len;++i) { if(s[i]=='-') /*look*/ char *p=malloc(sizeof(char)*3); /*look*/ if(i==0 || s[i-1]==',') { ++i; p[0]=s[i]; p[1]='\0'; strcat(s1,","); strcat(s1,p); free(p); continue; } cmainp[0][d]=s[i]; ++d; } cmainp[0][d+1]='\0'; strcpy(cmainp[0],s); free(cmainp[0]); } question is why there are differences between them.

  • merging two small pieces of jquery codes

    - by Billa
    Following are two pieces of jquery code. First one prints a text message when clicked on a link, and the second slides down a div when click on a link. I want to merge second code into first one, so that when I click the link, it displays the message (as the first code does), and also slides down the #votebox (as done in second code, and show content in that. I will be very thankful for any help. $("a.vote_up").click(function(){ the_id = $(this).attr('id'); $("span#votes_count"+the_id).fadeOut("fast"); $.ajax({ type: "POST", data: "action=vote_up&id="+$(this).attr("id"), url: "votes.php", success: function(msg) { $("span#votes_up"+the_id).fadeOut(); $("span#votes_up"+the_id).html(msg); $("span#votes_up"+the_id).fadeIn(); //Here, I want to slide down the votebox and content div (from code below). } }); }); The following code slides down votebox div and displays content in it, I want to include that in the above code. $("a.vote_up").click(function(){ var id=$(this).attr("id"); var name=$(this).attr("name"); var dataString = 'id='+ id + '&name='+ name; //I want to include this votebox in above code. $("#votebox").slideDown("slow"); $("#flash").fadeIn("slow"); $.ajax({ type: "POST", url: "rating.php", data: dataString, cache: false, success: function(html){ $("#flash").fadeOut("slow"); //and want to use this div as well. $("#content").html(html); } }); }); Thanks for any help.

  • BULK SMS, Long Codes (VMN MSIDN), T-mobile?

    - by John
    Does any US wireless carrier offer individuals or companies with a direct connection to the SMSC? The number is 747-772-3101 (repalce 7's with 6's) This number is registered to t-mobile, also verified by t-mobile to be a valid subscriber sending 160,000+ text messages monthly and that all they have is an unlimited text messaging plan on top of the cheapest voice plan. This company of the number verified to me that they don't use gsm modems as they are too slow. So I know it's possible but who would I contact, Sales or anyone else reachable through a 1-800 is ignorant to these services and developer.t-mobile is worthless and doesn't reply to emails. Any info??

  • Body CSS Gradient that Stops and Continues as Solid Color

    - by Alfo
    Something similar to this question has been asked here - HTML/CSS Gradient that stops at a perticular height and continues further with a solid color, but as far as I can see this doesn't work when using it on the body for a background color - which is what I want to achieve. Specifically, I would like it to be light blue at the top of the page, gradient into dark blue 200px further down, and then continue in dark blue for ever. Thanks to anybody who can help, Alfo.

For example is something like this valid in XHTML 5? <!DOCTYPE html PUBLIC "WHAT SHOULD BE HERE?"

  • What does ZIP stand for (the compression format, not the postal codes)

    - by codymanix
    Does anybody know for what the acronym ZIP stands for which was and is used in programs like PKZIP and GZIP? There is a compression algorithm named Lempel-Ziv-Welch-Algorithm (LZW) maybe the guy named Ziv invented together with other people ZIP? I cannot find anything about it, maybe its not an abbreviation but instead it just means "to zip files" but I think originally there was more about it..

  • GDI+: Set all pixels to given color

    - by Charles
    What is the best way to set the RGB components of every pixel in a System.Drawing.Bitmap to a single, solid color? If possible, I'd like to avoid manually looping through each pixel to do this. Note: I want to keep the same alpha component from the original bitmap. I only want to change the RGB values. I looked into using a ColorMatrix or ColorMap, but I couldn't find any way to set all pixels to a specific given color with either approach.

  • Sitecore E-Commerce Module - Discount/Promotional Codes

    - by Zachary Kniebel
    I am working on a project for which I must use Sitecore's E-Commerce Module (and Sitecore 6.5 rev. 120706 - aka 'Update 5') to create a web-store. One of the features that I am trying to implement is a generic promotional/discount code system - customer enters a code at checkout which grants a discount like 'free shipping', '20% off', etc. At the moment, I am looking for some guidance (a high-level solution, a few pseudo-ideas, some references to review, etc) as to how this can be accomplished. Summary: What I am looking for is a way to detect whether or not the user entered a promo code at a previous stage in the checkout line, and to determine what that promo code is, if they did. Progress Thus Far: I have thoroughly reviewed all of the Sitecore E-Commerce Services (SES) documentation, especially "SES Order Line Extension" documentation (which I believe will have to be modified/extended in order to accomplish this task). Additionally, I have thoroughly reviewed the Sitecore Community article Extending Sitecore E-Commerce - Pricing and believe that it may be a useful guide for applying a discount statically, but does not say much in the way of applying a discount dynamically. After reviewing these documents, I have come up with the following possible high-level solution to start from: I create a template to represent a promotional code, which holds all data relevant to the promotion (percent off, free shipping, code, etc). I then create another template (based on the Product Search Group template) that holds a link to an item within a global "Promotional Code" items folder. Next, I use the Product Search Group features of my new template to choose which products to apply the discount to. In the source code for the checkout I create a class that checks if a code has been entered and, if so, somehow carry it through the rest of the checkout process. This is where I get stuck. More Details: No using cookies No GET requests No changing/creating/deleting items in the Sitecore Database during the checkout process (e.g., no manipulation of fields of a discount item during checkout to signal that the discount has been applied) must stay within the scope of C# Last Notes: I will update this post with any more information that I find/progress that I make. I upgrade all answers that are relevant and detailed, thought-provoking, or otherwise useful to me and potentially useful to others, in addition to any high-level answers that serve as a feasible solution to this problem; even if your idea doesn't help me, if I think it will help someone else I will still upgrade it. Thanks, in advance, for all your help! :)
