Web Forms :: Display Image Based On Database Entry?
Feb 15, 2011
I have these 4 images along with the descriptions:
Flag
Description
Green Flag (WBGTI of 80 to 84.9 degrees F): Heavy exercises, for unacclimatized personnel, will be conducted with caution and under constant supervision.
Yellow Flag (WBGTI of 85 to 87.9 degrees F): Strenuous exercises or physical labor will be curtailed for unacclimatized, newly assigned personnel in their first 3 weeks. Avoid outdoor classes or work in the sun.
Red Flag (WBGTI of 88 to 89 degrees F): All PT or very strenuous work will be curtailed for those not thoroughly acclimatized by at least 3 weeks. Personnel not thoroughly acclimatized may carry on limited activity not to exceed 6 hours per day.
Black Flag (WBGTI of 90 and above degrees F): All nonessential physical activity will be halted.
1 page to set the flag condition and another page to display the flag and the description. I am new to coding and Im not sure how to do it. I do have MSSQL Server 2005 that I can use to store the data.
I am really new at this. I have a site that I would like to display a certain image (a colored flag) based on an entry in the database. I have a folder called flag_images, I'm using VB, and MSSQL Server 2005. I have never done anything like this. There are 4 images total. They are green.gif, yellow.gif, red.gif, and black.gif. The database table is called tblflag. There are three columns. ID (int), time_set (datetime), and flag_color (nvarchar).
I would like to display the green flag if the column flag_color is equal to green and so on for the other colors. Only one flag will be displayed at a time.
I have to create a simple application which scans, displays and stores the info from a barcode. I have been able to sort the scanning and display part of this application but I need to know how to store the infromation entered into a textbox to a database and then be able to display the stored data as a list at a later stage.E.G. Once the "STORE" button is clicked, the information/text within the textbox is stored to a database. Once the "VIEW STORED DATA" button is clicked, the stored information in the database is displayed as a list.I am a complete beginner when it comes to creating web applications using asp.net. Also, the type of database to use (i.e. sql, wamp.etc) and how to link it to my application is also puzzling.
In my asp.net+vb web with access database there is a page which displays data as per query string and the string is PNO and all data is correctly displayed in gridview and dataview. there is a Image1.ImageUrl and i used the following code but it is not working
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Dim PNO As String PNO = Request.QueryString("PNO") Image1.ImageUrl = "C:/wing/Photos/" + PNO + ".jpg" End Sub
I know this might sound like a simple quesiton, but I am having problems allowing me to upload images along with other information (name, image, biography, wbsite links) to a sql server database, as well as showing images from the database using a drop list control feature. I am using [URL] for hosintg. VB language.
i m displaying an image in gridview based on condition from sql table. That is if the colum named "availabillity" is A the image will be red n if the value is "NA" the image will be green. i am using RowDataBound event.
but i am getting error as "Cannot implicitly convert type 'System.Web.UI.WebControls.DataControlRowType' to 'bool'".
i am using MSSQL Server 2005 with VB in my codebehind. I have an application that I have written as a time tracking system that uses SQL Membership provider to secure the site with forms authentication. I want to add additional functionality to the site. My company has a intranet SharePoint site. I want to add something on the front page of the SharePoint site that will allow the users to clock-in/out without having to login to the application. I have a users table that is not part of the SQL Membership Provider that holds detailed information about the employees. There is a column in that table that identifies users as being able to use the clock-in system. I want to be able to display a clock-in/out button on the paged based on that column. Not all users have the ability to clock-in as their time does not need to be tracked.
I have built some back-end code to retrieve an image from a SQL Server database. I want to display this image on my web form based on the currenct selected value of a gridview control.
I have a page called GetImage.aspx which takes two querystring parameters, entityId and entityType. entityId is the GridView.SelectedValue and entityType is simply "T". My code for GetImage.aspx looks like this:
[Code]....
The image is not displayed, however I can see the stored procedure being executed on the database server with the correct ID when I select an item in the GridView, so that part is working, but the display of the image isn't.
I have a online game (written in ASP) which i have finally decided to convert to ASP.NET. However i cannot seem to link the login ID's of users to their specific details in the database. I.E when Joe Bloggs logs in, he will be shown the team information for just his club, not every club. in ASP I use code similar to this below
[Code]....
im not convinced that is the right syntax to be using, but when i execute the code in Query Builder it is showing me the correct data (that i expect to see). So im wondering if there is something else im missing? Is there something extra that i need to be adding in Web.Config file or elsewhere?
I have a detailsview form which passes data to a sql database. What I'd like to do is present a message when the number of rows in the destination table exceeds a specified number (40) or redirect the user to another page.
Am displaying the contents of a folder(folders n files) in a gridview.In the gridview,file/foldername ,type ,size ,Last modified date columns are displayed.the datasource for this gridview is supplied manually through a datatable.
I need to display folder/file images beside folder/filename.if the datasource is from a database we can give a if condition in the following way.
[code]....
But here in itemtemplate I am binding the data using bind expression instead of Eval .So I could not give if condition here.
How can I display folder or file image based on a condition ?the datasource is provided manually to the gridview not from a database.
in my asp.net_vb web there is a text box (textbox1) in which a date is dispalyed from database (eg 21-Mar-2012) in another text box (textbox2) i want to display
if the date is less than 30 Jun then the textbox2 should display 1 Jul+the year of textbox1
if the textbox1 date is greater than 30 Jun the text box2 should display 1 Dec + the year of textbox1
I need displaying my image file stored from my database into the image control. I've had read some articles and watch video tutorial which there were perfectly working and I followed it but I wasn't able to make it work. The image control just displayed blank. I used Generic Handler to retrieve the image file from my database based on the articles and tutorials I've got. here are my codes below:
Generic Handler:
Code: <%@ WebHandler Language="C#" Class="ShowImage" %> using System; using System.Configuration; using System.Drawing; using System.Drawing.Imaging;
After saving image in db how can we retrieve it in gridview like thumbnail size image and by clicking on image in gridview its open as preview. How can we do this in asp.net using c#.
Suppose I have two page admin and home,in admin page one upload control and in home page gridview,I will select the image and upload from admin and after uploading show the image in home page gridview ...
I have a database which signature images. Images are saved in binary.
I want to retrieve the image and display in an image control. I am kinda new to ASP and what seemed so simple has suddenly become a real problem.
The at the botom is how I would do it on a winform. Unfortunately I have no picturebox control in .asp. So how do I get the image stream into image1.imageurl?
Is there a way to put the stream into a session variable and then point to that as a url?
for instance replacing the last line below with this and then pointo to it from image1.imageurl?
