i'm trying to build a picture of the day in c#
string m1 ;
Image1.ImageUrl = "~/PictureOfTheWeekImages/+"m1"+.jpg";
and i want to insert the name of the file as a variable that changes with the date ...
my way not working .... i'm sure it somthing like this,
and i'm not sure how to write the url right ..
i'm new to c# and i wanted to know how can i allow user to upload a picture from a text box and a button??
after uploading the picture, how can i save the picture in the database??
**note**the picture i allow user to upload need to be in a fixed size.
I have this code to insert a picture from database into an ImageControl on my ASP.NET form:
strConnString = "server=" + Server + ";database=" + DataBase + ";UID=" + UID + ";password=" + PASS + ";";SqlConnection MyConnection = new SqlConnection(strConnString);SqlCommand MyCommand = new SqlCommand("SELECT Pic FROM MEN WHERE ID=5", MyConnection);MyConnection.Open();SqlDataReader MyReader = MyCommand.ExecuteReader();if (MyReader.Read()){ byte[] m_MyImage = (byte[])MyReader["Pic"]; Response.BinaryWrite(m_MyImage);}
And I have this ImageControl on the form:
<asp:Image Width="88" Height="100" Runat="server" ID="m_Image" NAME="m_Image" />
but when I run the code, I see the picture big on the screen and not in my ImageControl.
i also put this in the form_load:
m_Image.ImageUrl = "MyPhoneBook.aspx?m_Image";my control is: m_Imagemy control ID is: m_Imagemy namespace is MyPhoneBook
but still dont work
I ve an application dat am working on. The section of the upload picture works perfectly on the development environment and also on a test server but the issue comes up when it was hosted life. I started geting an error dat says picture could not be attached. I ve a folder cald Passport and dis ve been working for me on befor now but i dont now the reason y its not working now.

String fileExtension = string.Empty;
String path = Server.MapPath("~/Passport/");
if (fuPassport.HasFile)
{
fileExtension = System.IO.Path.GetExtension(fuPassport.FileName).ToLower();
String[] allowedExtensions = { ".gif", ".png", ".jpeg", ".jpg" };

{
fileOK = true;
}
}

I have a question regarding a situation that occurs with GridView, ObjectDataSource in ASP .NET application. The GridView is linked to the ObjectDataSource and both are included within an UpdatePanel letting the GridView to fill in an asynchronous way from a form in the same page so it gets more rows as the user enters the data:
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="ObjectDataSource1">
<Columns>
<asp:BoundField DataField="Name" HeaderText="Name" ReadOnly="True"
SortExpression="Name" />
<asp:BoundField DataField="Periodicty" HeaderText="Periodicty" ReadOnly="True"
SortExpression="Periodicty" />
</Columns>
</asp:GridView>
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
SelectMethod="GetSessionNames" TypeName="Simulation"></asp:ObjectDataSource>
<asp:Label ID="Label27" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="NewWebSessionButton" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
I start the project with Visual Studio 2008, fill the form and it works correctly. Then I stop the execution: rerun again and the data I entered in the previous run is in the GridView. Is like some sort of cache saved the data from the session before. I checked that EnableCaching property is set to false for the ObjectDataSource. If I Rebuild Web Site in Visual Studio (not just Build) then it works corretly leaving the GridView empty. Is this caused just becuase of Visual Studio? Can it be turned off? And will it happen in the final IIS it will run on?
I want to build a survey system where you can build a form with questions and some answers to these questions and then members who will log in will be able to take the test.
Then i want to present the different results from the test in some diagram or something like that.
It may be obvious to everyone. I am learning this: what is difference between build solution and build website
View 2 RepliesI have a large solution which has multiple apps which all share some common site elements (masterpages, navigation, etc).
Currently, all of these get built into a single DLL
If my structure looks like:
WebRoot
- Common/
- Shared/
- Images/
- App1/
- App2/
- etc
Is there a build tool which will allow me to build WebRoot.dll, App1.dll, App2.dll? I don't believe this is possible in VS2008 or the MSBuild tool.
I have a TFS build set up to deploy an ASP.net project to a test server.The build works great, and deploys to the test server fine, but instead of putting it into the Website directory that my IIS webserver is configured for, it puts the build into Website_20100511.6
Why is the date suffixed to the directory name? Is there a way to turn that off so I can publish directly to the Website?
I need to build web application that will do:1 - build web pages. 1a - build template for page. 2 - add module(by module I mean ContacUs form, Search, Billing System...). Each module can be constructed by submodules or diveded to submodules 2a - build module(add form, textbox, button...) and that all
entered data by user could be saved in dbCan you advise me a DB structure that will contain it allI looked some cms db, but it's NOT this. Please, don't ask why I mess with it. I just need to build it.
In order to avoid having to pass Data that goes in the master page of my site before every view in every controller I have created an ApplicationController that sets the data on its constructor... the problem with this approach is that one of the viewdatas I must pass is the url of the profile Image of the current logged in user.
[Authorize(Roles = "Administrator")]
public abstract class AdministratorController : Controller
{
private IPortalAdministratorServices _servicioPortalAdministrator;
public AdministratorController()
{
_servicioPortalAdministrator = new PortalAdministratorServices();
ViewData["associates"] = _servicioPortalAdministrator.getAssociates();
ViewData["picture"] = _servicioPortalAdministrator.GetPic();
public AdministratorController(IPortalAdministratorServices service)
{
_servicioPortalAdministrator = service;
}
}
and so my companies Controllers wich inherits from AdministratorController now doesnt have to set all that Data upon every View Call.
[Authorize(Roles = "Administrator")]
public class CompaniesController : AdministratorController
{
private ICompaniasServices _service;
public CompaniesController()
{
_service = new CompaniasServices(new ModelStateWrapper(this.ModelState));
}
public CompaniesController(ICompaniasServices service)
{
_service = service;
}
The problem is this: When I try to manually access the Companies Controller without actually being logged in the method GetPic() wont actually be able to get the picture url cause no one is logged in.. and these method is getting called in spite of the Authorize attribute....so now, even after being logged in the ViewData for the picture url has been permanently set to "unknown.png" Some of this code isnt mine.. I just discovered the bug but cant figure out how to fix it.
i add Image control to my WebForm.i insert picture to App_Data.i connect the picture to my Image control in the ImageUrlit seen like this:
<asp:Image ID="Image1" runat="server" Height="94px"
ImageUrl="~/App_Data/Tulips.jpg" Width="209px" />
in the design i see this picture, but when i run the project i dont see the picture.
I am unable to get the background picture to show in my pages. I am trying to do this in the master page using CSS.I have a CSS which contains the following:
body {
background-image: url(../images/background.jpg) no-repeat;
background-attachment: fixed;
margin-top: 0px;
}
I know the CSS is being read because all other styles defined in it are working on the .aspx pages... except of course the background image, the background remains white. (This works perfectly fine in .php pages by the way.)I have been searching online like crazy and all the answers I find, say the above CSS code is the answer... but it is not working!I am using the following:
Microsoft Visual Studio 2008 Version 9.0.30729.1 SP
Microsoft .NET Framework Version 3.5 SP 1
Firefox Version 3.6.6
In one page I have image controls that are showing pics from the web site. This works fine but sometimes, and randomly some pics are not shown. I guess this issue could happen because Im using the IIS 5.1 in my development enviroment and it could be denying some requests. Anyway, I dont know exactly what is happening, so i request help of those who have workaround this fixture.
View 1 RepliesI am inserting a picture into a database, using the following code.
strFileType = Path.GetExtension(filImage.PostedFile.FileName).ToLower();
switch (strFileType)
{
case ".gif":
strMimeType = "image/gif";
break;
case ".jpg":
case ".jpeg":
case ".jpe":
strMimeType = "image/jpeg";
break;
case ".png":
strMimeType = "image/png";
break;
}
//Store the content length
int iDocLength = filImage.PostedFile.ContentLength;
byte[] bDocBuffer = new byte[iDocLength];
//Get stream object
Stream streamImage;
streamImage = filImage.PostedFile.InputStream;
streamImage.Read(bDocBuffer, 0, iDocLength);
cmPerson.CommandText = "INSERT INTO photos VALUES(@referenceid, @image, @imgtype)";
cmPatient.Parameters.AddWithValue("@referenceid", iPersonID.ToString("000000"));
cmPerson.Parameters.AddWithValue("@image", bDocBuffer);
cmPerson.Parameters.AddWithValue("@imgtype", strMimeType);
cmPerson.ExecuteNonQuery();
If in case that the user, did not browser for a picture, then, I have to use the nopho.jpg that is stored in the images/folder of my web app. How am I be able to do this?
Why StyleSheet.css is not displaying the picture depends on the situation. It displays “Taken!“ or "Available!" but no picture. I am using Ajax with asp.net
