I'm trying to dynamically load an image from my code behind file, however I want to be able to resize the image thus reducing the file size sent to the client. I've come across a few samples but without much luck. So far I have the following:
[Code]....
Unfortunately I now need to load this image into control panel...but nowhere can I find how to do this.
Do you think it is wise to load the background-body image dynamically in a CMS application from SQL Server 2005? Granted I would have to generate a sql statement based on size of the page to show the correct image. Anyone run into any pitfalls?
View 1 Repliesin my source view of my web page I am using some images. Right now I use the code:
HTML Code:
<img class="smallIcon" src="skins/itsoft-images/small-icon.png" alt="Small Icon" width="20px" height="20px" />
I use this image many times in my pages, as well as other images. I don't want to use a path like this because if I ever change the location of the images, I will have to update a hundred pages.I would like to place the path to the image in my web.config file, and have the code load from there. I'm use to doing it in PHP but I can't figure it out in .Net.
Something like:
HTML Code:
<img class="smallIcon" src="<%@ ICON_FILE_DIR %>" alt="Small Icon" width="20px" height="20px" />
Is that even possible?
i have an aspx with the following code (i don't want to bother you with unecessary additional code but basically the page will contact a remote proxy server and try to authenticate some requests and then redirect back to another page based on the response status)

View 2 RepliesI have a tab control on my page and on click of tab user control is loaded dynamically.I need to load the javascript file of that user control dynamically. I don't want to add the reference of my js file on parent page.so in my .ascx page load event i added:
System.Web.UI.HtmlControls.HtmlGenericControl js = new System.Web.UI.HtmlControls.HtmlGenericControl("script");
js.Attributes["type"] = "text/javascript";
js.Attributes["src"] = "../../js/DatesJavaScript.js";
Page.Header.Controls.Add(js);
but it is not working.
when I load the web page the image's file size stays the same rather then reduce.

i have two buttons, which point to some onclick-methods in my code-behind file. inside these btn_click-codes i want to start adding pure html-code to my page, which was told to me in this forum having done by using ascx-files. note: there would be no code-behind in case of using the ascx-files.
however i do not see a possibility to load these ascx-files within btn_click-code? how to do?
in order to give you an idea of my html-code i have pasted two of them here:
[Code]....
maybe this is the complete wrong approach (as i.e. i believe that body-tags should not be included in .ascx-code). in this - how to do better?
Precisely and concisely, I have aspx page that has only one button "Generate". If the user clicked on this button, one HTML page should be created.
The created HTML page should have title "Home" and the Body should contain "Hello World".
1) What is the code that should be written inside "Generate" button in order to accomplish this functionality?
2) Assuming the HTML page gets created, How to store it inside specific folder on the local drive? Or how to store it inside DB?
We have encountered this difference in file creation while using a HttpHandler Versus a Code Behind Aspx page. We are reading a saved jpg/png picture as byte array from a 'Image' field in sql server database and create a physical file in the server. Both the Aspx Page and Httphandler use the same code pasted below.
//Begin
int docID = Convert.ToInt32(Request.QueryString["DocID"]);
var docRow = documentDB.GetDocument(docID);
// Retrieve the physical directory path for the Uploads subdirectory
string destDir = Server.MapPath("../../Uploads").ToString() + "\";
string strFileName = destDir + DateTime.Now.ToFileTime() + "_" + docRow.DocName.ToString();
FileStream fs = new FileStream(strFileName, FileMode.CreateNew, FileAccess.Write);
fs.Write(docRow.DocData, 0, docRow.DocData.Length);
fs.Flush();
fs.Close();
// End
After the file is created, it is viewable as a jpg/png Image only in Aspx Code Behind. While in case of HttpHandler it is not a valid Image.
Have a look at below link. In that page if you mouse over on any thumbnail image a div opens with that image details with larger size. But there is a point to notice usually when an image gets downloaded in the browser we see that the image loads in parts from top to bottom. In this case the whole is loaded but in blurred state and gets cleared after fully downloaded.

I just wanted to know how this is achived? Does it require to code something or it is any javascript or dhtml?
using vb.net/asp.net 2005
I've been tasked with creating a page where the user can do the following in this order:
1. browse to and select a jpg image
2. preview the image that the user just selected
3. if the user is happy with the preview then click the GO button to load the image to the Image folder.Does anyone have any good examples or sample code of how to do this?
I have this in my code-behind file (VB.NET):
[Code]....
Here is the HTML source of the part of the page:
[Code]....
Where that comment in the code-behind file says "REFERENCE IN CODE HERE", that is where I want to set the value of the "remLen3" input (client-side control) to "30 characters left."I obviously left out irrelevant things like inserting the txtNewComment.Text into the database. But what's going on here is when the user types in something into the txtNewComment text box, I'm using javascript to change the value of the remLen3 control.My problem is that when I submit the text from the txtNewComment textbox to the database and set the txtNewComment.Text equal to Nothing, I don't know how to reset the remLen3 field value back to saying "30 characters left.". I already tried to add a "runat="server"tag to it, but when typing stuff into my txtNewComment textbox it gives me an error. I already tried to figure out what the error meant, so I'm not going to spend time trying to solve it anymore; I would rather just see if there is a workaround to using the runat="server" tag. Maybe do some kind of a CType(FETCH_REM_LEM3_HERE_SOMEHOW, INPUT_TEXT_TYPE??).value = "30 characters left". If there is a way of converting the input text control (remLen3) that way, then how would that be done? I just want to change the value of that field when the server-side button is pushed.
Here is this thing which to me looks possible, but when I searched over the net I couldnt find anything.

I'm having difficulties getting XslCompiledTransform.Load method to take a server path. I googled around and found that I need to do something like:
xslt.Load(System.Web.HttpContext.Server.MapPath(xslPath), XsltSettings.Default, new XmlUrlResolver());
But it returned an error saying HttpContext is null.
I also tried:
xslt.Load(System.Web.HttpServerUtility.MapPath(xslPath), XsltSettings.Default, new XmlUrlResolver());
That also returned an error saying an object reference is required for the non-static field, method, or property 'System.Web.HttpServerUtility.MapPath(string)'
The xslPath has a path that points to a xsl file in Sharepoint Web. I just want XslCompiledTransform to load the xsl file with the server path. Is it possible? If so, what is the proper way or hackish way of doing it?
EDIT: I have access to a SPWeb object which contains the path to the xsl file. However when I check the ServerRelativeUrl, it just says "/MyTree/xsl.xsl". The problem here is I couldn't get the XslCompiledTransform.Load to load the file from SharePoint list.

I'm trying to write some code to use reflection to load new assemblies. I observed the file system with FileSystemWatcher, so that if anything in the folder changed, I can get notified and then reload them.
Firstly I have an assembly filters.dll loaded. Let's say its version is 1.0.0. Then when I have a new one v1.0.1, I paste it into the folder and replace the older one. Of course this fires "Change" event of FileSystemWatcher, and finally lead to assembly reloading.
Everything works fine, but I just want to know, what would happen to the firstly loaded assembly? Get replaced by the newer one? Or still somewhere in the memory?
