You need to put the resource key in the <% block, but not the 'tip' part

Nope, I cant make it work
Ive tried leaving the "Tip('" and "');" outside the <% but it doesnt work
It looks like i cant mix strings and resource keys in the same assignment

This works if i set the value in my resourcekey to "Tip('Text to show')"

<asp:TextBox ID="TextBox1" runat="server" onmouseover="<%$ Resources:Resource, tttProduct_aspx_txtComent %>"></asp:TextBox>

But i wouldnt like to add the whole syntax (Tip('Text');) in the resource file

If i want to leave the "Tip('" and "');" outside my resourcefile and put it all together in my html source, how would it be (If it is possible)?

By the way
What do you think about storing tooltips in a resource file??
Will this be something optimal or will it consume many resources when running the page?

Thanks again

The most straightforward way is to use <%= and then call a method in the code behind which returns the whole string, including the tip part and the resource.

This code:

<asp:TextBox ID="TextBox1" runat="server" Text="<%= FunctionThatReturnsString() %>"></asp:TextBox>
or
<asp:TextBox ID="TextBox1" runat="server" Text='<%= FunctionThatReturnsString() %>'></asp:TextBox>

Outputs the following html:

<input name="TextBox1" type="text" value="&lt;%= FunctionThatReturnsString() %>" id="TextBox1" />

OK, in that case, I guess you need to add the attribute and do it that way. That DOES suck...

Yes it DOES

Ill store in my resource file the whole thing "Tip('Text to show');"

By the way...What do you think of using resourcefiles to store tooltips
My app wont need several languages, im just doing it to keep tooltips in one place

But will this impact my app performance??

Thanks for your help

Urgent question on displaying Binary IMAGE data to a Datagrid in C# ASP.NET

13-Apr-08 19:39

I doubt it will have a major performance impact, and I think factoring out strings is a good practice, I wish I did it more.

Hi, I have a VERY URGENT question on C# in ASP.NET. I am building an ASP.NET WEB application.

Does anyone know how to retreive BINARY image from a SQL Server 2005 Express Database and DISPLAY it on a Datagrid control?

I can manage to retreive the Binary Data, but I have absolutely no idea how it can be placed into the dataset, or accessed via the Databinder.

I can only display regular string data onto a Datagrid Control. This is my method in displaying string data onto a Datagrid:

1. From the Codebehind, I connect to the database.
2. I then use a DATASET and store the retreived data
3. In the HTML page, I use the Databinder to load the data (<%# DataBinder.Eval(Container.DataItem,"NAMEOFDATABASECOLUMN") %>

However this method only works for strings, I need to display Binary Image, can anyone help me?

Thank you!!!

Yes, you need to write a http handler, and have your images link through that. your problem is that an img tag requires a link to the image itself. So, you need to write a http handler that returns that image data, and then your databinding creates the link that that page, with an id that is used to seperately download the image. This means a lot of database hits, a better bet for a high load site is to put the images on your file system and store the path to them in yuor database.

Hi Christian, thanks for your reply (again).

I am afraid I am not very good in ASP.NET (I think you can tell that already), and I am quite lost.

Do you happen to know any sites on the web with similar examples?

Many thanks again.

Sorry, but one last thing, I see that the example you provided is using VS.NET 2005, should I be worried if I am using VS.NET 2003? Thanks!!!

That would mean that you can't use the project provided, but the overall concept will be the same.

It's not LIKE a javascript alert, a javascript alert is your only option in ASP.NET.

Well, step one is to fix the code so you don't get the parsing error. If you told us the actual error message and gave us the code you're using, perhaps we could help more.

That's a new one. Most people too lazy to do their own work, say their question is urgent.

Read the article I link to in my sig. Then, break down your task into steps and work out how to do them, asking questions here when you get stuck.

OR, contact your rentacoder client and tell them you're not really a programmer at all, and offer to return their money.

Hi,

I had a written a Windows dll in VC++ fours years back. I wasnt to use the dll and call its methods from

How do i call the methods in dll from my C# project. Do I need to write a COM dll to use it in my .Net solution. If yes, how ?

Please suggest me the way to go about it.

Thanks & Regards

Search the hashtable with key is present or not ( C# ASP.NET)

No. You can just use p/invoke to call methods on your object, and you can define structs that mirror any structs used in the C++ code Check out www.pinvoke.net for lots of examples, which are all using Win32 APIs

Member 2503963 wrote:

Use the wizard to create a dll, import your C++ code into it ( so, it's a C++ COM dll ), and then provide a COM interface to yuor methods.

Have you read the documentation? The Hastable class has a ContainsKey[^] method that is used to detect the presence of a particular key.

BTW, unless you are still working with .NET 1.x, you are better off using the generic Dictionary[^] class instead of a Hashtable. The generic Dictionary class allows you to specify exactly what data types the key and value should be, thus enforcing type safety in your data.
