RegularExpressionValidator.ValidationExpression="d{10}" means only digits - 10 max.
RegularExpressionValidator.ValidationExpression="d{10,12}" means only digits - 10, 11 or 12.
How to force strictly 10 or 12 symbols?
I am currently working on a web form where you need to make your own account. One of the required fields is where you need to fill in your postal code. I work with an RegularExpressionValidator. This exists out of 4 numbers. The first number may not be a zero. I know that I need the ValidationExpression (propertie of RegularExpressionValidator) but I don't know what to fill in.
View 1 RepliesI found the answer to this, but it's a bit of a gotcha so I wanted to share it here.
I have a regular expression that validates passwords. They should be 7 to 60 characters with at least one numeric and one alpha character. Pretty standard. I used positive lookaheads (the (?= operator) to implement it:
(?=^.{7,60}$)(?=.*[0-9].*)(?=.*[a-zA-Z].*)
I checked this expression in my unit tests using Regex.IsMatch(), and it worked fine. However, when I use it in a RegularExpressionValidator, it always fails.
I'm very new to asp and vb.net, I've just learned about regular expression validation but one thing is bugging me: How can I hide my expression from being viewed on my source code?
The plan is to make a very simple 'login' type of page. I know this goes against all that is holy in this kind of operations, but it's just something I'd like to try out.
Also, after the expression has been validated, I want to load another page, I was thinking of achieving this with:
<asp:TextBox ID="txtcp" runat="server"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ErrorMessage="CP Errada"
Display="Dynamic" ControlToValidate="txtcp" ValidationExpression="admin"></asp:RegularExpressionValidator>
and in vb:
If txtcp is validated then Response.Redirect("mypage.aspx") end if
But the syntax on this IF is obviously not right
i have this ValidationExpression="(d{1,}.{0,2} .{2,})|(.{2,} d{1,}.{0,2})" used in regularexpression validator. I want to use the same one in a customvalidator. But customvalidator does not have option validationexpression. how can i add this in code or in tag.
View 1 RepliesI am using the expression to test for numbers and letters, what do I need to add to also text for "no spaces"?
View 3 RepliesI'm trying to implement a RequiredFieldValidator with a ValidationExpression which is fail validation if the value is -I'm guessing there will probably be a very simple RegEx for it but I am still trying to get my head around it.
View 7 RepliesUsing a RegularExpressionValidator, I want my textbox to accept a max of 20 chars, and only English characters A-Z (upper and lowercase), 0-9, hyphens (-), underscores (_), and spaces. That's it.
Now that I think about it, since this text will be used by a proprietary software to create a file of the same name, and will also be included in the querystring when the page is redirected (so that I can find the file so the user can download it), I'm not sure if I should keep it safe and not accept spaces.
I have a datagrid and I set up the paging based on how many rows there are like this
With dgBookings
.AllowPaging = True
.PagerStyle.Mode = PagerMode.NumericPages
.PagerStyle.PageButtonCount = 5
.PageSize = 5
End With
Is there a way to set the horizontal-align in the code too I tried adding this
.PagerStyle.HorizontalAlign = Right
and I get this errorArgument not specified for parameter 'Length' of 'Public Function Right(str As String, Length As Integer) As String'.
I recently upgraded to Windows 7 64 on my development machine. I am trying to setup my development environment. I have discovered something strange. When trying to set breakpoints in my ASP.Net application the breakpoints will only work if they are in the root folder. My ASP.Net project has various sub folders and any breakpoints in code that is stored in the sub folders turns yellow when debugging starts and states breakpoints will be missed.
I have deleted the temporary folder in c:windowsmicrosoft.netframework .... etc. etc. etc. I have checked the folder permissions in the root and all sub folders (they are the same). I have deleted and rebuilt the subfolders. I have right clicked VS2008 and said to run as administrator. Nothing seems to fix it. I can debug root level code behind pages but anything stored in a subfolder will not debug.
IS it possible to use mathematical symbols in asp.net application.
I am developing a online assessment web application. In that I need to use mathematical sysmbols as question and the user also should be able to use that symbols.
Is it possible? Is any other third party editor is required?
Can I store that symbols into MS SQL database?
Quesion 1:
How to check if a string str1 has at least one of such symbols: ~#$%^&*()[]{}@
Is it possible to solve this quesion using Regex? Any smarter way than this:
If InStr (str1,"~") or InStr (str1,"#") or Then End If
Question 2:
How to check if a string str1 consists of any combination of such symbols without any other symbol: ~#$%^&*()[]{}@
I have created a website in ASP.NET 3.5 that takes some input in text format and saves it in a SQL Server 2005 database.
The database field is varcahar(50).
But I can't do it if data in text box contains special symbols like <,>,#,@,.
It generates a client script error showing security error.
For scripting I am using JavaScript.
Special symbols are a real pain to learn about because you can't Google for them (try doing a Google search for "<%#" and you's get nothing).
I've been a programmer for many years, and I'm trying to get my head around ASP.net, and especially the "special symbols"; what they mean, where to find out more information about them. Because they're impossible to search for, it'd be wonderful if there were special resources in place to help newbies learn about these.
Specifically, I'm looking for detailed instructions on the porpose for, and use, of the following constructs:
<%@ %>
<%$ %>
<%# %>
<%= %>
What is expected in each, what is allowable in each, and what "gotchas" would a newbie have to be careful for when employing each.
For example, I want to do some coding in a <%# %> block, like:
Text="<%# if (Eval("InUse")) {Eval("ProductName")} else {"Not In Use"} %>"
-- would this be allowable, and if not, what are reasonable alternatives?
I get following code (no server error, no html tags nothing... what I am copy pasting is FULL source code).
[Code]....
This goes on in several lines, no eed to repeat it all. There are no html tags, no server error... nothing. It happens on 3 pages, and only common things they have is a texbox TextMode="Multiline"... on first 2 it helped if that text area was empty or without any strange characters.But on 3rd one, I am simply raising postback from a checkbox to display or hide a corresponding textbox... so no data is being sent nothing..... I am totally baffled with this...
Edit: This happens on 2 IIS server (my local machine and other remote IIS that I use) but Cassini actually gives me a message error!
I had an issue when I began working on my project, see this thread where I couldn't debug my DLL's. All I had to do to solve it, though it took me forevever to find this, was to hit F5. This doesn't make much sense since they are DLLs and I get a message that I can't run them directly, but whatever, it works. The output is generated as debuggable and I can copy it to my deployment directory and run and hit BPs (I attach to aspnet_wp).
My VS solution is four projects, all are DLLs, and one is called directly by my web application and it calls the others. There are two I am interested in debugging as I am enhancing them.
Maybe I jinxed myself, but I was actually musing recently that if I never figured out why I couldn't debug I'd never have progressed as much as I had in my task. Yesterday I backed up my project to a zip file - source and DLL's - because I was starting on a new piece. The only thing I did to the solution after that was move a module from App_LocalResources to App_Code, then I moved it back. And I added some code. When I tried to set BP's the next time I ran, I got "symbols not loaded". I haven't been able to debug since. I tried restoring the zip file since yesterday I could debug, but I didn't hit BPs there either. I will be researching this the rest of the day, I am sure, but I thought I would ask for specific since maybe I can tell you something that will you to know what I did wrong or you can throw out a question that will trigger to me what I am doing wrong. This is really not how I wanted to be spending a Friday.
I have to display math symbols in the label text for checkbox. I have created the symbol in MSWord but dont know how is can do that in the website.Is there anyway I can do that.
View 2 RepliesI hate VS and this symbolic gibberish that never seem to have same solution (if it once was logic) twice. The screendump below says what it says.
As soon as I F5/Start the web project, the breakpoint going yellow. This ONLY affect the aspx.cs file that being changed. The other aspx.cs files can have breakpoints.
When I do rebuild/build all DLL and PDB files are created just fine. They have same compile time and are in same directory. Module-Windows i VS says the symbols are loaded perfectly. Well, yeah, try bite me!
I can tell, all symbolic is working just fine, until I was about doing changes inside those aspx.cs files (which was some time ago since last time). If I reset back the file, the breakpoint are working. If I try to make changes in another file, the problem appears there.
It simply appears like that the symbolic file generator don't understand changes maded in aspx.cs files..
I'm writing a banking system and my customer wants support both Russian and American numeric standards in decimal digits delimiter. Respectively . and ,.Now only , works properly. Perhaps because of web server's OS format (Russian is set).String like 2000.00 throws a FormatException: Input string was not in a correct format.How to fix that? I have next two ideas:
protected void FormView1_ItemInserting(object sender, FormViewInsertEventArgs e)

Some days ago all of my projects started working crazily - I'm using VS 2010, .NET 4.0, Silverlight 4 SDK, WP7 SDK. The previously compiled code parts can be debugged as they should be, but as soon as I make any change to the observed .cs file all symbols are ignored.
"The breakpoint will not currently be hit. The source code is different from the original version."
However, the compile is successful, moreover the changes in the code can be seen in the debug mode as well (e.g. if i add messagebox.show(...) it works as expected), but I'm unable to debug the project.
This happens to my Silverlight, WPF, WP7 solutions, Web Applications, so everything important. The most annoying thing is that I even reinstalled Visual Studio, the whole .NET Framework 4 Client Profile, but nothing changed.
I don't want to reinstall the whole OS, but this way i'm unable to work:/
