Mysterious gray line when two rectangles are side by side

Posted By:      Posted Date: October 22, 2010    Points: 0   Category :WPF
 

Hello, I am new to the WPF and have a small, but extremely annoying problem.   There appears to be some sort of gray line that appears when I put two rectangles side by side.  Only during certain window sizes does this line appear, I assume this has something to do with the rendering and having an odd # of pixels or something, not really sure.   But this is unacceptable for what I am trying to accomplish, so, I am hoping to get some assistance here please, please review this XAML and when you run it .. you will see that as you change the window to various sizes between my two black rectangles you will notice a gray line that appears and disappears depending on what size the window is.

Thank you,

Mike

 

PS. I am using MS VS 2008 and have tested this on XP and windows 7, and found the same problem in both platforms.

 

Code:

<Window x:Class="Window1"
  xmlns="http://schemas

side by side DIVs don't line up on same horizontal line.

  
the following html is intended to render 2 fixed height DIVs side by side, on the same line. Odd thing is, when I add some text content such as <span>, <p> or <h1>, to one of the divs, that div is drawn down by a varying number of lines. ( depending on the number of lines of block level content. ).  When I duplicate the content in both divs, they snap back up and line up on the same horizontal line. I am getting this behavior in both chrome and IE8.  Is there an explanation? <div style="height:160px; width:200px; display:inline-block;            border:1px solid black;margin:0;padding:0;"><p>line 1</p><p>line 2</p></div> <div style="height:160px; width:200px; display:inline-block;            border:1px solid black;margin:0;padding:0;"></div> thanks,  

call JavaScript - jQuery code from ASP.NET Server-Side

  
jQuery got so close to me lately that I can see myself adding the scripts to my project almost unconsciously. The thing is, jQuery is very useful for me, in almost all situations and it has been a do or die enhancement for all my project since I first put my hands on it.

Of course while using it, you encounter few situations which need a bit of research to solve, mostly when you are trying to combine it with some other technologies like: UpdatePanels and ASP.NET Ajax. For instance there are many situations when I would like to run some jQuery magic based on some decision that I make on the server side.

Use jQuery and ASP.NET AJAX to build a client side Repeater

  
By sending only data to the client, you can profoundly reduce the size of what you send and see a substantial increase in performance. You also allow yourself the ability to easily add features like light-weight sorting and paging on the client. This can not only improve your users' experience, but reduce server load and bandwidth requirements.

Accessing SharePoint 2010 Data with Server-Side APIs

  
Accessing SharePoint data in server-side solutions is one of the most common tasks that you will perform as a SharePoint developer. SharePoint 2010 provides powerful server-side APIs that enable you to retrieve, add, edit, and delete SharePoint data programmatically. SharePoint 2010 also includes the new LINQ to SharePoint technology that enables you to work with SharePoint data efficiently and easily.

Adding Client-Side Confirmation When Deleting

  
The JavaScript confirm(string) function displays its string input parameter as the text inside a modal dialog box that comes equipped with two buttons - OK and Cancel (see Figure 1). The confirm(string) function returns a Boolean value depending on what button is clicked (true, if the user clicks OK, and false if they click Cancel).

Server side validation of Fileupload control not working

  
 

 


I've tried this method in my code behind to try and validate that the Fileupload control has a file or not. I get the error message the the event "Server Validate" cannot be found. Can anyone tell why? Thanks.


Public Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate
       

' Get file name

        Dim uploadAvatar As FileUpload = DirectCast(AdvertisementForm.FindControl("uploadAvatar"), FileUpload)

        Dim UploadFileName As String = uploadAvatar.PostedFile.FileName

        If UploadFileName = "" Then
            ' There is no file selected
            args.IsValid = False
        Else
            Dim Extension As String = UploadFileName.Substring(UploadFileName.L

divs do not display side by side

  

I have two divs. I want them to display side by side, on the same row. Using display:inline-block I can do that. But as soon as I position some text in the bottom right corner of div1, the two divs do not have the same vertical position. They are side by side, but the 2nd div starts at the vertical position of the positioned text in the 1st div.   Why would it do that?  Both Chrome and IE8 render it the same way.

( I am doing the nesting of the divs on the left side so that I can position absolutely within a div and not the page. I can't get text to position in the lower right corner of a div any other way. )


thanks,

  <div style="border:2px solid black;">
    <div style="display:inline-block;">
      <div style="width:10em; height:4em; background:orange;color:White;
           position:relative;">
        <span style="position:absolute;bottom:0px;right:0px;">

        </span>

server side does not save data when using POST data to another URL using WebRequest

  

Hi,
 I am using a IIS 7.5 on Windows 7. I have a simple application that uses System.Net.WebRequest to POST data to another URL (in fact, the server side URL is on my local computer and it is hosted in IIS 7.5).

  1.  The problem is the server does not save data from client although on the client side codes when I debug and I see the OK message return from the code line

   response.StatusDescription; // this has value of "OK"
 
 
2. How can I debug the server code side where to receive the request from client side who posts the data ?
 


The following is the codes for client who posts data using System.Net.WebRequest, and codes for server side who received posted data to save to database.


Client side codes: // also run on my local computer

public string PostIntegrationXml(XmlDocument xmlSubmitDoc)

        {
