			<content:encoded><![CDATA[<p>Yaklaşık bir seneden beri merakla beklediğim Crystal Reports&#8217;un Visual Studio 2010 için olan sürümü sonunda dağıtım sürümüne ulaştı. Yeniliklerden bazıları şöyle:</p>
<ul>
<li>WPF için görüntüleyici desteği (WPF based Crystal Reports Viewer control)</li>
<li>Basitleştirilmiş paket</li>
<li>Adobe Flash desteği</li>
</ul>
<p><a href="http://xspgroup.files.wordpress.com/2010/12/cr-v13.png"><img class="aligncenter size-full wp-image-1754" title="Crystal Reports v13 Visual Studio 2010" src="http://xspgroup.files.wordpress.com/2010/12/cr-v13.png?w=640" alt="Crystal Reports v13 Visual Studio 2010"   /></a></p>
<p>Benim testlerime göre:</p>
<ul>
<li>Raporlar daha hızlı yüklenmekte ve beklemeyi minimuma indirmekte.</li>
<li>Görüntüleme dili olarak Türkçe desteği eklenmiş.</li>
<li>Rapor boyutu olarak kullanıcı tanımlı boyut eklenmiş (tam test edemedim)</li>
</ul>
<p>Crystal Reports&#8217;un yeni versiyonunu <a href="http://www.businessobjects.com/jump/xi/crvs2010/default.asp" target="_blank">şuradan</a> indirebilirsiniz.</p>

<p style="padding-left:30px;"><em>Checks whether SQL Server 2005 Express Tools are installed.</em></p>
<p style="padding-left:30px;"><em>The SQL Server 2005 Express Tools are installed. To continue, <strong>remove the SQL Server 2005 Express Tools.</strong></em></p>
<p>Daha önde SQL 2005 kurulu idi fakat bunu kaldırmak istemediğimden ve kaldıracak böyle bir kurulum olmadığından birazcık araştırma yaptım ve sorunun kısa yoldan çözümünü buldum.</p>
<p>x64 sistemler için:<br />
Registry&#8217;den <strong>HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SQL Server\90</strong> ve <strong>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\90</strong> adlı kaydın adını değiştirin. (90old gibi)</p>
<p>x86 sistemler için de <strong>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\90</strong> adlı kaydın adını değiştirin.</p>

			<content:encoded><![CDATA[<p>Veritabanından çektiğim kategori navigasyonu için tekrardan veritabanı işlemleri yapmamak adına pratik bir fonksiyon yazayım dedim. Fonksiyon <strong>Ürünler » Çikolatalar » Alpella</strong> gibi bir metinsel ifadeyi <strong>Alpella « Çikolatalar « Ürünler</strong> şekline çevirmekte kullanılabilir. Stackoverflow&#8217;da sorduğum <a href="http://stackoverflow.com/questions/2934936/suggestion-to-reverse-string-in-c" target="_blank">soruya</a> daha kısa alternatif ise Linq sınıfını kullanan bir kod tavsiye edildi. Onu da altta veriyorum.</p>
<p><code><br />
public static string ReverseString(string input, string separator, string outSeparator)<br />
{<br />
string result = String.Empty;<br />
string[] temp = Regex.Split(input, separator, RegexOptions.IgnoreCase);<br />
Array.Reverse(temp);<br />
for (int i = 0; i &lt; temp.Length; i++)<br />
{<br />
result += temp[i] + " " + outSeparator + " ";<br />
}<br />
return result;<br />
}<br />
</code><br />
Not: System.Text.RegularExpressions sınıfını kullanır.</p>
<p>Stackoverflow alternatifi:</p>
<p><code><br />
public static string ReverseString(string input, string separator, string outSeparator)<br />
{<br />
return String.Join(" " + outSeparator + " ", input.Split(new[] { " " + separator + " " }, StringSplitOptions.RemoveEmptyEntries).Reverse().ToArray());<br />
}<br />
</code><br />
Not: System.Linq sınıfını kullanır.</p>
<p>Ayrıca stackoverflow tavsiyelerine göre fonksiyonu StringBuilder ile kullanmak uzun metinsel ifadelerde performans sağlayacaktır:</p>
<p><code><br />
public static string ReverseString(string input, string separator, string outSeparator)<br />
{<br />
StringBuilder result = new StringBuilder();<br />
string[] temp = Regex.Split(input, separator, RegexOptions.IgnoreCase);<br />
Array.Reverse(temp);<br />
for (int i = 0; i &lt; temp.Length; i++)<br />
{<br />
result.Append(temp[i] + " " + outSeparator + " ");<br />
}<br />
return result.ToString();<br />
}<br />
</code></p>

Bu da tasarladığımız web sitesindeki iletişim formuna Türkçe domain sahiplerinin e-postalarını girmemesine neden olacaktır.</p>
<p><img class="aligncenter size-full wp-image-1332" title="İletişim formu" src="http://xspgroup.files.wordpress.com/2010/03/form.jpg?w=640" alt="İletişim formu"   /></p>
<p>Son tasarladığım bir web projesinde bu nokta sonunda beni araştırmaya sevk etti. Fakat pek de istediğim gibi birşey bulamadığımdan ifadeyi (expression) kendim yazdım. İfade şu şekilde:</p>
<p><code>\w*[\wçığöşü]+([-+.']\w+)*@\w*[\wçığöşü]+([-.]\w+)*\.\w+([-.]\w+)*</code></p>
<p>Bunu bir örnekte açıklayacak olursak formumuzda aşağıdaki kod yer almalı. Ayrıca bir de requiredFieldValidator koyuyorum ki e-posta kutucuğu boş da bırakılamasın.</p>
<p><code><br />
&lt;asp:TextBox ID="tEPosta" runat="server" CssClass="input" /&gt;<br />
&lt;asp:RequiredFieldValidator ID="rfvEPosta" runat="server" ControlToValidate="tEPosta" ErrorMessage="* zorunlu" Display="Dynamic" /&gt;<br />

			<content:encoded><![CDATA[<p>Today I got this error while I was coding a cms panel. I&#8217;ve researched for solution but there was nothing to do with most of them. Then I&#8217;ve looked up my code and I&#8217;ve realized that I haven&#8217;t closed my reader. After I added rdr.Close(); to my code block before closing <span style="text-decoration:underline;">using</span> statement, problem was solved.</p>
<p>Also you can add rdr.Dispose(); In my code I delete previous uploaded files and sometimes it gives error when the file that needs to be deleted is already deleted. And this is the reason why command cannot be closed. So close and dispose the reader. Problemo solved <img src='http://s0.wp.com/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>

<ul>
<li>SqlConnection.ClearPool( SqlConnectionObject );</li>
<li>SqlConnection.ClearAllPools();</li>
</ul>
<p>Dikkat etmeniz gereken şey bu satırı kullanmanız halinde nerede kullandığınıza bağlı olarak geçerli bağlantıların da sonlandırılabilme tehlikesidir. En zararsız kullanım için bağlantıyı açarken ilk önce normal olarak açmaya denemeli ve hata oluşması halinde havuzları temizlemelisiniz.</p>
<p>Tam hata:</p>
<p><code>Zaman aşımı süresi doldu. Havuza bağlantı elde edilemeden zaman aşımı süresi doldu. Bu, tüm havuz bağlantıları kullanıldığı ve en büyük havuz boyutuna erişildiği için oluşmuş olabilir.</code></p>
<p>İlgili bağlantılar:</p>

<p>If your aspx page has AutoEventWireup = &#8220;true&#8221; property and the button has onclick = &#8220;Upload_Click&#8221; property and at the same time the procedure has Handles Upload.Click that will cause code run twice when the button is clicked.</p>
<p>Solution: Set AutoEventWireup = &#8220;false&#8221; and remove onclick property from the button or leave AutoEventWireup = &#8220;true&#8221; and remove Handles Upload.Click from the related event&#8217;s procedure.</p>

			<content:encoded><![CDATA[<p>ReklamIC projesi üzerinde uğraşırken birkaç sayfada bu hatayla karşılaştım. Hata genellikle bir sayfadaki url&#8217;den yine aynı sayfadaki bir bağlantıdan aynı sayfaya veri gönderince gerçekleşmekte. Mesela ReklamGoruntule.aspx&#8217;te ReklamGoruntule.aspx?deger=1 şeklinde bir bağlantıya tıklarsanız böyle bir hata meydana gelir.</p>
<p>Hatayı meydana getiren kısım ViewZones.aspx sayfasındaki nesne idi:</p>
<p><code>&lt;asp:ImageButton AlternateText="Yayın Kodunu Al" ToolTip="Yayın Kodunu Al" ID="ImageButton3" runat="server" ImageUrl="~/images/code.png" Width="32" Height="32" PostBackUrl='&lt;%# Eval("ZoneID","ViewZones.aspx?zid={0}") %&gt;' /&gt;<br />
</code></p>
<p>Ben sorunu page_load&#8217;daki veri yükleme kodlarını If Not Page.IsPostBack Then &#8230;veri yüklemeleri&#8230; End If şeklie getirerek çözdüm. Çeşitli kaynaklarda söylenen pages validateRequest=&#8221;false&#8221; veya enableEventValidation=&#8221;false&#8221; şeklindeki düzenlemeler sorununuzu çözer belki ama benim tavsiyem bunu kullanmamanız. Çünkü saldırılara bir kapı açmış olursunuz.</p>
<p>Tam Hata :<br />
<code>Invalid postback or callback argument.  Event validation is enabled using<br />
in configuration or &lt;%@ Page EnableEventValidation="true" %&gt; in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.</code></p>
