Hi all,

in my website i need to concatenate some memory streams and export like

response.binarywrite(memorystream.toarray())

in the memory stream i need to concatenate some more memory streams also,
how to do this, is it possible by means of changing by bytes or something like that??

please help me

Do you mean something like this?

MemoryStream MS1 = new MemoryStream(new byte[] { 0x01, 0x02, 0x03 });
MemoryStream MS2 = new MemoryStream(new byte[] { 0x04, 0x05, 0x06 });

MemoryStream MS3 = new MemoryStream();
MS3.SetLength(MS1.Length + MS2.Length);

MS3.Write(MS1.ToArray(), 0, (int)MS1.Length);
MS3.Write(MS2.ToArray(), 0, (int)MS2.Length);

Byte[] Result = MS3.ToArray();
foreach (Byte B in Result)
    Response.Write(B.ToString() + "  ");

thanks for your response,

i tried this code,
but in your code the second line MS3.write will over write(replace) the MS1.

that is my problem here as i am unable to write over, can you tell me more please

Really?

I included test output and it looked like this:

1 2 3 4 5 6

Nothing was overwritten.

here i should get both the report documents result in the pdf,
am i correct..

actually simulatenously i was working and i did some codes though here..

but am getting the last things in the out put..am i not dealing with the streams correctly like closing at appropriate place?

even in the debug mode the Parent1 current postiion is increasing while looping the second one..but am not getting

Concatenating memory streams is available only in .Net version 4. Means there is no option of doing that in previous versions.

you have to implement programming logic to achieve this.

Invalid registration key

Hi, I had set up a pdf maker script using ASPpdf and it had been working fine for several months. Now, when the user trys to create a pdf, they get an Invalid Registration Key error. I looked in regedit for the key as directed in the original instructions and it is there. I don't work with asp.net everyday and haven't done any asp coding in about a year. We had some trouble with the server and our network guys did some work rebuilding. there is a run command showing in the run dropdown that I guess one of the network guys ran. regsvr32 d:\Inetpub\wwwroot\bin\ASPPDFLib.dll
I'm at a loss at what to do.
the line generating the error is below, in C#.

IPdfDocument objDoc = objPdf.CreateDocument( Missing.Value );

Thanks for any help you might provide.

I would like to have an option on the website for people to click and launch a popup. This popup would be like a chat window which always remains on the computer window wherever you drag it. So you can browse the site and still have this popup in the corner. how would we go about doing this?

Have some questions:

Until now edit it so that when you click on the edittemplate appears.

See Picture

Is it possible to change it in such a way that the EditItemTemplate appears when you click on the BoundField ?

Hi! i've seen that you've solved your row sorting problem! nice! Wink | ;)

but now your problem is? you have to read the RowUpdating event and also use the RowCommand event! if you click the 'edit' command, c# runs in RowUpdating event and then fires RowCommand (using e.CommandName as "Edit"). using this you can hide or make visible the columns. ex.

foreach (GridViewRow r in GV_ServiciosDetalles.Rows)
                {
                    ((Panel)r.FindControl("Panel1")).Style.Remove("display");//Make column visible true
                    ((Panel)r.FindControl("Panel2")).Style["display"] = "none";//Make column visible false
                }

So in panel 1 you have a label with Text='<%#Eval("YourBoundField")%>' and in panel 2 you have a textbox with same thing. good luck

Im usin a GridView, Edit, Update, Delete and Cancel are already exist.
Below the Header: SkillGroup is the BoundField and i try to click of the Boundfield.

i aint have no labels. Just boundfield visible ="true"

                    <AlternatingRowStyle BackColor="White" />
                </asp:GridView>

by the way, it is possible to place somewhere a Row in Gridview? Suppose I have a group item and clicking on Add new and under the clicked row
will be added the new row

Using a css class

<style type="text/css" media="screen">
        .hiddencol /*Make invisible the column*/
        {
        	display:none;
        }
        
        .visiblecol /*Make visible the column*/
        {
        	display:block;
        }
    </style>

To hide / show the columns

<Columns>
                        <asp:CommandField HeaderText="Edit-Update" ShowEditButton="True" ItemStyle-CssClass="visiblecol"/>
<asp:ButtonField ButtonType="Link" CommandName="Save" ItemStyle-CssClass="hiddencol" />
                        <asp:BoundField DataField="SkillGroupID" Visible="false" ReadOnly="True" />

<asp:TemplateField>
<ItemTemplate>
<asp:Panel ID="Panel1" runat="server">
<asp:TextBox ID="Txt_Edit" Text='<%#Eval("SkillGroupName") %>' runat="server" Width="60px" ></asp:TextBox>
</asp:Panel>
<ItemStyle CssClass="hiddencol" />
</ItemTemplate>
</asp:TemplateField>

<asp:TemplateField>
<ItemTemplate>
<asp:Panel ID="Panel2" runat="server">
<asp:Label ID="Lbl_Edit" Text='<%#Eval("SkillGroupName") %>' runat="server" Width="60px" ></asp:Label>
</asp:Panel>
<ItemStyle CssClass="visiblecol" /&gt;
</ItemTemplate>
</asp:TemplateField>
                        
<asp:TemplateField>
<ItemTemplate>
<asp:ImageButton ID="ImageButton1" runat="Server" ImageUrl="~/Image/Hoch.JPG" CausesValidation="false" CommandName="Up" CommandArgument='<%# Container.DataItemIndex %>' Visible="True" />
<asp:ImageButton ID="ImageButton2" runat="Server" ImageUrl="~/Image/Runter.JPG" CausesValidation="false" CommandName="Down" CommandArgument='<%# Container.DataItemIndex %>' Visible="True" />;
</ItemTemplate>
</asp:TemplateField>
<asp:CommandField HeaderText="Delete" ShowDeleteButton="True" />
</Columns>

then in your RowCommand you can change the 'visiblecol' style by 'hiddencol' and 'hiddencol' by 'visiblecol' like I've posted before
