The first thing I tried, is, of course, to follow the advice on the can and remove any tag or text other than “<asp:Content>” tags from the page. But as, you can see, there are no other characters or tags on the page, and I had tried many times to regenerate the page or force VS to “re-parse” the page without success.

After some more debugging for a while, I found this error, which was related to an invalid assembly in the registering custom ASP.NET User Controls section of the web.config document:

Found another error

And the answer? It turns out it was easy enough to fix after all, just fix the offending assembly reference!

The culprit of the error, Only Content controls are allowed directly in a content page that contains Content controls

And voila, fixed:

Fixed!

Download (anylaunch.exe) or compile from source below:

#include <iostream>
#include <windows.h>
#include <cstdlib>
//#define ZeroMemory(p,size) memset((p),0,(size))
using namespace std;

int main(int argc, char* argv[])
{
	if(argc-1 < 1) {
		cout << "No process specified" << endl;
		return 0;
	}

	STARTUPINFO si;
	PROCESS_INFORMATION pi;
	// must blank it
	memset(&si,0,sizeof(si));
	si.cb = sizeof(si);
	si.lpReserved = NULL;
	si.lpTitle = NULL;
	// required for GUI app
	si.dwFlags = STARTF_USESHOWWINDOW;
	si.wShowWindow = SW_MINIMIZE;

	bool res = CreateProcess(NULL,argv[1],NULL,NULL,FALSE,0,NULL,NULL,&si,&pi);
	if(res == false) {
		printf("CreateProcess failed (error code %d)\n", GetLastError());
		return 1;
	}

	CloseHandle(pi.hProcess);
	CloseHandle(pi.hThread);
	return 0;
}

Download or compile the anylaunch executable and put it into the same directory as your script or into the system directory. You can use it in a command line, batch scripting or another program like so:
anylaunch “<process command line here>”

Simple examples (assuming anylaunch is in system path or current folder):

• Launching global executable

  anylaunch explorer

• Launch executable in specific path

  anylaunch "C:\\Tools\\wget.exe http://example.com"

Although the biggest use of this tool is to launch non-exe PE files, like so:

file yes.123

yes.123: PE32 executable for MS Windows (GUI) Intel 80386 32-bit
Then we can use anylaunch to launch this PE file:

anylaunch yes.123

Non-exe process in Task Manager

You may run into some problems while running this. If your command line arguments to your target application are not showing up, you should put your entire command line into one argument and escaping quotes (anylaunch “C:\\Program Files\\Mozilla Firefox\\firefox.exe” not anylaunch C:\Program Files\Mozilla Firefox\firefox.exe). Some other common problems:

Accessing a file that does not exist or is inaccessible (The system cannot find the file specified.):

cat somefile.rnd

cat: somefile.rnd: No such file or directory

anylaunch somefile.rnd

CreateProcess failed (error code 2)

Trying to run an invalid Windows application

file Untitled.png

Untitled.png: PNG image, 800 x 600, 8-bit/color RGB, non-interlaced

anylaunch.exe Untitled.png

CreateProcess failed (error code 11) (An attempt was made to load a program with an incorrect format.)
CreateProcess failed (error code 193) (%1 is not a valid Win32 application.)
etc… (invalid format error, or win32 errors, etc)

Microsoft Word in low colour

To restore the appearance to the full colour style, simply set the colour depth of the operating system to 16-bit or higher by right clicking on the Desktop, selecting Properties and going to the Settings tab, or by selecting Display Resolution, Advanced and going to the Monitor tab. If you want to trigger this look, simply set your colour depth using the same method to 256 colours, and you should be all set.

SSMS Tools Pack generated CRUD

Normally, in SQL Server Management Studio to generate some stored procedures one would have to go through series of dialogs and manual actions using the “Script To” menu. This process is both painful to do by hand and is also very error-prone. Now there is an automated tool that can automate the process of writing stored procedures for us - SSMS Tools Pack.

To automatically generate the select, insert, update and delete procedures all one must do (after installing the free add-on), is right click on a table, go to “SSMS Tools” and “Generate CRUD“, and then Execute the query that it generates. This makes database development much easier compared to doing it by hand.

Prerequisites

A set-up, ready to connect networked virtual PDF converter. This article will only cover connecting, not setting it up.

Procedure

1. Open the “Add Printer” dialogue in Windows. Specify Network printer when asked.
2. Fill out the path to your networked PDF printer as follows: \\<hostname>\<Printer name>
   
3. Click “Yes” and “OK” for the next two warning from Windows.
4. Select the HP LaserJet printer driver as shown as follows:
   
5. After the driver installs, set it as your default printer in Windows or not and print a page to it. You can find the results in your cups-pdf output folder (usually /home/<username>/PDF and /var/spool/cups-pdf/ANONYMOUS for anonymous jobs)

Adding Columns of Data

DataTable dt = new DataTable("Tablename");
dt.Columns.Add("Column1");
dt.Columns.Add("Column2");
dt.Columns.Add("Column3");
// for every row
DataRow dr = dt.NewRow();
dr["Column1"] = "Testing";
dr["Column2"] = "Blah";
dr["Column3"] = "Big Blah";
dt.Rows.Add(dr);

Binding the Data (and storage across sessions)

DataView dv = new DataView(dt);
Session["data"] = dv;
gridviewctrl.DataSource = dv;
gridviewctrl.DataBind();

Paging
Note: This needs AllowPaging to be set to “true”. The following code goes in the “PageIndexChanging” callback.

gridviewctrl.PageIndex = e.NewPageIndex;
gridviewctrl.DataSource = Session["data"];
gridviewctrl.DataBind();

Sorting
Note: This needs AllowSorting to be set to “true” and ensure all columns you want sorted have a “SortExpression” that matches the column name in the DataTable. The following code goes in the “Sorting” callback.

string dir;
if (e.SortDirection == SortDirection.Ascending) {
    dir = "ASC";
} else {
    dir = "DESC";
}
((DataView)Session["Data"]).Sort = e.SortExpression + " " + dir;
gridviewctrl.DataSource = Session["data"];
gridviewctrl.DataBind();

<asp:ButtonField>s
Create a <asp:ButtonField> declaration as follows: <asp:ButtonField ButtonType=”Button” Text=”Button Text Here” CommandName=”DoSomething” />

if (e.CommandName == "DoSomething") {
    // get Index
    int index = Convert.ToInt32(e.CommandArgument);
    string test = ((DataView)Session["Data"]).Table.Rows[index]["Column1"];
    Response.Redirect("http://www.google.com/search?q=" + test.ToString()");
}

1. Try to recreate the Memberships database (ASPNETDB) - it may be corrupt or inaccessible:

   C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regsql -S . -E -A mrpc

2. If that does not resolve the problem for you, the you should check in your web.config file to see if added “Initial Catalog=aspnetdb” somewhere in your web.config file like this:

   Data source=.;Integrated Security=True;Initial Catalog=aspnetdb

3. Restart IIS.

Handler “PageHandlerFactory-Integrated” has a bad module “ManagedPipelineHandler”

It means that you haven not yet run the aspnet_iisreg.exe executable needed to register the ASP.NET 4 framework with the IIS 7 webserver. In order to do so, open a command prompt and type in the following:

C:\windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i

Substitute v4.0.30319 for what other past or future ASP.NET versions. To uninstall the ASP.NET 4 (e.g. for when you are done playing around with it and would like to do some work):

c:\windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -u

To resolve this, make sure there are no copies of the page in the same folder (such as things like backup files, accidental copies, etc) in the same folder. Either move them to a different folder or rename their extensions: .aspx to .aspxold and .cs to .csold.
